First, there's no need to run xfdesktop with sudo. You'll get the session warning because you aren't logged in as root so there's no session running for it.
>From the stack trace it, the only xfdesktop call in that stack is >xfdesktop_application_run (), which is located here: http://git.xfce.org/xfce/xfdesktop/tree/src/xfdesktop-application.c#n773 It's really hard for me to get that wrong! :) Is there anyway you can do a stack trace with the debug symbols installed? Maybe that will provide more detail to this bug. http://docs.xfce.org/contribute/bugs/start#backtraces May be of some help setting your system up for it. There's quite a few warning messages but luckily most of them have nothing to do with xfdesktop (seems to be vlc and libindicator don't get along well). GLib-GObject-CRITICAL **: g_value_get_uint: assertion `G_VALUE_HOLDS_UINT (value)' failed is interesting, maybe try running: xfdesktop --quit; xfdesktop --g-fatal-warnings If that warning message comes up then xfdesktop will crash, the backtrace from that may help pinpoint why that happens, but note that it probably won't help resolve this crash. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1358482 Title: xfdesktop crashed with SIGSEGV in XScreenCount() To manage notifications about this bug go to: https://bugs.launchpad.net/xfdesktop/+bug/1358482/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
