Multi-GPU

[Vakkaria]

Are there any package to handle multi-GPU? Because i have intel+nvidia and it already knows how to use both together

[kRHYME7]

see Hyprland wiki

It's using both GPUs by default... It's interesting, because if i will only use nvidia, hyprland will be broken for my case. So i don't know why...

It helps, thanks a lot

What did you do to fix it because on the wiki page they say that you need to do all sort of stuff like installing nvidia drivers and so on but I thought that was already done in hyprdots?

[Vakkaria]

Alright, one more question. Can i use supergfxctl and asusctl for change mode to MUX Switch?

[kRHYME7]

Are you using an Asus laptop? If it's ROG I guess you should. we got a patch for this too. Hyde inject asus_patch to prepare your repo and have the services running. This is pretty much essential as some of their drivers are proprietary.

But please check your device first. Search Asus on archlinux you'll see some posts about that

I use asus tuf gaming, I saw somewhere that arch (or hyprland) doesn't recommend to use optimus manager.

Should help

[Vakkaria]

I've been there. I'm just not sure if it will work properly on hyprland, because there have been things that don't work on hyprland but on arch. Anyway, thanks for help!
