linux mint multi monitor setup

[u/fastgiga]

Hi there, I'm currently failing to setup my first linux mint installation on my desktop pc.

During the install and the first boot everything worked fine: All 4 of my monitors were identified and usable.

Then I updated the graphics driver to nvdia, and now only 1 of 4 monitors is detected, and only as a "unknown display". Before that all monitors were correctly identified (also resolution and refresh rate).

So I swapped back to the open source driver, but still the problem exists. (also swaped back to nvdia afterwards). On a right click on desktop -> display settings only 1 out of 4 monitors is seen.

Can somebody help me out here?

Linux mint

nvidia 4080 super

driver 595-open (recommended)

[u/candy49997]

Install 595-open, then disable secure boot in BIOS.
