I've just installed Mir and I'm wondering if I'm actually running it or if it fell back to X. How can I tell if Mir is running?
You can also simply check if the system compositor process is running:
ps afx | grep unity-system-compositor
On my system running Mir it returns something like this:
jorge@jillociraptor:~$ ps afx | grep unity-system-compositor
4260 pts/0 S+ 0:00 | | _ grep --color=auto unity-system-compositor
1606 ? S 0:00 /usr/sbin/unity-system-compositor --from-dm-fd 9 --to-dm-fd 13 --vt 7
Machines NOT running Mir will not show unity-system-compositor running.
