** Description changed: Binary package hint: xorg I updated to the latest version of xorg yesterday ( may 18th 2011 ) - xserver-xorg 1:7.6+4ubuntu3.1 Now, opening any qt based application ( or after the interface is open, interacting with it ) crashes xorg, reboots and goes back to the login screen. There have been a few other random occasions where xorg restarted while invoking random programs ( like file manager ). + Backtrace: + [ 384.093] 0: /usr/bin/X (xorg_backtrace+0x3b) [0x80eab1b] + [ 384.093] 1: /usr/bin/X (0x8048000+0x5fac8) [0x80a7ac8] + [ 384.093] 2: (vdso) (__kernel_rt_sigreturn+0x0) [0x55f40c] + [ 384.094] 3: /usr/bin/X (ProcessWorkQueue+0x30) [0x80748c0] + [ 384.094] 4: /usr/bin/X (WaitForSomething+0x60) [0x80a1de0] + [ 384.094] 5: /usr/bin/X (0x8048000+0x27f1e) [0x806ff1e] + [ 384.094] 6: /usr/bin/X (0x8048000+0x1a81c) [0x806281c] + [ 384.094] 7: /lib/i386-linux-gnu/libc.so.6 (__libc_start_main+0xe7) [0x3b5e37] + [ 384.094] 8: /usr/bin/X (0x8048000+0x1a411) [0x8062411] + [ 384.094] Segmentation fault at address (nil) + [ 384.094] + Caught signal 11 (Segmentation fault).
