I could narrow this bug with a 100% certitude (and confirm it also on Manjaro Linux on the same machine) with using the NVidia 304 proprietary driver.
My machine has a NVidia C77 [GeForce 8200] (rev a2) which is unsupported with latest NVidia 340 drivers (the system justs freezes). It used to work perrfectly using NVidia 304 "legacy" driver until upgrading to Ubuntu 17.10, but something must have recently changed in the way Gnome or Xorg handles the mouse and the legacy NVidia driver has probably not been updated, alas. THe bug does *NOT* exist when using the "nouveau" driver. Unfortunately, its doesn't perform as well as the proprietray NVidia did... But at least the mouse works again. -- 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/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/gnome-shell/+bug/1730174/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
