xorg.conf
Not quite sure this problem related to mesa.
Env:
linux kernel: 2.6.28.9
OpenGL renderer string: Mesa DRI Intel(R) 965GM GEM 20090114 x86/MMX/SSE2
OpenGL version string: 2.1 Mesa 7.6-devel // until some commit at Apr.14
xf86-intel-video: // until some commit at Apr.14
Xserver: X.Org X Server 1.6.1
xrandr: latest for git respority
Description:
An application use opengl render video stream, 25fps.
When doing something like switch monitor using xrandr, or upload RGBA texel.
Will cause application exit. And it hard to reproduce, need a few day or even a
week to trigger. Because appliction begin to run when system startup, Xserver
output may omit. Have ever saw something like:
X Error of failed request: BadRegion.
After add hooker to exit(), and backtrace, get following info:
...
0xb76848c9 in exit () from /lib/libc.so.6
0xb72f5b00 in _XDefaultError () from /opt/xorg/lib/libX11.so.6
0xb72f5bd3 in _XError () from /opt/xorg/lib/libX11.so.6
0xb72fcb1a in process_responses () from /opt/xorg/lib/libX11.so.6
0xb72fd145 in _XReply () from /opt/xorg/lib/libX11.so.6
0xb78e2b11 in DRI2CopyRegion () from /opt/xorg/lib/libGL.so.1
0xb78e27fc in dri2CopySubBuffer () from /opt/xorg/lib/libGL.so.1
0xb78e2855 in dri2SwapBuffers () from /opt/xorg/lib/libGL.so.1
0xb78bdcfb in glXSwapBuffers () from /opt/xorg/lib/libGL.so.1
0xb7874121 in glutSwapBuffers () from /opt/xorg/lib/libglut.so.3
...
After check the code, I think it maybe relate to mesa or Xserver.
If need more information. Please let me know.
Thanks all.
