Hi. I have Silverblue Rawhide with last developement versions of Gnome Shell and Mutter installed. I have tried to enable rt-scheduler (https://gitlab.gnome.org/GNOME/mutter/merge_requests/460) by:
$ gsettings set org.gnome.mutter experimental-features “[‘rt-scheduler’]”
$ setcap CAP_SYS_NICE=+ep /usr/bin/gnome-shell unable to set CAP_SETFCAP effective capability: Operation not permitted
How to do it properly?
I don’t think you can setcap because /usr is read only. You can run rpm-ostree usroverlay if you don’t mind the setcap being lost next boot.
rpm-ostree usroverlay
It is a pity that we can not set it permanently in Silverblue.
Is it enabled by default now (Rawhide)? After upgrade and reboot:
[tpmajer@silverblue ~]$ ps -e -o s,pid,cls,pri | grep pidof gnome-shell S 1284 RR 41 [tpmajer@silverblue ~]$ getcap /usr/bin/gnome-shell /usr/bin/gnome-shell = cap_sys_nice+ep
[tpmajer@silverblue ~]$ ps -e -o s,pid,cls,pri | grep pidof gnome-shell
pidof gnome-shell
S 1284 RR 41 [tpmajer@silverblue ~]$ getcap /usr/bin/gnome-shell /usr/bin/gnome-shell = cap_sys_nice+ep
