I've been trying to avoid this, but as long as I had a crash today, I decided to get more data. I can consistently reproduce the crash by starting X, starting 5 urxvt windows, then rapidly moving windows around with H-arrow keys. It takes maybe 15 seconds to trigger the bug in most cases.
But first, I attached gdb. I'll attach the full log momentarily, but here is the traceback it found: 0x000000000043d7e5 in PlayReleasedEvents () at ../../dix/events.c:1188 in ../../dix/events.c #0 0x000000000043d7e5 in PlayReleasedEvents () at ../../dix/events.c:1188 prev = <value optimized out> qe = 0x30d15f0 dev = <value optimized out> pDev = <value optimized out> #1 ComputeFreezes () at ../../dix/events.c:1385 replayDev = <value optimized out> w = <value optimized out> grab = <value optimized out> dev = <value optimized out> #2 0x000000000043df1b in ProcAllowEvents (client=0x2f913e0) at ../../dix/events.c:1846 time = {months = 0, milliseconds = 1161414} mouse = 0x2cf4dc0 keybd = <value optimized out> stuff = 0x304b590 #3 0x000000000042e2a9 in Dispatch () at ../../dix/dispatch.c:431 clientReady = 0x2e77e40 result = <value optimized out> client = 0x2f913e0 nready = 0 icheck = 0x7f1410 start_tick = 120 #4 0x0000000000421a7e in main (argc=6, argv=<value optimized out>, envp=<value optimized out>) at ../../dix/main.c:287 i = <value optimized out> alwaysCheckForInput = {0, 1} -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/780961 Title: Natty Xorg crashes on Thinkpad X201 (i915 driver) when using keyboard- based window management To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/780961/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
