I've seen a couple of people report issues with manual NVIDIA driver installations recently but so long as you installed the NVIDIA driver through the 'Additional Drivers' app then it is expected to work.
I think I ran out of ideas for this bug a month ago but it does seem to be assigned to the wrong project so I shall change that. ** Package changed: xorg-server (Ubuntu) => nvidia-graphics-drivers-460 (Ubuntu) ** Also affects: linux-hwe-5.8 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to nvidia-graphics-drivers-460 in Ubuntu. https://bugs.launchpad.net/bugs/1919093 Title: [ThinkPad P1 Gen 3 w/ Intel + Nvidia Quadro T2000] Desktop does not load after login - purple screen with mouse Status in linux-hwe-5.8 package in Ubuntu: New Status in nvidia-graphics-drivers-460 package in Ubuntu: New Bug description: When logging in, the screen goes purple and blank, but I can still move the mouse. Keyboard shortcuts such as Alt+F2 or Ctrl+Alt+T have no effect. I can use Ctrl+Alt+F[1345...] to switch to a shell or go back to the login screen, but Ctrl+Alt+F2 puts me back in the blank state. When turning off the computer from the login screen, I get a warning that my user is logged in. The most similar previous bug report I've been able to find is https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1766137. However, my problem occurs regardless of whether I fail the first login attempt or not, or whether I enter my password or scan my fingerprint. I have replicated the problem booting with two kernel versions: Linux 5.8.0-44 and Linux 5.8.0-43 I have been using the computer since November 2020, and this problem occurred for the first time when I rebooted it this weekend (Sat 2021-03-13). I have previously had trouble getting getting external monitors to work, but even that has worked fine for the past few months.
