recipes/xorg-xserver/xserver-xorg-1.10.1.902/hack-fbdev-ignore-return-mode.patch

   1 Ugly hack that prevents server termination with xf86-video-fbdev-0.4.1
   2 (and probably other) while returning from chvt or resume on some
   3 hardware (e. g. zaurus).
   4
   5 Correct fix would require debugging of fbdev mode during LeaveVT and
   6 EnterVT.
   7
   8 This patch may cause staying in incorrect or corrupted display mode
   9 after EnterVT, but on man affected devices it does not cause any visible
  10 problems.
  11
  12 Hacked code is never called on properly written drivers.
  13
  14 Devices affected and testers involved for future patch removal:
  15 Sharp Zaurus (spitz/akita): Stanislav Brabec <utx@penguin.cz>
