Is there any good solution to remote into Qubes Dom0 Gui?
[I know that this is not inline with the purpose of Qubes, but I have a use case wherein I really need to be able to remote into Dom0 and would secure that connection as much as possible.]
Optional qubes-remote-support package now available from repositories (strictly opt-in, no package installed by default; no new ports or network connections open by default; requires explicit connection initiation by the user, then requires sharing a code word with the remote party before a connection can be established; see #6364 for more information)
Those improvements would highly reduce trust implied from remote support third parties, where that “wifi slider” could be turned off by support requester at any moment, and where dom0 screenshots from the support requester would permit some kind of traceability of what happened along the support session, alongside of logs.
But those were not considered under Nlnet grant accomplished work, and leaves place for further improvements.
