Anyway, the information on the Internet was uniformly wrong about how to integrate VNC into systemd. Wrong in many interesting ways. I delved into the systemd docs and finally got Xvnc plumbed into it, and then the problem was that VNC didn't have any X clients to run. So I looked up which display manager Mint uses. It's lightdm. (Question for the peanut gallery: does Ubuntu use lightdm? Canonical apparently wrote it, but Ubuntu might have migrated away.) 8/N #LinuxMint #VNC #LightDM

@kbob@chaos.social I believe Ubuntu *used to* use lightdm, but migrated away around Ubuntu 18.04LTS or similar. (I think the Ubuntu default is now a purer Gnome install; no lightdm *running* on my Ubuntu 22.04LTS anyway.) Unfortunately the X11 to Wayland switch and the sysvinit to systemd switch both rendered most online “share graphical desktop” advice for Linux fairly outdated. Both VNC (as you’ve found) and RDP (RDP also suffered from being forced down Kerberos auth on Windows).

I DuckDuckWent around a little for lightdm + vnc info, and I found some internal design documents for lightdm. Right next to the XDMCP -- no, really! Check this out! XDMCP! As Obi-Wan himself said, now that's a name I've not heard in a long time. Probably since about 1995. https://deepwiki.com/canonical/lightdm/4-remote-access#xdmcp-protocol-support But I digress. 9/N #XDMCP #ThisIsRealRetroComputing
