Yogish Kulkarni df6a3a07f6 Skip SetCursor when vtSema is FALSE. 
Consider below sequence -
1) Cursor is removed : isUp will be FALSE if HW cursor is set.
2) VT switched away from X : vtSema becomes FALSE.
3) xf86CursorSetCursor is called with non-null CursorPtr :
Saves the passed in CursorPtr, fallbacks to SW cursor and invokes
spriteFuncs->SetCursor which saves the area under cursor and restores
the cursor. This sets isUp to TRUE and as vtSema is FALSE saved data
is garbage.
4) VT switched to X : vtSema becomes TRUE. xf86Cursor enable fb access
is called which will remove the SW cursor, i.e copies saved data in #3
to screen.

This results to momentary garbage data on screen. Hence when !vtSema
skip spriteFuncs->SetCursor.

					X Server

The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.

Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the
following article:
http://en.wikipedia.org/wiki/X_server

All questions regarding this software should be directed at the
Xorg mailing list:
