I have looked at a few posts, but have not found any of them to be helpful. I have a laptop with two video cards. And I also have one monitor that is connected via HDMI. However, in the display settings it shows. Physically, however, the monitor does nothing. Even if I turn on duplication of screens for example. So the monitor is black.
I have a second laptop where I also have Manjaro, where both screens work normally. And I also have a second drive on my current computer (the one where the screen doesn’t work) where I have Windows 10, where the screen also works normally. At the very beginning (after installation), it didn’t show me the monitor even in the display settings. But then I messed around with the drivers and installed 1.15 Kernel, Majnaro headers and cuda. And then the monitor started showing up in the settings, but it still didn’t work.
