Ville Syrjälä dcf8371a81 present: Walk all children when setting window pixmaps 
We currently skip setting the window pixmap on any window
not using its parent's pixmap. That does not work correctly
in the presence of reparenting.

Consider the following scenario:
1. window A is created as child of B
2. present starts flipping and sets the whole window
   tree to use pixmap X
3. window C is created (uses the screen pixmap by default)
4. window A is reparented to C
5. present stops flipping and attempts to set the
   whole window tree back to the screen pixmap,
   except the walk terminates at window C
   since it's using an unexpected pixmap, and
   window A is left with the stale pixmap X
6. pixmap X is destroyed
7. the X server segfaults on a rendering operation
   on window A due the stale pixmap

I managed to hit this with mpv (doing present flips)
and crack-attack (keeps alternating between a menu
window and an actual game window):
1. start both applications
2. start a game in crack-attack
3. fullscreen mpv
4. end the game in crack attack
5. unfullscreen mpv
6. the crack-attack menu window has appeared, but
   might be corrupted and doing stuff on it segfaults
   the X server

I suppose the other option might be to make new windows
automatically inherit their parent's pixmap instead
of using the screen pixmap. But I've not looked into
how that would affect eg. composite.

XLibre Xserver

Xlibre is a fork of the Xorg Xserver with lots of code cleanups and enhanced functionality.

This fork was necessary since toxic elements within Xorg projects, moles from BigTech, are boycotting any substantial work on Xorg, in order to destroy the project, to eliminate competition of their own products. Classic "embrace, extend, extinguish" tactics.

Right after journalists first began covering the planned fork Xlibre, on June 6th 2025, Redhat employees started a purge on the Xlibre founder's GitLab account on freedesktop.org: deleted the git repo, tickets, merge requests, etc, and so fired the shot that the whole world heard.

This is an independent project, not at all affiliated with BigTech or any of their subsidiaries or tax evasion tools, nor any political activists groups, state actors, etc. It's explicitly free of any "DEI" or similar discriminatory policies. Anybody who's treating others nicely is welcomed.

It doesn't matter which country you're coming from, your political views, your race, your sex, your age, your food menu, whether you wear boots or heels, whether you're furry or fairy, Conan or McKay, comic character, a small furry creature from Alpha Centauri, or just a boring average person. Anybody who's interested in bringing X forward is welcome.

Together we'll make X great again!

Upgrade notice

  • Module ABIs have changed - drivers MUST be recompiled against this Xserver version, otherwise the Xserver can crash or fail to start up correctly.

  • If your console is locked up (no input possible, not even VT switch), then most likely the input driver couldn't be loaded due to a version mismatch. When unsure, it's best to be prepared to ssh into your machine from another one or set a timer that's calling chvt 1 after certain time, so you don't need a cold reboot. Or, make sure that you have magic SysRq key enabled (Alt+PrtSc) via sysctl (kernel.sysrq=1), then press following combination depending on keyboard layout to make kernel regain control over keyboard to make VT switching work:

    • QWERTY/AZERTY keyboard layout: SysRq + R
    • Dvorak/Colemak keyboard layout: SysRq + P

  • Proprietary Nvidia drivers might break: they still haven't managed to do even simple cleanups to catch up with Xorg master for about a year. All attempts to get into direct mail contact have failed. We're trying to work around this, but cannot give any guarantees. But you can make it work by adding Option "IgnoreABI" "1" line to ServerFlags section in Xorg config.

  • Most Xorg drivers should run as-is (once recompiled!), with some exceptions. See .gitlab-ci.yml for the versions/branches built along with Xlibre.

Driver repositories

Since Redhat had deleted and banned all X11Libre repositories from freedesktop.org, the driver repositories are now moved to GitHub:
