[SOLVED] monitors not detected properly

yonnieboy · 03-05-2024, 01:35 PM

I've got 3 monitors, all HMDI. They are connected to 3 ports on my new to me computer. All 3 monitors seem to display the same screen. The Display configuration shows only one monitor.
My OS is PCLOS version 2023 and DE is KDE.

Please show input/output from running in Konsole:

Code:

xrandr --listproviders
inxi -GSaz --vs

Go to Display Configuration in KDE settings and uncheck Unify Outputs. Some dragging of monitor outlines may be required.

Thank you for your patience. I have an image of display settings. There are no line drawing functions available and image uploader is missing

Incorrect; the paper-clip icon in the posting window is for attachments.

Did you read what lvm_ posted??? If all three screens are WORKING, you just have to use KDE settings to lay them out as you wish.

yonnieboy · 03-08-2024, 01:22 PM

KDE settings did not have lines for re-draw as only one monitor was detected onto the 3.

Ok! Got it working! I can't re-find what I toggled on as it's not there anymore. In computer configuration under graphical settings and way down the list was Xorg. I needed the amdgpu too! I had thought both were picked earlier. I had to go find a VGA cable as one of the monitors died during all of this. But thanks alot for all your patience!

To help us help you, whenever providing command output, to preserve the formatting that makes it readable and understandable, it should include the actual command that resulted in the output, just like it appeared on your display, and resemble what follows:

Code:
