change FN-key behavior

[Vitamin-X]

Hey, i got a question

is it possible to change FN+F2 (which normaly turns off the display) to change the Advanced Nvidia Optimus Mux state?.... its nearly impossible to get it working on linux and i honnestly just need to switch outputs without everything else it just needs to turn GPI2 from off to on

notebook codename: PC5x_7xHP_HR_HS EC: IT5570

Are you asking about a specific System76 model?

[Vitamin-X]

i got an "Clevo PC70HR" and it seems like it got the same board then the oryp8 (so popably?) but i gues its also usefull for other linux user with Advanced Optimus Notebooks

i am atleast trying to use the GPU in a VM and wanna switch the output to the VM so i dont need to use the nvidia stuff in linux at all

when i look at the internals its exacly the same just mine is a touch bigger so i gues the Oryx Pro 8 is an is an Clevo PC50HR

https://tech-docs.system76.com/models/oryp8/img/components-highlighted.webp vs https://www.notebookcheck.net/fileadmin/_processed_/a/3/csm_w_offen_88fe231bba.jpg

the file src/keyboard/system76/15in_102/keymap/default.c seems to be the layout (just the wrong language) and cant i just change the function of that combination and add some trigger for it somewhere?

otherwise i cant see anything at all which uses that GPIO pin

worth another comment..

tryed to understand the files for a while and i gues i got the functionality for the mux on the F7 key working, but can someone check if i didnt made any mistakes?

Base unit of oryp8 is the PC[57]0HS.

You will fist need to make it compile, which requires you at least:

• Define K_MUX_TOGGLE somewhere
• Add K_MUX_TOGGLE to key_should_repeat() so it returns false
• Add a guard so only boards that define MUX_CTRL_BIOS can use it

But I'm unsure what you're trying to do:

i am atleast trying to use the GPU in a VM and wanna switch the output to the VM so i dont need to use the nvidia stuff in linux at all

Do you want PCI passthrough, so that the host is using the iGPU and the VM is using the dGPU? (Not that I know how to set that up either.)

[Vitamin-X]

yea the VM is already running fine and i can see it on the external display, but i wanna switch the internal display to the dGPU and would love to do it by the push of an button.

PC[57]0HS

the HS just means its a diffrent GPU mine got an 3070 and i gues the HS was the 3060 there is also an HP with an 3080

• Define K_MUX_TOGGLE somewhere

ah yea i forget about that, now i just renamed the old key to the new "name"

• Add K_MUX_TOGGLE to key_should_repeat() so it returns false

and thats so you dont need to release Fn to push it again right?

• Add a guard so only boards that define MUX_CTRL_BIOS can use it

how can i do that? and is it realy needed?

[Vitamin-X]

ah our german keyboard seems to get one key more right next to the left shift with "<>|" and no clue which pins they use in the matrix, i hope thats not messing all up

but so far no errors, now i need to be brave enouth to test it i gues

[Vitamin-X]

i think i got all mistakes fixed now.. and made it optional with "CONFIG_MUX_COMBO=y" so its still compatible to the other models, it also seems like that FN+F7 is just a replacement for super+P soo you might like to merge that key combination to your code too cuz the default option is not realy an shortcut and switching the mux is soooooo much more usefull

the picture on the key also pretty much matches that behavior
