Visual issues with triple monitor setup

Hello.

I just installed Garuda and I must say I really do love it. I am however experiencing some visual issues... I would attach a screenshot/image of what it looks like, but I cant as I'm new. So I uploaded it to imgur :slight_smile:

Screenshot of settings (expected result): https://i.imgur.com/d2IGYWb.png
Photo of setup (actual result): https://i.imgur.com/XPvCrAu.jpeg

The cursor does move as normal on the left monitor, but selecting seems to be inverted and half of the center monitor shows on it. As for the monitor on the right, it seems shaky/blurry. Also on the dark background it looks as if text is burned into the screen (its not).

A tricky monitor setup like this will not be plug-and-play, but you might be able to get there using just the GUI settings menu in KDE. Have you checked it out? What have you tried so far?

I think installing the proprietary drivers could help here, with the HW assistant (Garuda Welcome - > Garuda Settings Manager - > Hardware Configuration)
And then work also with nvidia-settings.

I tried this, but I had some issues...

Maybe I should add this, not sure if it's relevant but probably is

Also, 1 monitor is connected via gpu, the other 2 are connected to on board graphics. I wish it was different, but unfortunately thats the only way I could get this setup...

Here I think you can safely answer y instead of the default N.
Could you try again in this way?

How would I change this? I used the auto installer in the Hardware Configuration in the Garuda Settings Manager. I didn't see an option to change anything.

Install python-pyxdg (removing python-xdg when prompted) then try again.

Thanks, that fixed that part. However the other issue still remains and actually got slightly worse. The monitor on the right is still shaky/blurry but now the monitor on the left does not get detected at all. The monitor on the left is the only one that is connected to the graphics card, the other 2 are connected to on board graphics.

In meanwhile I had another issue as well, the dock was completely gone. But with help from this post I was able to fix that.
