[SOLVED] Second monitor stopped working. nVidia KDE

I'm using laptop with RTX 2060, nvidia-open drivers ver. 560.35.03-6 and optimus-manager. Till today my second display was working just fine but when I started my computer this morning it just isn't detected. The problem is present in both X11 and Wayland KDE sessions. I'm not sure what outputs do you need to diagnose the issue, so I'll put here some I think might be helpful.

glxinfo | grep server                 

server glx vendor string: SGI
server glx version string: 1.4
server glx extensions:

lsmod | grep nvidia

nvidia_modeset       1957888  4
nvidia_uvm           6868992  0
nvidia              11169792  60 nvidia_uvm,nvidia_modeset
i2c_nvidia_gpu         12288  0
video                  81920  2 i915,nvidia_modeset

It seems, that just when I was righting this post an update came for optimus-manager. Now all is working fine.

Generally a RTX 2060 does not require optimus-manager and you could remove it and simply opt for https://wiki.archlinux.org/title/PRIME# … er_offload
