[Bug 774978] Re: xserver seg'd [945GM]
Another me too. Sorry, I only have the segfaults that were recorded in my Xorg logs; 3 of them in short succession. My 945GM laptop has been suffering from unpredictable hangs ever since upgrading to 11.04 (32-bit), which might be related. The 3 segfaults all happened within a very short period of each other and I haven't been able to reproduce them subsequently. I dropped back to the old kernel (2.6.35-22-generic) after the 2nd one and the same thing happened. I note that Bryce said the Xorg logged backtraces aren't of any use. However, as well as the daily lockup incidents and the short burst of 3 segfaults, I also see occasional rendering artefacts when using gedit. Could all these be related? The system was very stable before the upgrade. The most repeatable thing I could try to debug is the lockups. Can anyone tell me how to do that?

[Bug 774978] Re: xserver seg'd [945GM]
Marcelo, the record extension will still be loaded indeed. However, without synaptics the extension is not activated. You can check this by attaching gdb to Xorg (from a second pc) and setting a breakpoint on RecordAReply. If the breakpoint is hit, record is active. With synaptics installed (on a pc with a touchpad, so synaptics is actually used) you will see the breakpoint is hit, without synaptics it is not hit. Btw, my current fix/workaround is to build synaptics without record support, by dropping the libxtst-dev build-dependency. This way the touchpad is working properly and X does not crash. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/774978 Title: xserver seg'd [945GM] -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 774978] Re: xserver seg'd [945GM]
I have tried running X under strace, but no success. I couldn't reproduce the crash, probably because X became too slow. Log file when calibre was running was 5 GB. I also tried xtrace and valgrind without luck. xtrace only showed what calibre was doing. Valgrind shows errors, but only before and right after login. Also, with valgrind I couldn't reproduce the crash, as X was very slow again. Then I enabled additional debugging in X by defining DEBUG_COMMUNICATION (in os/io.c). I added the requestbuffer address, request name and event name to the debugging output. The attached log looks interesting to me. Right before the crash we see the same requestbuffer is used by 2 different clients: [ 11518.727] REQUEST: ClientIDX: 6, type: 0x89 data: 0xa len: 8 buffer: 0x7f3071065010 name: DRI2 [ 11518.729] REQUEST: ClientIDX: 32, type: 0x35 data: 0x18 len: 4 buffer: 0x7f3071065010 name: CreatePixmap [ 11518.746] REPLY: ClientIDX: 6 buffer: 0x7f3071065010 Xreply: type: 0x1 data: 0xff len: 0 seq#: 0x1802 [ 11518.747] Segmentation fault at address 0x7f3071065010 (clientidx 32 is calibre, clientidx 6 is most likely compiz) As RecordAReply uses the requestbuffer to find the details of the DRI2 request, this looks very suspicious to me. ** Attachment added: Xorg.0.log (8 MB) https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/774978/+attachment/2117464/+files/Xorg.log.debug3 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/774978 Title: xserver seg'd [945GM] -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Looks similar to bug #525066 but I wasn't able to trigger this using vnc. Steps to reproduce this crash would be very helpful. I have some theories why it's crashing but would need to tinker with it locally to figure it out. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/774978 Title: xserver seg'd [945GM] -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Alternatively, try launching Xorg on the server with strace and collect the last hundred lines of output.

@Ken, Hmm, that website works for me on rv770 without crashing X, but I only poked at it for a minute or so. How much time does it seem to take you from landing on the page to the crash? Does it occur on the main page (which I note has lots of flash), or after navigating to sub-pages? Any particular page that crashes more often than the others? I note this url has lots of flash on it, as mentioned in the original report. Anything else unusual about your system beyond stock, that could help us replicate the crash? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/774978 Title: xserver seg'd [945GM] -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
