Public bug reported: Binary package hint: xorg
Testing Lucid 10.04 LiveCD i386 for 2010-03-04 there is a continuation of an Xorg crash at log-in. The alpha-3 CD image didn't give any useful cause but the 2010-03-04 image does. GDM begins and starts the live user session which crashes almost immediately (sometimes the desktop background is shown briefly, but that is it). GDM then restarts and offers the log-in screen. To enable useful debugging the image is booted via PXE/NFS to capture netconsole kernel logging. opensssh-server is installed and an SSH session used to collect the log files. Xorg.0.log.old shows: ----- Backtrace: 0: /usr/bin/X (xorg_backtrace+0x3b) [0x80e880b] 1: /usr/bin/X (0x8048000+0x61aed) [0x80a9aed] 2: (vdso) (__kernel_rt_sigreturn+0x0) [0xb44410] 3: /usr/lib/libpixman-1.so.0 (0xd8d000+0x13a49) [0xda0a49] 4: /usr/lib/libpixman-1.so.0 (0xd8d000+0x39728) [0xdc6728] 5: /usr/lib/libpixman-1.so.0 (0xd8d000+0x414fa) [0xdce4fa] 6: /usr/lib/libpixman-1.so.0 (0xd8d000+0x4271a) [0xdcf71a] 7: /usr/lib/libpixman-1.so.0 (0xd8d000+0x393d3) [0xdc63d3] 8: /usr/lib/libpixman-1.so.0 (0xd8d000+0x145c3) [0xda15c3] 9: /usr/lib/libpixman-1.so.0 (0xd8d000+0x3b44e) [0xdc844e] 10: /usr/lib/libpixman-1.so.0 (0xd8d000+0x145c3) [0xda15c3] 11: /usr/lib/libpixman-1.so.0 (0xd8d000+0x46863) [0xdd3863] 12: /usr/lib/libpixman-1.so.0 (0xd8d000+0x145c3) [0xda15c3] 13: /usr/lib/libpixman-1.so.0 (pixman_image_composite+0x16f) [0xdc72cf] 14: /usr/lib/xorg/modules/libfb.so (fbComposite+0x1cc) [0x88b05c] 15: /usr/lib/xorg/modules/libxaa.so (XAAComposite+0x24c) [0xa13d4c] 16: /usr/lib/xorg/modules/libxaa.so (0x9e3000+0x4d3e0) [0xa303e0] 17: /usr/bin/X (0x8048000+0xd7e0b) [0x811fe0b] 18: /usr/bin/X (CompositePicture+0x298) [0x8113118] 19: /usr/bin/X (0x8048000+0xd11dd) [0x81191dd] 20: /usr/bin/X (0x8048000+0xcdeb3) [0x8115eb3] 21: /usr/bin/X (0x8048000+0x2a457) [0x8072457] 22: /usr/bin/X (0x8048000+0x1ed3a) [0x8066d3a] 23: /lib/tls/i686/cmov/libc.so.6 (__libc_start_main+0xe6) [0x2bdbd6] 24: /usr/bin/X (0x8048000+0x1e921) [0x8066921] Segmentation fault at address (nil) Caught signal 11 (Segmentation fault).
