@Tobins, can you please obtain a better stacktrace? To do that you need to add the ddebs repository. Basically, first add these lines into /etc/apt/sources.list:
deb http://ddebs.ubuntu.com jaunty main restricted universe multiverse deb http://ddebs.ubuntu.com jaunty-updates main restricted universe multiverse deb http://ddebs.ubuntu.com jaunty-security main restricted universe multiverse deb http://ddebs.ubuntu.com jaunty-proposed main restricted universe multiverse And then just run "sudo apt-get update". How to add ddebs debug symbols repository is explained in more detail here: https://wiki.ubuntu.com/DebuggingProgramCrash After you have activate the ddebs repository, please install this package: sudo apt-get install xserver-xorg-video-vesa-dbgsym Also, while you're add it please install these ones as well: sudo apt-get install xserver-xorg-core-dbg Once you got all the debug symbols installed please reproduce the crash again and then attach /var/log/Xorg.0.log and /var/log/Xorg.0.log.old This will hopefully give us function names for all the stackframes. --- For step #2 please use gdb to obtain a backtrace that includes all variables as well: https://wiki.ubuntu.com/X/Backtracing#Backtrace%20with%20gdb (the easiest way is to connect to this machine using ssh, then attach gdb to the X process, trigger the bug and finally run "backtrace full"). ** Changed in: xserver-xorg-video-vesa (Ubuntu) Status: New => Incomplete -- [vesa] "close" button in gnome-display-properties causes SEGV in X server https://bugs.launchpad.net/bugs/374507 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-vesa in ubuntu. _______________________________________________ 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
