That file (/etc/gdm3/custom.conf) doesn't exist on my system. I haven't been getting the popup for an error occurring today though. (The details in that dialog said it was a duplicate of this issue, which is how I found this)
I still have an issue where if I lock the screen it goes black with a blinking _ in the upper left. I can ssh in and reboot, but the UI is unresponsive no matter how long I wait (even Ctrl+Shift+F1-6 key combos do nothing). I'm not sure that is related, but the 'system error has occurred' dialog with this crash only happened after I did a reboot to get out of this. I'm going to do more debugging on this later this afternoon. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1543192 Title: Xorg crashed with SIGABRT in OsAbort() from AbortServer() from FatalError() from dix_main() ["no screens found"] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1543192/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
