New subject: tigervnc fails with "Cannot establish any listening sockets - Make sure an X server isn't already running(EE)"

Friday, 13 January 2023

Hi,
I have a fedora37 desktop install with tigervnc-server and can't get it to
start. I'd like it to start on system boot.

I've followed the HOWTO.md as well as numerous examples online, and can't
figure out what's wrong.  I've set the vncpasswd for the user listed in
vncserver.users.

/etc/tigervnc/vncserver.users:
:1=gary

$ cat ~/.vnc/config|grep -Ev '^$|^#'
session=gnome
securitytypes=vncauth,tlsvnc
geometry=800x600

# systemctl start vncserver@:1
Job for vncserver@:1.service failed because the control process exited with
error code.
See "systemctl status vncserver@:1.service" and "journalctl -xeu
vncserver@:1.service"
for details.

Could missing fonts really cause this? What more can I do to troubleshoot
this?
