I accidentally updated my NVIDIA drivers with apt. After reinstalling the old version (410) I end up in a command line login. Here is everything fine and nvidia-smi says that driver and cuda are installed properly.
When I startx I get my desktop, but mouse and keyboard don't work. Means my keyboard works in tty but not in X.
Has anyone an idea, how I could get my desktop back?
OS: Kubuntu 18.04
GPU: NVIDIA RTX 2080 Ti

To be honest for now I would be happy to have a working desktop with the nouveau driver so that I can reinstall the NVIDIA drivers on top of the working system. – Meredith Hesketh Fortescue Sep 11 '19 at 14:37Nvidiadrivers using CLI? – Yaron Sep 12 '19 at 11:29
