Re: updated logs - I did a fresh Kubuntu 20.04 install to USB stick (NOTE: 'Download Updates' and 'Install Third Party Drivers' selected via installer), rebooted, and was greeted by black screen, as per original bug issue.
The Nvidia drivers were again installed that have issues. So possibly buggy/incomplete nvidia drivers, but ubuntu-drivers was still 'aware' of issues: " root@xxxubuntu-drivers list ERROR:root:No "nvidia-dkms-340" can be found. nvidia-340 " I also did "apt-get update && apt-get upgrade" which upgraded a lot of things, but reboot has no change to black screen. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to ubuntu-drivers-common in Ubuntu. https://bugs.launchpad.net/bugs/1882402 Title: Ubuntu-drivers allows installation of (nvidia-340) drivers, which are broken/break things (Kubuntu 20.04) Status in ubuntu-drivers-common package in Ubuntu: Incomplete Bug description: Ubuntu-drivers allows installation of (nvidia-340) drivers, which are broken/break things.
