First to note that this is entirely consistent - it happens every time without fail. Also to say my laptop was stable using karmic, this problem appears to have started once I upgraded to lucid.
Bit more investigation. I have now installed the debug packages: xserver-xorg-video-radeon-dbg xserver-xorg-core-db libgl1-mesa-dri-dbg The trace now says: Backtrace: 0: /usr/bin/X (xorg_backtrace+0x3b) [0x80e937b] 1: /usr/bin/X (0x8048000+0x61c7d) [0x80a9c7d] 2: (vdso) (__kernel_rt_sigreturn+0x0) [0x94d410] 3: /usr/lib/xorg/modules/drivers/radeon_drv.so (0x4f5000+0xb2039) [0x5a7039] 4: /usr/lib/xorg/modules/libexa.so (0x18d000+0x9490) [0x196490] 5: /usr/lib/xorg/modules/libexa.so (0x18d000+0x9558) [0x196558] 6: /usr/bin/X (miCopyRegion+0x21b) [0x819cadb] 7: /usr/bin/X (miDoCopy+0x44d) [0x819cffd] 8: /usr/lib/xorg/modules/libexa.so (0x18d000+0x7a4a) [0x194a4a] 9: /usr/bin/X (0x8048000+0xda9c3) [0x81229c3] 10: /usr/bin/X (0x8048000+0x28df5) [0x8070df5] 11: /usr/bin/X (0x8048000+0x2a477) [0x8072477] 12: /usr/bin/X (0x8048000+0x1ed7a) [0x8066d7a] 13: /lib/tls/i686/cmov/libc.so.6 (__libc_start_main+0xe6) [0xa52bd6] 14: /usr/bin/X (0x8048000+0x1e961) [0x8066961] Segmentation fault at address (nil) Caught signal 11 (Segmentation fault).
