Thank you very much for your suggestion #21, Traumflug. I read the issue you quoted and to be honest, I was quite disappointed in the responses so far.
The symptoms sound very similar to those I reported here. I compared the wayland packages on my desktop (slow or lost mouse and keyboard events) with those on my laptop (ubuntu studio), which works satisfactorily. I will attach a file containing the two dpkg lists for comparison. I really don't understand the wayland architecture, but was happy to use the recommended workaround when running sudo gui programs such as gparted. I notice two differences and wonder whether either of them might account for the diference between my two systems? 1. The desktop has three i386 old packages not installed on the laptop. Perhaps I should delete them? 2. The desktop has the xwayland package installed, but the laptop does not. What do you think? Is this helpful in tracking down the root cause of the problem? Is there anything I can do to assist with further diagnosis, given I have two systems side-by-side for comparison? ** Attachment added: "dpkg list comparison for wayland" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1838919/+attachment/5282468/+files/2019-08-14-wayland-packages-compared -- 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/1838919 Title: Slow and lost keyboard and mouse events To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1838919/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
