KDE Black Screen

Hi there,

I installed Arch Linux yesterday together with the KDE desktop environment.
Set everything up and now after rebooting, the programs I ran are restored so I can write this post on my pc but the background is completely black.
The desktop sometimes appears for some seconds like it does when logging in, but it immediately gets black again.
My datetime is set up correctly, so that wasn't the problem I think. What else can I show you to be able to receive help?

Thank you in advance

Re: KDE Black Screen

Welcome to the boards,

What's the graphics driver? Post in [ code ] [ /code ] tags without the spaces

glxinfo -B #Needs mesa-demos
qdbus org.kde.KWin /KWin org.kde.KWin.supportInformation #Needs qt5-tools
