If you have not already, I would recommend opening a bug against upstream tigervnc. As I said, I think it needs to re-work it's runtime directory handling, and that is something that is best driven by upstream, as opposed to in Ubuntu.

There are at least two problems with this: 1: On Ubuntu, automatic age-based cleaning of /tmp is enabled by default. This is problematic in general (see bug #2088268), but specifically the /tmp/tigervnc.XXXXXX directory can get removed. If /tmp has the noatime mount option, the removal always happens 30 days after the VNC server is started. Without noatime, the removal happens if there is a 30 day period without any new connections to the VNC server. When the directory is removed, the VNC server becomes inaccessible. 2: If the credential files (e.g. password) in ~/.vnc/ are changed, the running VNC server will not pick this up and will continue to use the old cached credential files. I think there should at least be a mechanism to enable/disable this caching behavior via a configuration file (or a command line argument). Also, if such caching is done, I think the proper location would be under $XDG_RUNTIME_DIR instead of /tmp.
