Warning: remote_server:17 is taken because of /tmp/.X17-lock Remove this file if there is no X server remote_server:17 ...

The "remote_server" is a remote server that is used by many users at the same time. Now, when I run "vncserver -localhost no -geometry 3840x2160" command to try to start my own VNC server session with a system-assigned display ID (hopefully), I got the following error:

Files /tmp/.X17-lock and /tmp/.X18-lock are files created by other user which I don't have permission to delete. The display :17 and :18 may be legally being used by the user, or the VNC server was crashed for this user, I don't know. I don't have the intention to take display :17 and :18; it's ok to let it be. There are still tons of display IDs available for me to use in the system. So my question is: how to have the vncserver bypass the display IDs being occupied, automatically assigns one to me that is available (I don't mind what number it is), and start the VNC server without errors so that I can proceed with my work in the GUI gnome desktop? I have searched Internet but didn't find any solution that is applicable to me.

It looks like you are hitting this bug:

https://github.com/TigerVNC/tigervnc/commit/38c6848b30cb1908171f2b4628e345fbf6727b39

An upgrade to TigerVNC 1.12.0 or newer should hopefully resolve it.
