To avoid an EGL stream in the wrong state, if the window pixmap changed
before the stream was connected, we would still keep the pending stream
but mark it as invalid. Once the callback is received, the pending would
be simply discarded.
But all of this is actually to avoid a bug in egl-wayland, there should
not be any problem with Xwayland destroying an EGL stream while the
compositor is still using it.
With that bug now fixed in egl-wayland 1.1.7, we can safely drop all
that logic from Xwayland EGLstream backend.

When building xserver with slibtool (https://dev.midipix.org/cross/slibtool)

/usr/bin/ld: cannot find -ldmxconfig
This is because xserver creates libdmxconfig.a internally and then links with
the linker flag -ldmxconfig. However according to automake documentation the
-lfoo linker flags should only be used for external dependencies and all
internal libraries should be linked with the libtool archive file (.la) or

GNU libtool is far more permissive and happens to silently obscure this issue
while slibtool fails because it instead sees '-L./.libs -ldmxconfig'.

In certain circumstances we will have a lot of flip errors without a
reasonable way to prevent them. In such case we reduce the number of
logged messages to at least not fill the error logs.
The details are as follows:
At least on i915 hardware support for async page flip support depends on
the used modifiers which themselves can change dynamically for a screen.
This results in the following problems:
- We can't know about whether a particular CRTC will be able to do an
async flip without hardcoding the same logic as the kernel as there's no
interface to query this information.
- There is no way to give this information to an application, because
the protocol of the present extension does not specify anything about
changing of the capabilities on runtime or the need to re-query them.
Even if the above was solved, the only benefit would be avoiding a
roundtrip to the kernel and reduced amount of error logs. The former
does not seem to be a good enough benefit compared to the amount of work
that would need to be done. The latter is solved in this commit.

Currently, the EGLstream backend would increment the pixmap refcount for

But that's relying on the compositor sending us a release callback for
each commit, otherwise the pixmap refcount will keep increasing and the
pixmap will be leaked.
So instead, increment the refcount on the pixmap only when we have not
received a release notification for the wl_buffer, to avoid increasing
the pixmap refcount more than once without a corresponding release
event.
This way, if the pixmap is still in use when released on the X11 side,

As a result, we may end up with the EGL stream in the wrong state when

To avoid the problem, increase the reference count on the pixmap when it

Previously, we would have pending streams associated with top level X11
windows, keeping temporary accounting for the pending streams before
they get fully initialized for the xwl_pixmap which would be associated
with X11 pixmaps.
If the window content changes before the stream is ready, the
corresponding pending stream would be marked as invalid and the pending
stream would be eventually removed once the stream becomes ready.
Since commit affc47452 - "xwayland: Drop the separate refcount for the
xwl_pixmap", we no longer keep a separate reference counter for the
xwl_pixmap, but rather tie it to the X11 pixmap lifespan. Yet, the
pending stream would still be associated with the X11 toplevel window.
Dissociate the pending streams from the X11 toplevel window, to keep it
tied only to the xwl_pixmap so that we can have:
- pixmap <-> xwl_pixmap
- xwl_pixmap <-> pending stream
Of course, the pending streams remain temporary and get removed as soon
as the ready callback is triggered, but the pending streams are not
linked to the X11 window anymore which can change their content, and
therefore their X11 pixmap at any time.

To hopefully make this less error-prone, we also introduce a "type"

Additionally, the patch enables wnmd present mode with the eglstream backend.
This involves creating a wl_buffer for the provided dma-buf before importing it
into EGL and passing this to the compositor so it can be scanned out directly

Fixes: 20c78f38 - xwayland: use get_pointer_device() for enter/leave
handling too
The code path added by commit 69e4b8e6 (xfree86: attempt to autoconfig
gpu slave devices (v3)) assumes that it will only be run if the primary
device on the screen is the first device in xf86configptr->conf_device_lst.
While this is true most of the time, there are two specific cases where
this assumption fails.
First, if the first device in conf_device_lst is assigned to a different
seat than the running X server, it will be skipped by the previous
FIND_SUITABLE macro usage. Second, if the primary device was explicitly
assigned to the screen but auto_gpu_device is still set and no secondary
devices were explicitly listed, that device may not be the first device
in conf_device_lst.
When the first device in conf_device_lst is not the primary device
assigned to the screen, two problems emerge. First, the first device in
conf_device_lst will never be assigned to the screen as a secondary
device. Second, the primary device is additionally assigned to the
screen as a secondary device. The combination of these problems causes
certain otherwise valid configurations to be invalid. For example, if a
primary device is assigned to a screen and a secondary device is listed
in the config but not explicitly assigned to the screen, then one order
of the device sections results in a usable PRIME or Reverse PRIME setup
and the other order does not.
This commit removes the assumption that the primary device is the first
device in conf_device_lst by starting the loop from the start of
conf_device_lst and skipping the primary device when it is encountered.

Xwayland won't emulate XWarpPointer requests if the cursor is visible,
this is to avoid having the cursor jumping on screen and preventing
random X11 clients from controlling the pointer in Wayland, while
allowing games which use that mechanism with a hidden cursor to work in
Xwayland.
There are, however, games which tend to do it in the wrong order, i.e.
show the cursor before moving the pointer, and because Xwayland will not
allow an X11 client to move the pointer while the cursor is visible, the
requests will fail.
Add a workaround for such X11 clients, when the cursor is being shown,
keep it invisible until the cursor is actually moved. This way, X11
clients which show their cursor just before moving it would still have a
chance to succeed.
v2: Add a timeout to show the cursor for well behaved clients.
v3: Some cleanup (Michel)
v4: Do not cancel cursor delay when updating the cursor to avoid
delaying cursor visibility indefinitely if the client keeps
settings different cursors (Michel)

In Weston, clicking the window decoration of an Xwayland client gives us a
wl_pointer.button event immediately followed by a wl_pointer.leave event.
The leave event does not contain any button state information, so the button
remains logically down in the DIX.
Once the pointer button is released, a wl_pointer.enter event is sent with
the current button state (zero). This needs to trigger a ButtonRelease event
but for that we need to ensure that the device is the same as the one we send
ButtonPress events through.

Xwayland supports relative motion events from the Wayland compositor via

in device units for raw events.
Some X11 clients however wrongly assume relative values in the axis
values even for devices explicitly labeled as absolute. While this is a
bug in the client, such applications would work fine in plain Xorg but
not with Xwayland.
To avoid that issue, use the relative values for raw events without
conversion, so that such application continue to work in Xwayland.

This add a new flag POINTER_RAWONLY for GetPointerEvents() which does
pretty much the opposite of POINTER_NORAW.
Basically, this tells GetPointerEvents() that we only want the
DeviceChanged events and any raw events for this motion but no actual
motion events.
This is preliminary work for Xwayland to be able to use relative motion
events for raw events. Xwayland would use absolute events for raw
events, but some X11 clients (wrongly) assume raw events to be always
relative.
To allow such clients to work with Xwayland, it needs to switch to
relative raw events (if those are available from the Wayland
compositor).
However, Xwayland cannot use relative motion events for actual pointer
location because that would cause a drift over time, the pointer being
actually controlled by the Wayland compositor.
So Xwayland needs to be able to send only relative raw events, hence
this API.
Bump the ABI_XINPUT_VERSION minor version to reflect that API addition.

When an X11 client issues an active grab on the keyboard, Xwayland
forward this to the Wayland compositor using the Xwayland specific
protocol "xwayland-keyboard-grab" if it can find the corresponding
Xwayland window.
Some X11 clients (typically older games) however try to issue the
keyboard grab on the X11 root window, which has obviously no matching
Xwayland window. In such a case, the grab is simply ignored and the game
will not work as expected.
To workaround that issue, if an X11 client issues a keyboard grab on the
root window, Xwayland will search for a toplevel window belonging to the
same X11 client that it can use as the grab window instead.
This way, the grab can be forwarded to the Wayland compositor that can
either grant or deny the request based on the window and its internal
policies.
The heuristic picks the first realized toplevel window belonging to the
client so that the Wayland compositor will send it the keyboard events,
and the Xserver grab mechanism will then take care of routing the events
to the expected X11 window by itself.

One general assumption in Xwayland is that the xwl_window remains the
same for all the child windows of the toplevel window.
When mapping a new X11 window, ensure_surface_for_window() checks for an
existing xwl_window by using xwl_window_get() which will just check for
the registered xwl_window for the window.
That means that a client mapping a child window of an existing window
with a xwl_window will get another different xwl_window.
If an X11 client issues a Present request on the parent window, hence
placed underneath its child window of the same size, the Wayland
compositor may not send the frame callback event for the parent's
Wayland surface which is reckoned to be not visible, obscured behind
the other Wayland surface for the child X11 window.
That bug affects some games running in wine which may get 1 fps because
the repaint occurs only on timeout with a long interval (as with, e.g.

There was a time when setting a mode on a CRTC would not depend on the
associated connector's state. If a mode had been set successfully once,
it would mean it would work later on.
This changed with the introduction of new connectors type that now
require a link training sequence (DP, HDMI 2.0), and that means that
some events may have happened while the X server was not master that
would then prevent the mode from successfully be restored to its
previous state.
This patch relaxes the requirement that all modes should be restored on
EnterVT, or the entire X-Server would go down by allowing modesets to
fail (with some warnings). If a modeset fails, the CRTC will be
disabled, and a RandR event will be sent for the desktop environment to
fix the situation as well as possible.
Additional patches might be needed to make sure that the user would
never be left with all screens black in some scenarios.

Normally, we would receive a uevent coming from Linux's DRM subsystem,
which would trigger the check for disappearing/appearing resources.
However, this event is not received when X is not master (another VT
is selected), and so the userspace / desktop environment would not be
notified about the changes that happened while X wasn't master.
To fix the issue, this patch forces a refresh on EnterVT by splitting
the kms-checking code from the uevent handling into its own (exported)
function called drmmode_update_kms_state. This function is then called
from both the uevent-handling function, and on EnterVT right before
restoring the modes.

However, when this pending queue is freed, the corresponding private

These changes have been ported from AMD GPU DDX driver.
This patch adds support for setting the CRTC variable refresh property
for suitable windows flipping via the Present extension.
In order for a window to be suitable for variable refresh it must have
the _VARIABLE_REFRESH property set by the MESA and inform Modesetting
DDX driver with window property updates.
Then the window must pass the checks required to be suitable for
Present extension flips - it must cover the entire X screen and no
other window may already be flipping. And also DRM connector should
be VRR capable.
With these conditions met every CRTC for the X screen will have their
variable refresh property set to true.

This reverts commit 427f8bc009.
When receiving an output update for the mode size we need to rotate the stored

since in this case the stored values describe the output's size in logical
space, i.e. rotated.
The here reverted commit made a code change with which we would not rotate though
when an xdg-output was available since in this case the need_rotate variable was
set to False what caused in the check afterwards the first branch to execute.
That is just a small style-change to the output_get_new_size function. The
function before did take first the height and then the width argument, what

Xwayland is usually spawned by the Wayland compositor which sets the
command line options.
If a command line option is not supported, Xwayland will fail to start.
That somehow makes the Xwayland command line option sort of ABI, the
Wayland compositor need to know if a particular option is supported by
Xwayland at build time.
Also, currently, Xwayland is being installed along with the rest of the
common executable programs that users may run, which is sub-optimal
because, well, Xwayland is not a common executable program, it's meant
to be a proxy between the Wayland compositor and the legacy X11 clients
which wouldn't be able to run on Wayland otherwise.
Xwayland would be better installed in `libexec` but that directory is
(purposedly) not in the user `PATH` and therefore the Wayland compositor
may not be able to find Xwayland in that case.
To solve both problems (which options are supported by Xwayland and
where to look for it), add a `pkg-config` file specifically for Xwayland
which gives the full path to Xwayland (`xwayland`) and which options it
supports (using `pkg-config` variables).
The `pkg-config` file also provides the `Version` so the build scripts
can check for a particular version if necessary.
Obviously, Wayland compositors are not required to use the `pkg-config`
file and can continue to use whatever mechanism they deem preferable.

The way Xwayland works (like all Wayland clients), it first queries the
Wayland registry, set up all relevant protocols and then initializes its
own structures.
That means Xwayland will get the Wayland outputs from the Wayland
compositor, compute the physical size of the combined outputs and set
the corresponding Xwayland screen properties accordingly.
Then it creates the X11 screen using fbScreenInit() but does so by using
a default DPI value of 96. That value is used to set the physical size
of the X11 screen, hence overriding the value computed from the actual
physical size provided by the Wayland compositor.
As a result, the DPI computed by tools such as xdpyinfo will always be
96 regardless of the actual screen size and resolution.
However, if the Wayland outputs get reconfigured, or new outputs added,
or existing outputs removed, Xwayland will recompute and update the
physical size of the screen, leading to an unexpected change of DPI.
To avoid that discrepancy, use a fixed size DPI (defaults to 96, and can
be set using the standard command lime option "-dpi") and compute a
physical screen size to match that DPI setting.
Note that only affects legacy core protocols, X11 clients can still get
the actual physical output size as reported by the Wayland compositor
using the RandR protocol, which also allows for the size to be 0 if the
size is unknown or meaningless.

Xwayland uses the device private to point to the `xwl_seat`.
Device may be removed at any time, including on suspend.
On resume, if the DIX code ends up calling a function that requires the
`xwl_seat` such as `xwl_set_cursor()` we may end up pointing at random
data.
Make sure the clear the device private data on removal so that we don't
try to use it and crash later.

In this pretty Wine/Proton specific kludge, we try to handle confining grabs
on InputOnly windows by trying to find the InputOutput window that the pointer
would get visually confined to.
The grabbing window and the visible window come from different clients, so
we used to simply resort to the pointer focus. This is troublesome though, as
the call may happen very soon at a time that the toplevel wasn't yet mapped by
the Wayland compositor, so the pointer focus may well be out of date soon.
In these situations, it does seem that even though the confining grab happens
too early to have the wayland surface mapped, the xserver view of the WindowPtr
does already reflect the size. Use this to find out the better window to
assign the confining grab to, one whose geometry fully contains the InputOnly
window's.

When an X11 client issues a ConfinePointer wit ha hidden cursor,
Xwayland may translate that as a pointer lock.
However, if the pointer is located on another window at the time,

To avoid that issue, check again if locking the pointer with a hidden

When an X11 client has an active grab on the pointer, all events are
reported relative to the window with the grab.
For Xwayland, if an X11 client has a grab with a pointer confinement
active, while pointer focus is on another window, motion events should
not be reported to the client with the grab, because that sets the X11
client appart, the events would be reported when the pointer is on any
X11 window but not on Wayland native surfaces.
Therefore, if the pointer is confined on a window and that window
differs from the actual pointer focus window, just pretend we lost
pointer focus to another window.

If a client issues a grab on the pointer while the cursor is on another
X11 window, and then hides the cursor, we may end up locking the pointer
onto that other window.
Then a button click might end up moving the focus away from the window
which issued the grab, leaving the whole setup in a mixed up state.
Typically, if the pointer is on another X11 window, we should not try to
lock the pointer, so that it can be moved back to the window which
actually issues the grab (and hence the pointer confinement). Typically,
this is the same as an X11 client issuing a pointer grab while the
cursor is on another Wayland native window.

Mutter recently added headless tests, and when running those tests the
Wayland compositor runs for a very short time.
Xwayland is spawned by the Wayland compositor and upon startup will
query the various Wayland protocol supported by the compositor.
To do so, it will do a roundtrip to the Wayland server waiting for
events it expects.
If the Wayland compositor terminates before Xwayland has got the replies
it expects, it will loop indefinitely calling `wl_display_roundtrip()`
continuously.
To avoid that issue, add a new `xwl_screen_roundtrip()` that checks for
the returned value from `wl_display_roundtrip()` and fails if it is
negative.

All helper client code now uses xcb, so calling XSetAuthorization() is
no longer needed.
This is the last reference to libX11 from helper clients, so linking
with x11-xcb and libX11 is no longer required.
Also drop (unneeded?) linking with libXau.
Also drop installing these prerequistes on AppvVeyor.
Also move prototypes for functions in winauth.c from win.h into a new
header, winauth.h, and include that where needed.
Convert clipboard integration code from libX11 to xcb
This drops support for COMPOUND_TEXT. Presumably some ancient
(pre-2000) clients exist which support that, but not UTF8_STRING, but we
don't have an example to test with. (Given the nature of the thing, the
users of those clients probably work in CJK languages)
Supporting COMPOUND_TEXT would also involve writing (or extracting from
Xlib) support for the ISO 2022 encoding.
v2:
Fix the length of text property set by a SelectionRequest
The length of the text property is not neccessarily the same as the
length of the clipboard text before it is d2u converted (specifically,
if that contains any '\r\n' sequences, it will be shorter as they are
now just '\n')
Always use CF_UNICODETEXT clipboard format. Windows will automatically
down-convert to CF_TEXT for clients which request that.
This is subtly different in one way: if CF_TEXT is requested, we now
post CF_UNICODETEXT and it is converted to CF_TEXT *in the locale of the
requesting process*. Previously, we would convert to CF_TEXT *in our
locale* and post that.
It looks like the code in the !X_HAVE_UTF8_STRING case didn't actually
work correctly, but fortunately that has never been true...
The original Win32 clipboard API is widely regarded as terrible, since
it relies on clients co-operatively managing the clipboard viewer chain,
and a single buggy client can break it for all other clients.
The last Windows version only supporting that API was Windows XP (5.1),
EOLed in 2014.
(This requires MinGW-w64 w32api 6.0.0 or later for
Add/RemoveClipboardListener correctly exported by the x86_64 user32
implib)
Also, relax the timeout mechanism so it allows 1 second between events,
rather than 1 second for the entire transfer, as transfers of large
pastes can take more than 1 second.
Also, prefer UTF8_STRING encoding to COMPOUND_TEXT encoding
This option was implemented before the drivers were split in ≈2006,
and e.g. XWin still supports it.

xwl_output_set_window_randr_emu_props() case.

For window-manager managed windows, xwl_realize_window is only called for
the window-manager's decoration window and not for the actual client window
on which we should set the _XWAYLAND_RANDR_EMU_MONITOR_RECTS prop.
Usualy this is not a problem since we walk all client windows to update
the property when the resolution is changed through a randr call.
But for apps which first do the randr change and only then create their
window this does not work, and our xwl_output_set_window_randr_emu_props
call in xwl_realize_window is a no-op as that is only called for the wm
decoration window and not for the actual client's window.
This commit fixes this by making ensure_surface_for_window() call
xwl_output_set_window_randr_emu_props on the first and only child of
window-manager managed windows.
Note this also removes the non-functional xwl_output_set_window_randr_emu_props
call from xwl_realize_window, which was intended to do this, but does not
work.
This fixes apps using the ogre3d library always running at the

Some clients, which use vidmode to change the resolution when going fullscreen,
create an override-redirect window and never trigger the screen->ResizeWindow
callback we rely on to do the xwl_window_check_resolution_change_emulation().
This causes us to not apply a viewport to them, causing the fullscreen window
to not fill the entire monitor.
This commit adds a call to xwl_window_check_resolution_change_emulation()
at the end of ensure_surface_for_window() to fix this. Note that
ensure_surface_for_window() exits early without creating an xwl_window
for new windows which will not be backed by a wayland surface and which
thus will not have an xwl_window.

mode_width = xwl_output->width;
mode_height = xwl_output->height;
} else {

}
This means we need to do something similar in xwl_output_set_emulated_mode()
to determine if the mode being set is the actual (not-emulated) output mode
and we this should remove any emulated modes set by the client.
All callers of xwl_output_set_emulated_mode always pass a mode pointer
to a member of xwl_output->randr_output->modes, so we do not need to
duplicate this code, instead we can simply check that the passed in mode
is modes[0] which always is the actual output mode.

When fullscreening a X11 window, mutter moves its window-decoration Window
wrapping the top-level Window to the monitor's origin coordinates (e.g. 0x0)
last. This updates the top-level's drawable coordinates, but as the
actual MoveWindow is called on the wrapper Window and not on the toplevel

On the particular machine I was trying to set up an UDL device,
I found the following structure was being used to match
the device to a platform device while I was debugging the issue:
xf86_platform_devices[0] == Intel, /dev/dri/card1, primary platform device
xf86_platform_devices[1] == UDL, /dev/dri/card0
devList[0] == "Intel0", ZaphodHeads: DP1
devList[1] == "Intel1", ZaphodHeads: VGA1
devList[2] == "UDL"
devList[3] == "Intel2", ZaphodHeads: HDMI1 (intended GPU device to UDL)
When xf86platformProbeDev() matched the UDL device, the BusID
check failed in both cases of:
* BusID "usb:0:1.2:1.0" was specified
* Option "kmsdev" "/dev/dri/card0" was specified
As a result, xf86platformProbeDev() went on to call probeSingleDevice()
with xf86_platform_devices[0] and devList[2], resulting in the
UDL device being set up as a GPU device assigned to the first screen
instead of as a framebuffer on the third screen as the configuration
specified.
Checking Option "kmsdev" in code code may be a layering violation.
But the modesetting driver is actually part of the Xorg sources
instead of being an external driver, so he "kmsdev" path knowledge
may be used here.
