https://gitweb.gentoo.org/repo/gentoo.git/commit/kde-plasma/powerdevil?id=82403b226a4ed27dfe7c0838ec35b5929ec2504e broke powerdevil by default on musl-based systems. Reproducible: Always Steps to Reproduce: Install powerdevil on a musl system without forcing USE=-filecaps Actual Results: powerdevil doesn't work: * Screens don't go to sleep * KDE System Settings -> Power Management displays "Power Management settings could not be loaded. The Power Management Service appears not to be running." Expected Results: Power management works. Same basic issue as https://bugs.gentoo.org/946505, but for powerdevil instead of kwin. From https://bugs.kde.org/show_bug.cgi?id=417227#c13: > [15:45] <fvogt> Just remove CAP_SYS_NICE and it'll work > [15:45] <PureTryOut[m]> And how would I do that? > [15:47] <fvogt> setcap /usr/bin/kwin_wayland cap_sys_nice= > [15:48] <fvogt> Actually, just setcap -r /usr/bin/kwin_wayland > [15:49] <PureTryOut[m]> You're right, that fixed it! :tadad > > [15:54] <fvogt> kwin_wayland's CAP_SYS_NICE makes _dbus_check_setuid trigger and so it ignores environment variables > [15:57] <fvogt> It works on glibc because it only checks the suid/euid > [15:57] <fvogt> On musl, issetugid is available and that doesn't like capabilities The same applies to powerdevil, and the end result is that it can't communicate over dbus. The fix for #946505 was to mask the filecaps USE flag for kwin in the musl profile. Should do the same for powerdevil.
asturm did warn me :)
