#1 doesn't happen to be always the case, most of the times the desktop become unusuable.
Anyway, with further testing I updated the bug. Looks like related to the X server settings. Opening it TWICE after selecting the NVIDIA card from intel, triggers this behavior. ** Summary changed: - X.org freeze after selecting nvidia profile + X.org freeze after selecting nvidia profile on Plasma Desktop ** Description changed: - - Using ubuntu 18.04.2 LTS. + - Using ubuntu 18.04.2 LTS, also tried 19.10 development eoan edition. - Tried driver NVIDIA 390 + 430 from the repo, same result - - KDE Plasma desktop + - Happens only on KDE Plasma desktop + - Does not happen on GNOME desktop + - Used the X server settings instead of the CLI Reproducibility: 75% Steps required: - Installing nvidia drivers on an optimus laptop - Rebooting - Select NVIDIA GPU with prime from Intel - Waiting some seconds + - Opening NVIDIA X server settings again, increases a lot the chance of the freeze to happen (looks like it gets the nvidia module loaded even before the session logout) - 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 + 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 (checked from a tty), 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? + Notes: If the session ends (doing a logout so SDDM) before the nvidia + module gets loaded, there is no lockup at all, but once the nvidia + driver is loaded, it looks like it's when the issue appears. ** Description changed: - Using ubuntu 18.04.2 LTS, also tried 19.10 development eoan edition. - Tried driver NVIDIA 390 + 430 from the repo, same result - Happens only on KDE Plasma desktop - Does not happen on GNOME desktop - - Used the X server settings instead of the CLI + - Used the X server settings instead of the CLI Reproducibility: 75% Steps required: - Installing nvidia drivers on an optimus laptop - Rebooting - Select NVIDIA GPU with prime from Intel - Waiting some seconds - - Opening NVIDIA X server settings again, increases a lot the chance of the freeze to happen (looks like it gets the nvidia module loaded even before the session logout) + - Opening NVIDIA X server settings again TWICE, increases a lot the chance of the freeze to happen (looks like it gets the nvidia module loaded even before the session logout) 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 (checked from a tty), the X.org session locks up.
