[SOLVED] DISPLAY errors

Hi there,

I've got the usual env var of DISPLAY=:0.0

Trying to run a program like xclock for example, as root - no joy. Then I discover it won't run even as myself.

I get these errors:

Code:: krieger:[/home/kevin] xclock Invalid MIT-MAGIC-COOKIE-1 keyError: Can't open display: :0.0 export DISPLAY=krieger:0 krieger:[/home/kevin] xclock Error: Can't open display: krieger:0

I was trying to run "luckybackup" from the command-line:

Code:: krieger:[/home/kevin] luckybackup Invalid MIT-MAGIC-COOKIE-1 keyqt.qpa.screen: QXcbConnection: Could not connect to display :0.0 Could not connect to any X display.

What am I doing wrong? Is Zorin not using X DISPLAY?

Hmm, this is my second attempt to post a follow up, not sure what I did or didn't do.

So I thought, that is never going to work, I've only used DISPLAY=:0.0 during my decades
of *nix usage.

Anyway, it worked just great! The who told me I was using :1, so I set the DISPLAY=:1
and xclock and luckybackup both worked. Su'ing to root and I could still run luckybackup
but now all the permissions/ownership was correct!

Thanks a bunch :!:

(I'd mark this RESOLVED, but I dunno how.)

So, my efforts to destroy your machine failed?
Rats.

To mark as resolved, hit "edit" on your first post and edit the title to display "Solved."
