Failed to start remote desktop service VNC? Reasons are here!

VNC is a graphical desktop-sharing system in order to control another computer remotely. But there are different reasons for VNC service start to fail. Our Support Engineers handled many cases and we found that the two of the main reasons are:

• VNC password not set
• VNC fails to clear the files

Today we are going to discuss how our Support Engineers fix it for our customers.

1. Failed to start VNC occur when password not set

There are situations where customers approach us saying failed to start remote desktop service vnc.  Our Engineers handled such issues recently. When checked we found that the VNC password was not set. So, we set the password for the user- Mynewuser defined in the configuration file and restarted the service. This fixed the issue.

2. VNC failed to clear the files

Recently one of our customers approached us saying that he is getting an error when he starts the VNC service. He also mentioned that he is using TigerVNC.

So our Support Engineers tried starting VNC and we got an error when trying to start VNC service.

Job for vncserver@:X.service failed because a configured resource limit was exceeded. See systemctl status vncserver@:X.service and journalctl -xe for details.

So, we checked in detail and found that tigerVNC failed to clear the files created under /tmp and /tmp/.X11-unix/. So we removed them manually using the command below:

rm -f /tmp/.X11-unix/Y ; where Y is the file to remove.

Then restarted the server using the command:

systemctl start vncserver@:X.service

Note: Fix may vary depending on the OS and VNC (TightVNCTigerVNC, UltraVNC, etc).
