Start a xfce4-session for another user ?

[BobSquarePants]

Hi,

Is there a "simple" way to launch
xpra desktop --start=xfce4-session --bind-tcp= ...

for another user, by a regular user ?

┌───Machine─A─┐         ┌───Machine─B─┐
│             │         │             │
│   root      │         │ root        │
│ ┌─userA     │    ┌────┼─userC       │
│ └─userB ◄───┼────┘    │             │
│             │         │             │
└─────────────┘         └─────────────┘
#userA start the command for as userB, and userC connect.

edit: Linux obviously, no sudo

Running a process as another user is not an xpra question.
There are many ways of doing this, but as you will be crossing security boundaries, there are going to be constraints and consequences.
sudo is a common way, so is ssh or even using containers.
I guess you could also use systemd to automatically launch sessions for users, you could even make it socket activated. But again, not an xpra question per-se.

Thanks @totaam 🙏

indeed, generally speaking, running as is a system/OS question.

but we never know, if Xpra had built-in elevation process.

Thanks for your fast reaction.

BTW Xpra is awesome ❤️ !
