I am trying to get vncserver working on CentOS 8. Fully updated.
On the console - logged in as a normal user I run: export DISPLAY=:0.0 xhost + /usr/bin/x0vncserver -display :0 -rfbport 5901 -passwordfile /home/silentm/.vnc/passwd
I get this error: Invalid MIT-MAGIC-COOKIE-1 key/usr/bin/x0vncserver: unable to open display ":0"
Based on the error I changed the DISPLAY=:0 and tried again - but same error.
Am I doing something wrong? I dont really need this to start as a service was just trying to start by hand.
Is there an X11 server running, listening on display :0.0? It sounds like you said you logged in on the console, that sounds like you aren't running X yet, but are at the text console.
If you want to run vncserver, I suggest using the xvnc@.service included in the package:
https://git.centos.org/rpms/tigervnc/blob/c8/f/SOURCES/xvnc.service
There are instructions in the comments.
