Blank screen: Could not sync environment to dbus.

Hi,
This morning when I tried to login to my computer, I got a blank screen with a small window saying “Could not sync environment to dbus”. Only the mouse pointer is visible. I did not notice any unusual behavior before I shutdown my computer last night. I am able to login using icewm. I looked at some linux forums and one post suggested to switch to tty2 and login using the command “dbus-launch xinit startkde – :2 vt2”. I did and it worked. However, I am only able to login using the command “dbus-launch xinit startkde – :2 vt2” in tty2. If I try to login via SDDM, I am getting a blank screen. When I am in tty2 and type in “plasmashell”, “startkde” and “startx”, I get the following:

xinit failed. /usr/bin/Xorg is not setuid, maybe that's the reason?
If so either use a display manager (strongly recommended) or adjust /etc/permissions.local and run "chkstat --system --set" afterwards

Your help is very much appreciated.

You cannot run plasmashell or startkde in text mode. Both need a running X session.
I’d suggest to choose IceWM on the login screen instead, and try to run them in there.

Btw, did you maybe install Anaconda recently?
That’s known to be able to break Plasma (and possibly also other things) because its installer can add things to the user’s .bashrc that override certain system things like Qt5 and python.

Or additional repos?

Ah! I upgraded Anaconda the day before the issue! I followed your reply to the thread https://forums.opensuse.org/showthread.php/528969-Unable-to-log-in-after-installing-anaconda?highlight=anaconda everything is back to normal. Thanks wolfi323 !lol!
