Public bug reported:
On Linux Mint Cinnamon, gamemoded -t failed the CPU governor test even
though the system supports the performance governor.
The CPU governor could be changed manually with sudo:
sudo /usr/libexec/cpugovctl set performance
But gamemoded -t failed with:
ERROR: Governor was not set to performance (was actually schedutil)
journalctl --user -u gamemoded showed pkexec authorization failures for:
/usr/libexec/cpugovctl set performance
/usr/libexec/procsysctl split_lock_mitigate
Both were denied with:
Error executing command as another user: Not authorized
The installed files are from gamemode-daemon:
gamemode-daemon: /usr/bin/gamemoded
gamemode-daemon: /usr/libexec/cpugovctl
Adding a local Polkit rule allowing my user to run
/usr/libexec/cpugovctl and /usr/libexec/procsysctl through pkexec fixed
the issue. After adding the rule, gamemoded -t passed all tests,
including the CPU governor test.
This appears to be missing or incomplete Polkit integration for the
gamemode package/helper tools.
