Public bug reported: - Using ubuntu 18.04.2 LTS. - Tried driver NVIDIA 390 + 430 from the repo, same result - KDE Plasma desktop
Reproducibility: 75% Steps required: - Installing nvidia drivers on an optimus laptop - Rebooting - Select NVIDIA GPU with prime from Intel - Waiting some seconds Bug observed: - Before the nvidia module gets loaded (I could type lsmod | grep nvidia fine and no module is loaded after the first 3 seconds) - When (presumably) the nvidia driver is loaded, the X.org session locks up. The mouse cursor can move things, but cannot click anything, everything else on the screen is frozen up Workaround: Killing the X.org session gives an usable graphical system Notes: If the session ends (doing a logout so SDDM) there is no lockup at all, but once the nvidia driver is loaded, it looks like it's when the issue appears. I recently moved from 19.04 to 18.04.2 LTS, and I don't remember this issue happening at all, is that some fix that needs to be backported? ** Affects: nvidia-prime (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1832145 Title: X.org freeze after selecting nvidia profile To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-prime/+bug/1832145/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
