I've been informed that this is a duplicate of 1805873 and that further communication about this bug should happen in this thread. I am able to reproduce this bug with a specific series of steps. Here's what I know:
--- I have a laptop and docking station with 2 displays attached. I can trigger a crash of the Xorg desktop by the following series of steps. Actual Behavior: 1. While the laptop is on the dock, put it to sleep 2. Pick up the laptop from the dock 3. Wake up the laptop while undocked 4. Use xrandr commands to adjust the laptops screen so it is the primary display 5. Put the laptop back to sleep 6. Re-dock the laptop 7. Wake up the laptop on the dock 8. Observe that Xorg has crashed, desktop state is lost, and the laptop has returned to the login screen. Expected Behavior: These is no combination of docking, sleeping, or xrandr display commands that can crash my X session and drop my laptop back to the login screen. Notes on Timing of this Issue: I've been living with this issue for many months, but it's only recently that I've realized that I can trigger it 100% of the time by running xrandr commands while undocked, then re-docking. This pattern is common if you use your laptop for work, taking it back and forth between the dock and various meeting rooms, then back to the dock again. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1787332 Title: Xorg crashed with SIGABRT in OsAbort() from AbortServer() from FatalError() from xf86VTEnter() from systemd_logind_vtenter() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1787332/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
