[Bug 1775593] Re: X server crashes with SIGBUS when resuming from suspend
Dummy me, forgive me: I still had the crash file around, it was just a question of giving read permission to everyone (since it was only readable by root and group whoopsie), and running ubuntu-bug over it. So, after changing problem_types in /etc/apport/crashdb.conf to: 'problem_types': ['Bug', 'Package', 'Crash'], and running: ubuntu-bug /var/crash/_usr_lib_xorg_Xorg.0.crash The new bug is bug #1775790. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1775593 Title: X server crashes with SIGBUS when resuming from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1775593/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thanks for the swift feedback. I had tried to run: ubuntu-bug /var/crash/FILE.crash but it complained of lack of permission. I wasn't aware of the workaround of bug #994921.
