Duplicated screens after changing something in audio?

I just installed Garuda Linux today (a few hours ago) and the audio didn’t work. I searched for solutions online and some people talked about changing to pulseaudio and using pavucontrol to manage audio. Instead of the default pipewire.

So I installed pulseaudio, maybe I did something wrong (though I didn’t modify any config file). Anyways, now my two monitors have the same image and I have a phantom “None-1-1” monitor on lxrandr.

I’ve been searching for solutions on this issue for a few hours now, but I cannot find anything similar to it.

Thanks for helping!

I would recommend first to restore your system to older state through snapshot and see if your monitor is back to normal, next please don’t use pulse audio, keep pipewire , I not much frequent in forum for issue related topics but I frequently see people struggling due to pulse audio,

One of the thing I would have tried is to install ALSA support through garuda assistance and see if it does anything or not .

And welcome to garuda community forum:wink: :smiley:
