I didn't know you could do that. I suppose the solution is X11 only? It
would be nice to have gnome-remote-desktop integration. Though GNOME
seems more interested to support RDP these days (having a glib/gobject
server library would certainly help them to consider Spice, *hint* ;)
Yes, although I'm not sure Wayland support would be hard.
The second is user A getting access to a new session for themselves. I
don't feel blocked on this case; the work should be straight
forward, if
fiddly (I may regret those words; doing a secure 'su' like function out
of apache may be harder than I think).
Multiple user session is tricky. Afaik, this is mostly used for desktop
development. The instructions to setup such environmnent change over
time and desktop. Did I miss something? What's the use case?
The use case is I've got a server I'd like to get access to. I hit a
web page, provide my credentials, and I have a full login session.
Using xdmcp/gdm has the virtue of going through 'standard' channels.
The 3rd case, however, has me troubled. This is the case that user A
(potentially apache) starts x11spice which then does an xdmcp
request to
gdm, and eventually supports a log in by user B. This makes it
challenging to provide a way for user B to launch a spice agent or a
pulseaudio daemon and have it securely connect back to the spice
process
started by user A. The approach I've used in the past is to have a
privileged binary use information from an X atom to adjust socket
permissions. But that feels unsatisfying, and it seems to me that this
is an area with a lot of modern thinking that I've largely missed.
As an added complexity, in the ideal case, you have a vdagent
running as
user A during the login process, which knows to reap itself and give
way
to a vdagent launched by user B.
I was hoping that others would have modern instincts on how to more
correctly implement the third use case. Clue bats or other ideas
welcome.
This is systemd/desktop territories, and I don't know what would be the
best way to do all that. I would suggest you ask the
gnome-remote-desktop & systemd/logind developpers, or other desktop
developpers how they plan or not to solve it.
Check, thanks.
Cheers,
Jeremy
