Unfortunately it's not easy to replicate. I was able to see the crash in the xserver log as indicate below: <OL TYPE=1> Backtrace: </OL> <OL TYPE=1> 0: /usr/bin/X(xf86SigHandler+0x7e) [0x80c91ce] </OL> <OL TYPE=1> 1: [0xb7eef400] </OL> <OL TYPE=1> 2: /usr/lib/dri/r200_dri.so(_mesa_update_texture+0x276) [0xaed4ae76] </OL> <OL TYPE=1> 3: /usr/lib/dri/r200_dri.so(_mesa_update_state_locked+0x69a) [0xaed32c1a] </OL> <OL TYPE=1> 4: /usr/lib/dri/r200_dri.so(_mesa_update_state+0x2a) [0xaed32cfa] </OL> <OL TYPE=1> 5: /usr/lib/dri/r200_dri.so(_mesa_GetIntegerv+0x260) [0xaee11390] </OL> <OL TYPE=1> 6: /usr/lib/xorg/modules/extensions//libglx.so [0xb7b8e950] </OL> <OL TYPE=1> 7: /usr/lib/xorg/modules/extensions//libglx.so [0xb7b550ac] </OL> <OL TYPE=1> 8: /usr/lib/xorg/modules/extensions//libglx.so [0xb7b54727] </OL> <OL TYPE=1> 9: /usr/lib/xorg/modules/extensions//libglx.so [0xb7b590d6] </OL> <OL TYPE=1> 10: /usr/bin/X [0x8154bf4] </OL> <OL TYPE=1> 11: /usr/bin/X(Dispatch+0x314) [0x808de24] </OL> <OL TYPE=1> 12: /usr/bin/X(main+0x4b5) [0x8074795] </OL> <OL TYPE=1> 13: /lib/libc.so.6(__libc_start_main+0xe5) [0xb7cc1455] </OL> <OL TYPE=1> 14: /usr/bin/X(FontFileCompleteXLFD+0x21d) [0x8073a81] We are using ATI 9250 PCI based video cards. Those people not running Compiz never see this issue, it's definitely related to the 3D GNOME desktop.
