http://bugzilla.novell.com/show_bug.cgi?id=533979 Summary: X server gets signal 11 when switching applications Classification: openSUSE Product: openSUSE 11.2 Version: Factory Platform: x86-64 OS/Version: SuSE Other Status: NEW Severity: Critical Priority: P5 - None Component: X.Org AssignedTo: bnc-team-xorg-bugs@forge.provo.novell.com ReportedBy: novell.com@christianmorlok.de QAContact: xorg-maintainer-bugs@forge.provo.novell.com Found By: --- Created an attachment (id=314983) --> (http://bugzilla.novell.com/attachment.cgi?id=314983) Xorg log with backtrace User-Agent: Mozilla/5.0 (compatible; Konqueror/3.5; Linux) KHTML/3.5.9 (like Gecko) I updated factory yesterday, now the X server crashed 2 times today. I can't reproduce it, but it seems to happen if I switch to an application that was not used a while, so it has to reload its buffer. The version I have installed: zypper wp xorg-x11-server Loading repository data... Reading installed packages...

I will install them and post a new Xorg.log the next time it crashes. Reproducible: Couldn't Reproduce Steps to Reproduce: 1. Open a lot of application 2. Switch from one app to another 3. crash Actual Results: X server crashes with signal 11 -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The two logs posted show crashes at totally different places. This could be an indication that something more fundamental is wrong. 3. Christian, why do you have the Xserver installed both for 32bit and 64bit? If this is a 64bit system, please uninstall the 32bit version. 4. To get a better backtrace (with debuginfo) one needs to use gdb. I've been using a script like: #!/bin/sh GDB=$HOME/gdb ARGS=$* cat > .dbgfile << "HERE" file /usr/bin/Xorg set args $ARGS handle SIGUSR1 nostop handle SIGUSR2 nostop handle SIGPIPE nostop run bt cont cont quit HERE $GDB -x .dbgfile &> /tmp/X.dgb.log which I've linked to /usr/bin/X to do that. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Right.

I don't think that there is a gdb in Christian's $HOME, but /usr/bin/gdb should work instead as long as gdb has been installed. Setting to NEEDINFO.

This was a cut-n-paste from a script that I had sitting around. IHMO we used to ship such a script in the past. However I wasn't able to find it any more.

It's still there and it's called xf86debug. Unfortunately it's only useful if the Xserver crashes immediately. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

OK, this should also do the job, it's missing the lines: handle SIGUSR2 nostop handle SIGPIPE nostop though. The latter one is rather important as we can easily get a SIGPIPE on X traffic. Christian, if you add those two lines you can also link this to /usr/bin/X. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I updated to the latest packages and used the gdb-script. I used this daily about a week but no crash happened.
