Gamemode fails to start on Gentoo Linux

[hnhx]

Describe the bug Running gamemoded -t fails with: ERROR: gamemode_query_status failed to return other client connected (expected 1)! Running a game with gamemode either causes a crash or a memory leak.

To Reproduce Run gamemoded -t or start a game with gamemode.

Expected behavior Gamemode shouldn't fail.

System Info (please complete the following information):

• OS and version: Gentoo Linux, kernel: 5.16.0-gentoo
• GameMode Version: 1.6.1 and 9999 (pulled directly from github)

Additional context Full output of gamemoded -t:

Same issue for me.

OS and version: Gentoo Linux, kernel: 5.15.11-gentoo
GameMode Version: 1.6.1

I get the same error on my system. When I add gamemode to Proton, the game starts with a black screen and nothing else.

gamemode version: v1.6.1

Same issue on Artix Linux. Kernel: 5.16.8-xanmod1-1 Gamemode: 1.6.1-1

[Nano-Ocelot]

Same issue on Tumbleweed Gamemode: 1.6.1-25.32 Kernel: 5.16.15-1

I got it to reproduce (kernel 5.15.48-gentoo-dist, gamemode 1.6.1) and will see if I can try to debug the issue.

update: I'm not very skilled with gdb so this might be very slow. update2: on a vm it's surprisingly annoying to have to deal with mouse desync update3: i gave up, complications between gdb and vm mouse desync and everything, and anyway people may have already found the cause (see below)

I get the same thing even after building with elogind and using 1.7

This is probably because systemd is a requirement to bulid gamemode, but building with elogind should fix that so I expect that there are just errors in the build process. There are still some things to try out though so I'll continue experimenting.

"Maybe you have missing a dbus user session, how are you running your wm/DE? with a DM? xinitrc? If with xinitrc, make sure the last line is exec dbus-run-session and the dbus system service is enabled."

I tried it and it still does not work on my system.

FWIW both 1.6.1 and 1.7 have been working fine for me on Gentoo. I use it regularly. My system uses elogind.

[chewi]

I get exactly the same output from env -u DBUS_SESSION_BUS_ADDRESS gamemoded -t, which effectively nobbles the D-Bus environment. In short, either you're not using D-Bus or you're not running in a D-Bus environment. If the DBUS_SESSION_BUS_ADDRESS variable is not present from running via dbus-run-session or similar (most desktops will do this for you) then this is just not going to work. Plenty of other things will be broken too.

@chewi It works fine here in Gentoo: running gamemode-simulate-game successfully triggers the service via dbus. But I don't use elogind but rather systemd with dbus-broker installed and properly configured.

But I can image that the graphical session is not properly launching a session bus but maybe a user bus? I think the latter configuration mode has been deprecated for a while.

# busctl --user list | grep gamemode

On Gentoo, there should be an executable file /etc/X11/xinit/xinitrc.d/80-dbus which launches the dbus session. Depending on how you start your session, it may work more or less well (e.g. graphical login vs. startx from text console).

BTW I can confirm that using dbus-run-session sway instead of sway works fine.
