It would be great if I could enable X11 isolation in my profile instead of having to pass it as an argument through the command line.

My first attempt to implement it failed miserably.

I need to detect x11 long before loading the profile from the file. Today it works this way: detect x11, start xpra or xephyr, restart firejail this time without --x11, load profile, start sandbox.

Edit: tried again, it just worked!

$ man firejail-profile
[...]
       x11    Enable X11 sandboxing.
