I don't see a way to refile this post under a different project, but it probably belongs under xserver-xorg and possibly under xserver-xorg- input-wacom.
I've resolved my personal issue to my own satisfaction, although I'm not sure that xorg should segfault on this particular issue. The key to the puzzle came with a more extensive problem description in apport, which I tried to submit but didn't succeed. In any case, part of the apport response discussed that it was trying to remove the Wacom device. That convinced me that Qt, which I was previously staring very hard at, was not the problem and that I should check on the Wacom settings in my xorg.conf file. When those were removed, two things happened: (1) GTK programs did indeed start again; (2) my tablet input device still worked, as if by magic. (It didn't before I put those lines there!) So, to place the bug more narrowly: there were some recent patches in xserver-xorg-input-wacom. I believe that one of these patches automatically configures the tablet device for you -- a process that previously had to be done manually in xorg.conf. If the xorg.conf file specifies a manual configuration, apparently everything goes smooth for most applications, but GTK for some reason tries to remove the device and/or create a new one -- the details aren't clear to me. When the device gets removed and then recreated, Xorg apparently gets confused and segfaults. I have the feeling that not all of that is right, but in any case: something weird is happening that probably shouldn't be happening, even though the userbase it affects is probably a fringe case. -- Wacom + GTK + old configuration causes Xorg to segfault with error 4 under Kubuntu Jaunty https://bugs.launchpad.net/bugs/359133 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
