I reinstalled 11.04 fresh in the hope that this was somehow related to the upgrade from 10.10, but no luck. I also switched to x86_64.
I do get a slightly different backtrace in Xorg.0.log now: Backtrace: [ 6735.877] 0: /usr/bin/X (xorg_backtrace+0x26) [0x4a2656] [ 6735.877] 1: /usr/bin/X (0x400000+0x621ca) [0x4621ca] [ 6735.877] 2: /lib/x86_64-linux-gnu/libpthread.so.0 (0x7fdf2f28a000+0xfc60) [0x7fdf2f299c60] [ 6735.877] 3: /usr/bin/X (0x400000+0x3d7e5) [0x43d7e5] [ 6735.877] 4: /usr/bin/X (ProcAllowEvents+0x14b) [0x43df1b] [ 6735.877] 5: /usr/bin/X (0x400000+0x2e2a9) [0x42e2a9] [ 6735.877] 6: /usr/bin/X (0x400000+0x21a7e) [0x421a7e] [ 6735.877] 7: /lib/x86_64-linux-gnu/libc.so.6 (__libc_start_main+0xff) [0x7fdf2e1d3eff] [ 6735.877] 8: /usr/bin/X (0x400000+0x21629) [0x421629] [ 6735.877] Segmentation fault at address 0x3ab81 I am still unable to provide a full backtrace.
