Laptop HDMI extended Monitor no signal

Hello all
I am swaped from Manjaro. I have installed system, updated and my external monitor on slot doesn't have signal. System sees but monitor dont respond. When I try to switch with WinKey + P for only external monitor I got black on both and need to disconnect hdmi to back to my laptop screen.
Below commands results we can start with.

Hi there, welcome to the forum.

Although not necessarily linked to your issue, this means that a reboot is pending.

Nothing change. I tried garuda versions with Gnome, Cinammon. Its weird because manjaro works like a charm after installation. And i really need external monitor for work :slight_smile:

You cannot compare pears with apples.
Same kernel? Same nvidia drivers? Same KDE version?
There is always a chance to fall into a bug upstream.
See for example this recent KDE bug (not necessarily your issue, but I stumbled upon it a few days ago).
One thing you could try would be to switch to e.g. the linux-lts kernel.


Same laptop. I think its not a problem with window manager
