I couldn't upload the crash file _usr_lib_xorg_Xorg.0.crash, because ubuntu-bug wants to open a web browser, which is obviously not possible when X11 is not available.
Through an "ssh -Y" session, I got a window with the following error message : Sorry, Ubuntu 18.10 has experienced an internal error. If you notice further problems, try restarting the computer. And in the terminal : QPainter::begin: Paint device returned engine == 0, type: 2 QPainter::end: Painter not active, aborted I was able to run an XTerm window through the same connection. I've launched apport-bug without arguments, and it uploaded all information it could in bug #1803123 apport-bug was nice enough to show an URL to work with uploaded data. It would be nice if ubuntu-bug could do the same when uploading a crash file ! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1802950 Title: X.org crashes after upgrade to 18.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1802950/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
