I tried the 'sudo ubuntu-drivers autoinstall' recommendation from the thread that was linked here, but it didn't work in my case.
The behaviour is erratic. Sometimes a reboot would help, though mostly not. Sometimes the applications bar is responsive (can start applications), other times it's not. Sometimes the items on the Desktop are clickable, other times not. One interesting behaviour I noticed once (though was not able to repeat) was that I had two partially overlapping windows with a file manager (Thunar), and the click events seem to go to the window that was UNDER (I could see the files being selected and could start them) - like the window on top was "transparent" to click events. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1730174 Title: [artful] Mouse broken after upgrade from 17.04 to 17.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/im-config/+bug/1730174/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
