External monitor suddenly not working anymore

Support Graphics & Display

So, from one day on another my external monitor is not working anymore. I’ve tried to fix it myself without much succes sadly enough. Since the nvidia drivers where N/A for my kernel 5.9 and mhwd couldn’t install drivers for it, I switched to 5.4 installed drivers. This didn’t work so I thought perhaps try it on 5.10 but now I can’t seem to reinstall the drivers (and I think these drivers are still for version 5.4 of the kernel).

I hope somebody can help me fix this. :slight_smile:

EDIT: so I tried this and struggled at bit but got this working HDMI not working on fresh install with Nvidia - #6 by XRaTiX. I also had to uncomment the wayland=false line. My “dash to dock” doesn’t seem to get visible if I swipe down though.
EDIT: dash to dock fixed although I first couldn’t find the name of this handy little thing.

QUESTION: How does it come that I suddenly have to use this optimus-manager while before I didn’t have to do anything?

Kind regards,
Joris
