Upgrading to (K)Ubuntu 18.04.5 LTS basically broke the system as X was not restarting correctly (black screen instead of lightdm display or even infinite loop of X crashes based on BIOS/EFI config).
This is critical for non-savvy users as my parents. The issue is the same as can be seen in /var/log/lightdm/seat0-greeter.log with repeated messages like **MEMORY-ERROR***: unity-greeter[1647]: GSlice: failed to allocate 2040 bytes (alignment: 2048)... **MEMORY-ERROR***: unity-greeter[1647]: GSlice: failed to allocate 2040 bytes (alignment: 2048)... **MEMORY-ERROR***: unity-greeter[1647]: GSlice: failed to allocate 2040 bytes (alignment: 2048)... The workaround is indded updating the memlock limits as described above (adding the 2 lines of the above comment to /etc/security/limits.con). Thanks for the workaround :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1662244 Title: lightdm causes all greeters to fail to start To manage notifications about this bug go to: https://bugs.launchpad.net/lightdm/+bug/1662244/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
