Hello. I’m using Fedora 42, KDE Plasma, Noveau driver and 3 external displays. Often times, I have display issues (usually with displays connected through my dock station).
Setup
All 3 external monitors are 1080p, supporting up to 144hz (though I usually configure them with 60hz on Fedora).
I’m trying to perform the following setup:
- Built-in display disabled.
- Display connected via HDMI at 1080x1920@60
- Displays connected via DP (dock station, which is connected via USB-C) at 1920x1080@60
Here’s a print of the configuration in KDisplay:
The problem
The problem is, even though the displays show as properly configured, the two displays connected to my dock station do not light up (as if there was no signal).
May I get some help to fix this?
Please let me know if any further details are needed (not sure where to check for logs on this kind of issue).
