I am trying to open a VNC to display :0 in Fedora 25 but I got this error.

[myname@myserver ~]$ x0vncserver -display :0 --geometry=1400x900+0+0 -PasswordFile=/home/myname/.vnc/passwd No protocol specified x0vncserver: unable to open display ":0"

I have searched internet for a solution but I always end up in old information which seems not to be accurate anymore.. Has someone found the same issue? How to solve this ?

Thanks, Slid4r303

That sounds like a problem of TigerVNC not being able to run under Wayland.

Please try again in an and report back (On login screen, after clicking your username, click the little gear, and select Xorg session, then login).

If that works, and you want to make X.Org your default display server, check out this post

Hello Florian,

Thank you for your answer.

Trying to logging in with xorg was ok but still when start x0vncserver the same result is found. Also tried the WA but still no good.

I am able to start (tiger)vncserver either via systemctl or at user shell - this works good following the Fedora 25 Admin Guide. But what I am trying to accomplish is to remote desktop the DISPLAY=:0
