Mine isn't either in that I have allowed myself to run things at higher priority when I tried to get better FPS rates for a game I was playing. I wonder if you're seeing the same with firefox when you allow higher priority, too. Otherwise I don't see how firefox or any other user process should be able to do it (without rtkit). Still it seems unusual that firefox does something it usually can't do. Who would go to the lengths of implementing a feature that nobody uses. The messages in the journal are actually weird: rtkit-daemon[132284]: Successfully made thread 145442 of process 145185 (/usr/lib64/firefox/firefox) owned by '1000' RT at priority 10. rtkit-daemon[132284]: Successfully made thread 2534 of process 2507 (/usr/bin/gnome-shell) owned by '1000' RT at priority 20. rtkit-daemon[132284]: Successfully made thread 2534 of process 2507 (/usr/bin/gnome-shell) owned by '1000' high priority at nice level 0. rtkit-daemon[132284]: Successfully made thread 2534 of process 2507 (/usr/bin/gnome-shell) owned by '1000' RT at priority 20. rtkit-daemon[132284]: Successfully made thread 2534 of process 2507 (/usr/bin/gnome-shell) owned by '1000' high priority at nice level 0. It says 'made owned by'. Does user 1000 not own the process to begin with? Which user owned it before? Or what is that supposed to mean? Eventually it will run into a limit: rtkit-daemon[1121]: Failed to look up client: Device or resource busy rtkit-daemon[1121]: Warning: Reached maximum concurrent process limit for user '1000', denying request. J Will firefox will make its processes higher priority despite the limit is reached since it does it without rtkit?
