[Bug 1820031] Re: My Ubuntu 18.04 GUI seems frozen
the kernel driver "crashed", which is why the screen froze You could try booting with i915.enable_ppgtt=0 to see if the bug goes away, or a newer kernel. 4.18 is available via 'linux-image-generic- hwe-18.04'. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1820031 Title: My Ubuntu 18.04 GUI seems frozen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1820031/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Nothing new comes out in the crash report. When I visit https://errors.ubuntu.com/user/1d81a00d35531ca846cc8b470c853c9c4cc299c3a0a42040e68da92210168a3d96818f5de95d8f7d85e66516d77e481a6259123145189d1685f6d22ac584114a the most recent report is: https://errors.ubuntu.com/oops/0d2b0694-2b7d-11e9-9d81-fa163e102db1 I shall try to apply the work around from https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/994921 as suggested in step 3 of the instructions you have linked to. I do not need to apply it as it is already in place. So what next... apport-collect perhapse although it seems that enough debug may be already posted. Maybe just a reboot of my system (as I cannot restart a service) and move on. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1820031 Title: My Ubuntu 18.04 GUI seems frozen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1820031/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1820031] Re: My Ubuntu 18.04 GUI seems frozen
Assuming your GUI is Gnome Shell, please... 1. Log in via SSH while the GUI is still frozen. 2. Run: killall -ABRT gnome-shell 3. Follow these instructions: https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment However if that all doesn't work then don't panic.
