X server: connection refused

[2sdude]

I didn't start X in a while on my RPI3b with RPI 7in touch screen ...
And now I get: "unable to connect to X server: connection refused"

Anybody have an idea?

I found in ~/.local/share/xorg/Xorg.0.log :

May 27 10:07:11 [ 28.995] (EE) open /dev/fb0: Permission denied

I tried to put a /etc/X11/Xwrapper.config, but no cigar (same error message)

Can root start X?
Can you try to comment or remove the dtoverlay=vc4-kms-v3d line?

[2sdude]

Hi, thanks for the response! "root" can't start X either: same errors.
Then I commented out "dtoverlay=vc4-kms-v3d", but now my screen remained black after boot.

I removed the "#" and got my screen back.
