NOTE: Results w/ haveged installed... I installed gdm3 3.28.0-ubuntu1 with:
apt-get install gdm3=3.28.0-0ubuntu1 libgdm1=3.28.0-0ubuntu1 gir1.2-gdm-1.0=3.28.0-0ubuntu1 After reboot gdm3 would still not start. After I noticed the path used I decided to: rm -rf /var/lib/gdm3/* rm -rf /var/lib/gdm3/.[a-z]* After a reboot gdm3 started both w/ Xwayland and Xorg It seems that the upgrade to kernel 4.15.0-24 together w/ gdm3 upgrade caused some corruption of the gdm3 cached contents under /var/lib/gdm3 that prevented it from starting. IMO this is not an easy thing to troubleshoot as nothing in the logs indicated any issue. It is could also be preventable: have the gdm3 package always clear /var/lib/gdm3 as the next start will recreate. As it stands now, my issue of gdm3 not starting is resolved, the haveged/entropy dependency is properly tracked by bug 1779827. Leave it up to you whether you want to use this bug to improve the gdm3 upgrade process or close it as I documented how I fixed it -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
