Dear Maintainer,

gamemoded -t fails with a message of "ERROR: Governor was not set to
performance (was actually powersave)!".

This is after installing using the meta package of "gamemode". From journalctl
it appears the package is missing some polkit rules:

Hello,

This is permission issue. You must be in group `gamemode`.
This group is used in `/usr/share/polkit-1/rules.d/gamemode.rules`
provided by `gamemode-daemon` package.

The bug is that the package installer does not create this group.

After manual create `gamemode` group and add yourself to this group
tests are passed.

Regards,
Robert Paciorek

Greetings,

	I installed `gamemode` and ran `gamemode -t`. Everything verified except the CPU governor setting.
     ineffective)?

	I manually added the group `gamemode` to my system, then I added myself (the user) to that group.
	```
	sudo groupadd gamemode
	sudo usermod -aG gamemode $USER
	```
	This solved the problem.
