@smustgrave and @ariake - I've attempted to cover some of the other suspend issues I found whilst trying to work out where my machine was going wrong in the first post here - https://ubuntuforums.org/showthread.php?t=2395562
The XPS is tricky because there were some XPS suspend issues related to s2idle (https://askubuntu.com/questions/1029474/ubuntu-18-04-dell- xps13-9370-no-longer-suspends-on-lid-close/1036122#1036122) and it also has nVidia graphics which had a buggy nouveau driver (don't know if it's been fixed yet) or could be an issue with the proprietary drivers. s2idle issues and nVidia nouveau problem exhibited similar behaviour. I'll be happy to try to help troubleshoot over on the Ubuntu forum thread and hopefully you won't need the patched kernel to get suspend working properly again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1774950 Title: Suspend fails in Ubuntu and Kubuntu 18.04 but works fine in Ubuntu and Kubuntu 17.10 (and on Kubuntu 18.04 using kernel 4.14.47) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1774950/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
