Hi all,
This post is a duplicate of my ask Ubuntu question.
I started thinking that the question might need too much interaction for ask Ubuntu. That's why I'm posting it here.
I also didn't really know in which section to put it.
Please tell me if I can do anything better.
I have a three monitor setup like this.
Everything works fine like this. But whenever I set the Built-in Screen to a lower resolution, the Built-in Screen just goes blank. The other two screens keep working fine. When I set it back to 1920x1080 it comes back up. The screen space seems to be rendered, since I can move my mouse into it, and put windows in it. I can also take a screenshot of it.
But nothing shows up on the laptop screen. The backlight is on and can still be adjusted. System Settings just acts like everything is fine.
I did some searching and also tried ChatGPT, but the problem is so specific that I don’t really know what to look for.
I’m on Kubuntu 23.10. The laptop is an HP Elitebook 845 G8, with an AMD Ryzen 7 PRO 5850U with Radeon Graphics.
