Hi,

Connected second monitor to laptop returns black screen but is detected on KDE using integrated AMD Radeon graphics. Tried various displays configurations, presentation mode.

What else I can do trying to fix it?

Please show output from inxi -GSaz (using code tags).

Putting ~~~ alone on each of two lines, then pasting that input/output in between those two lines does the same thing. Either will preserve the output formatting. :slight_smile:

There is no second monitor, because it’s now set to external screen in KDE display configuration and if connect see nice black screen :slight_smile: looking how to change it without UI.

p.s connect with HDMI, with usb-c doesn’t work at all.

I turned off my monitor and on again and openSUSE got it, looks fine now! Thanks again :slight_smile:
