** Attachment added: "gnome-desktop_2.28.1-0ubuntu3.debdiff" http://launchpadlibrarian.net/34736555/gnome-desktop_2.28.1-0ubuntu3.debdiff ** Description changed: I just installed karmic on my freenx server machine when g-s-d starts it throws the following error: gnome-settings-daemon Xlib: extension "Generic Event Extension" missing on display ":1000.0". Xlib: extension "Generic Event Extension" missing on display ":1000.0". Xlib: extension "Generic Event Extension" missing on display ":1000.0". Xlib: extension "Generic Event Extension" missing on display ":1000.0". Xlib: extension "Generic Event Extension" missing on display ":1000.0". The program 'gnome-settings-daemon' received an X Window System error. This probably reflects a bug in the program. The error was 'BadRequest (invalid request code or no such operation)'. (Details: serial 105 error_code 1 request_code 150 minor_code 8) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) If I disable the xrandr plugin then the bug is not present (once bug 409621 is fixed). This is a regression from Jaunty where the xrandr plugin worked. I attach the the stack trace. If there is anything else I can do please let me know. ProblemType: Bug Architecture: amd64 Date: Sun Oct 18 17:10:18 2009 DistroRelease: Ubuntu 9.10 InstallationMedia: Ubuntu 9.10 "Karmic Koala" - Beta amd64 (20090929.2) NonfreeKernelModules: nvidia Package: libxrandr2 2:1.3.0-2 ProcEnviron: LANGUAGE=en_GB:en LANG=en_GB.UTF-8 SHELL=/bin/bash ProcVersionSignature: Ubuntu 2.6.31-14.48-generic SourcePackage: libxrandr Uname: Linux 2.6.31-14-generic x86_64 *** SRU stuff *** - Patch: http://launchpadlibrarian.net/34734843/gnome- + Patch: http://launchpadlibrarian.net/34736555/gnome- desktop_2.28.1-0ubuntu3.debdiff [Justification] gnome-settings-daemon crashes at startup on X servers which don't support RANDR 1.2. This is a regression from Jaunty [Description of patch] The patch just traps the BadRequest error generated from the unsupported X call in gnome-desktop, and sets a GError, allowing the calling application to handle it. [Test case] Run gnome-settings-daemon with each version of gnome-desktop. With gnome-desktop 2.28.1-0ubuntu2 - gnome-settings-daemon will crash With gnome-desktop 2.28.1-0ubuntu3 - gnome-settings-daemon will not crash [Regression risk] The regression risk is low, because: - gnome_rr_screen_new will now return a NULL GnomeRRScreen pointer and set a GError when called on servers that don't have RANDR 1.2 (as opposed to crashing). There are already other failure conditions in gnome_rr_screen_new which will return the same result, so this does not break API, and applications using it already handle the error properly (in the case of gnome-settings-daemon, the xrandr plugin just stops loading). - This technique for trapping errors was used previously. There were XRR calls in the Jaunty code which were only supported on RANDR >= 1.2. These were wrapped with gdk_error_trap_{push,pop} in Jaunty, but it seems this got omitted when the code was changed this cycle. -- The program 'gnome-settings-daemon' received an X Window System error. During on a FreeNX server suring a session. The crash does not happen when xrandr plugin is disabled. https://bugs.launchpad.net/bugs/454487 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
