This bug is closed for now because the information requested in comment #2 was not provided.
I'd like to note though, that if you find 'swapoff -a' helps then that's an indication your system was experiencing a memory leak. For some reason Ubuntu is better able to deal with those situations when swapping is disabled. But it doesn't mean the kernel's swapping behaviour is the main issue... If you would like to continue discussing this bug then please: (a) Provide the information requested in comment #2; and (b) Reproduce the lag situation again and while it is happening run: ps auxw --sort -rss > allprocesses.txt and then attach the file 'allproceses.txt' here. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1855469 Title: gnome-shell lags on wayland To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1855469/+subscriptions -- desktop-bugs mailing list firstname.lastname@example.org https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
