Support for hybrid graphic cards #20
Comments
Hi @mgerhardy, to be specific here, what sort of behavior are you looking for? Controlling optirun etc. may be something outside of the scope of a daemon, unfortunately. It's also worth noting too that with Vulkan these issues start to go away - the game should allow you to choose which GPU is to be used. |
I'm looking for activating the main gpu automatically. To be honest I'm not sure how optirun works - but for e.g. nvidia-prime it is already enough to export an env var ( for example:
and on the other side:
But I'm not sure what exactly is needed for the other solutions out there. |
Such a feature is out of the scope of GameMode and could not be properly implemented. Let's document this and reference the issue. Closes: FeralInteractive#20 Signed-off-by: Kai Krakow <kai@kaishome.de>
I think with the new gamemoderun command this should be implemented. Currently there are 4 possible options to run an app with a secondary GPU: With that in mind, it should also be added an option to set |
This is a cool idea actually, gamemoderun could evolve into a helper script for this kind of stuff! |
In that case, what happens if you run gamemoderun on an app with built-in gamemode support? Because if Hybrid GPU would be implemented in gamemoderun, it would be a very nice replacement to optirun etc for Hybrid GPU user. |
I think this is a fine situation - the only difference is the daemon sees the app request gamemode twice - a safe operation. |
So is someone working on this? I would give it a shot, but I can't find where the gamemoderun code is (probably would with make, but I never used meson). Nevermind I found it. But I think if gamemoderun stays just a shell script this will be a problem, since loading a config isn't that trivial. |
It's here: https://github.com/FeralInteractive/gamemode/blob/master/data/gamemoderun.in It's not on my immediate list, so I'd say go for it |
I already got the bash script working, wasn't that much work, but I would take some advice on how to get the config. I think the best option would be to add a DBUS option to gamemoded to get the config. Any suggestions? |
@mdiluz Do we want to be adding major functionality to |
Yeah, I'd been mulling on it for a while - realising it'd need access to the config to make it useful kind of makes it a little bit more problematic too. Perhaps it's simple enough for someone to write a wrapper scipt to do this for themselves? |
I wouldn't call it a major functionality for most people. If you have a hybrid gpu, you have to use a command before starting a game anyway. |
Bumblebee, nvidia-prime and all the other options that exist
