I am running KDE Neon 20.04 with plasma 5.20.5. Yesterday driver 455.45.01 became available in my distro. I was running 455.38 previously without any issues. The upgrade to 455.45.01 bricked my OS. I couldn’t even boot into it in recovery mode. I’d select the os in Grub, it would then show my computer’s manufacturer logo, and then it would just show a black screen. I couldn’t get into another tty with Ctrl+Alt+F(1-6). There was no way to get to a terminal of any kind. So I reinstalled my OS, let it do its updates, and then had it install the nvidia driver. Same thing. So I tried doing it all over again on Kernel 5.9 instead of the default 220.127.116.11 since 455.45.01 says it has 5.9 support. Same thing happened there. Then I tried installing 455.38 that was working previously - but had no luck getting it to work outside of my distro package manager (I installed it from the download on nvidia.com). The only way for me to get nvidia drivers working now is to use 450 from my package manager. That is outdated, and the OS doesn’t display correctly - lots of scaling issues.
Does anyone have any suggestions on what is going wrong with the 455.45.01 update? Any help would be greatly appreciated.
