KDE Stuck on Black Screen With Cursor After Login

Hi!
I recently installed Arch Linux.
For my desktop environment, I installed 'plasma-meta'. And display manager is 'sddm'.

The problem is, after logging in KDE is just stuck on a black screen and a cursor. I can move the cursor though.

I have also installed xfce4 which works just fine. The problem only occurs with KDE.

What I have tried so far?
Remove .config, .local and .cache directory.
Uninstalled and reinstalled Xorg, sddm, plasma.
Created new user and logged in with that.

Still same issue persists.

Posted images of the screen here.

Re: KDE Stuck on Black Screen With Cursor After Login

Compare your xorgs logs for a plasma and xfce session.

Arch + dwm   •   Mercurial repos  •   Surfraw

Re: KDE Stuck on Black Screen With Cursor After Login

I have the same problem .. xfce4 worked well with lightdm, but when i removed xfce4 and installed plasma and sddm instead of lightdm .. i get a login screen but as shown in the screenshots you added, I get a black empty screen , it can run terminal and any other application than can be run from terminal , but no desktop, no nothing.

Don't run it as root, run it as a regular user

Re: KDE Stuck on Black Screen With Cursor After Login

It worked. I just set the timezone and everything is working just fine. Thanks a lot. but it's actually weird that if timezone is not set, all the DE crashes.
