Ubuntu started to freeze when external monitor is connected. It happened after update to nvidia-driver-465 and also the same behaviour on nvidia-driver-460.
When starting Ubuntu without connected monitor it works good but when i’m connecting it, the screen freezes and only cursor is available, even can’t get a terminal opened. Also when starting with connected monitor it shows the black screens only.
Found something in kern.log that could help kern.log (20.1 KB)
Seeing the same issue on my desktop machine –
Driver: nvidia-driver-460 version 460.80-0ubuntu0.20.04.1
OS: Ubuntu 20.04.2 LTS
Processor: AMD Ryzen 9 3950x
Graphics: Geforce RTX 2080 Ti
Installing the latest nvidia-driver-460-server package (460.73.01-0ubuntu0.20.04.1) resolved the issue for me.
Thank you guys, like a temporary solution I’ve rolled back my nvidia driver to 460.73 then.
Yesterday tried to update to 470.57.02 and it worked, but today i realized that these drivers just switched off or something like that (and i didn’t manage to switch them on), so i decided to install them via running ubuntu-drivers autoinstall and now all is perfect but in NVIDIA (Performance Mode) PRIME profile only.
