Installed linux-headers-4.15.0-23-generic, now dkms runs properly. Re-tested w/ 4.15.0-23-generic: gdm3 STILL does not come up, just bounces between black screen and the systemd progress messages. So, going back to 4.15.0-23-generic does NOT solve the original issue.
I will continue w/ haveged and lightdm workaround, but the bug should remain open. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in Ubuntu. https://bugs.launchpad.net/bugs/1779476 Title: Ubuntu 18.04: gdm3 does not switch to graphics after update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1779476/+subscriptions -- desktop-bugs mailing list firstname.lastname@example.org https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
