5697,Screen resolutions above 1600x1200 cause X in guest to crash in CentOS 5.3 amd64,Mike,,"Setting any video mode with a width of 1920 (1920x1200 or 1920x1080) causes X in the guest OS to crash.  I am unable to retrieve the Xorg.0.log file from the machine but I can see what appears to be a kernel crash on the console.

Host and guest are both CentOS 5.3 amd64.

I can see part of the stack trace from the crash.  It appears to go:

{{{

/usr/lib64/xorg/modules/libvbe.so

/usr/lib64/xorg/modules/libshadowfb.so
/usr/lib64/xorg/modules/libshadowfb.so

}}}

I'm sure there's more but it scrolls off the screen and I can't retrieve it.


Here is the xorg.conf I'm trying to use:
