Well what do you want me to backtrace exactly ? X is not crashed or freezed. It is only the display that is not showing anything. Reproducing it several times I have this morning for example a completly red screen.
If I switch to console mode then to X, KDM will be displayed correctly. It seems to be a problem when switching from bootsplash to X. And it seems random so maybe time dependent. The bt when X is in this state is the following : (gdb) bt full #0 0xb7f69410 in __kernel_vsyscall () No symbol table info available. #1 0xb7db184d in select () from /lib/tls/i686/cmov/libc.so.6 No symbol table info available. #2 0x081b2275 in WaitForSomething (pClientsReady=0xbfaf56d0) at ../../os/WaitFor.c:236 i = <value optimized out> waittime = {tv_sec = 0, tv_usec = 288000} wt = (struct timeval *) 0xbfaf5690 timeout = <value optimized out> clientsReadable = {fds_bits = {0 <repeats 32 times>}} clientsWritable = {fds_bits = {138251984, 136421032, -1079028280, 134814362, 136163204, 138227056, -1079028280, 135624344, 138251984, 138235008, -1079028264, 136163204, 136163204, 0, -1079028232, 135625376, 138227056, -1079028240, -1079028200, 135595231, 136340232, 136630248, 0, 136163204, 64, 138143360, -1079028152, 135639632, 138227056, 64, -1079028168, 4096}} curclient = <value optimized out> selecterr = 0 nready = <value optimized out> devicesReadable = {fds_bits = {138234856, 0, -1079028440, 136022337, 138234856, 136163204, -1079028408, 135452948, 138234856, -1209872396, -1209867936, 138251984, -1079028360, -1210772240, -1209867936, 138251984, 138234856, 4194537, 138234872, 138251976, 136163204, 138234872, -1079028344, 136163204, 138251984, 138227056, -1079028344, 136022337, 138251984, 136163204, -1079028312, 135452948}} now = 166232 someReady = 0 #3 0x0808d69d in Dispatch () at ../../dix/dispatch.c:425 result = <value optimized out> client = (ClientPtr) 0x837d470 nready = -1 start_tick = 0 #4 0x0807471b in main (argc=8, argv=0xbfaf5c04, envp=0x0) at ../../dix/main.c:452 i = 1 error = 136163204 xauthfile = <value optimized out> alwaysCheckForInput = {0, 1} (gdb) -- [hardy] Blank screen when starting the system after shutdown https://bugs.launchpad.net/bugs/126931 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
