So i got the asus tuf f15 2022 FX507ZM i7 12700H + rtx 3060. It has a mux switch that is only configurable in armory crate. I cannot find any guide as to how enable it on linux. Moreover intel drivers has a bug so i cannot use the screen at 300hz while connected to iGPU. If i set mux switch to dedicated and boot into fedora, it never reaches boot on nvidia drivers. On noveau drivers, it does reaches boot but the rendering is done by iGPU yet.
How can i fix it and run my display at 300hz?
Ok actually you can’t switch graphic card when game is running
if fedora detects your integrated card and nvidia card
then open gnome app launcher and right on app
you should see open with dedicated card or if your default is nvidia open with integrated card

Is your nvidia card detected?
do screenshot of settings<about
Yes it is detected. But the display is connected to intel iGPU
$ inxi -Gxx

So, i can neither change the refresh rate from settings as intel drivers has a bug which doesn’t let me do that nor can i use xrandr.
But if i am able to connect nvidia gpu directly to the display using mux switch that might work…
Are you using x11?
yes i am using x11
this should help you
Yup tried that doesn’t work.
That’s a guide for optimus, not for mux switch you can look here Mux Switch, Nvidia Optimus and Smart Shift | Learn More . I sadly cannot find any guide for it. 
Did you try switching graphic card in your bios/uefi?
There is no option in the bios. It only get changed through the armoury crate software
did you tried in uefi advanced mode
Cause when you start uefi on asus laptop you are in ez mode
ok try this
yeah no options there for mux switch
and yes i did use supergfxctl sadly doesn’t work in accessing mux switch
You can try flashing hiren’s boot cd PE on usb
remember to flash usb with unetbootin
Hi, have you tried this?
maybe, they Upgraded it a bit
from that i saw they checked on checklist mux switch support
and yeah if it works then you can try
cool graphics quick tile for gnome
