There is one more change I did after upgrading from 19.04 to 19.10. This is a KVM VM - and for some reason, the GUI (X) sometimes freezes after the VM is paused/saved/resumed, while SSH still works (this was also before 19.10 and behaviour did not improve in 19.10).
I've changed to Wayland to see if it this kind of freezing happens there as well (so far, it doesn't). High CPU usage on all cores happens with Wayland only. I've just checked, it doesn't happen with regular X; CPU usage is normal/low there. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1850874 Title: gnome-shell (via Mesa/LLVMpipe in a virtual machine) uses all CPU cores just to update the screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1850874/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
