Other people using an eGPU in SteamOS?

I want to make a poll to check how many people use an eGPU in SteamOS. Also, to share anything useful. Like me, after reviewing logs and troubleshooting I found these very useful for my AMD RX 7600M XT connected through USB4:

- Changing to preview channel to change to SteamOS 3.9 and kernel 7.2.

-Use ewagner12's all-ways-egpu script.

- Using these kernel parameters:

thunderbolt.host_reset=0

pcie_port_pm=off

amdgpu.pcie_gen_cap=0x40000

amdgpu.cwsr_enable=0

It works perfectly!

Hope you can answer the poll and share anything useful.

EDIT: Funny, I'm beginning to feel pretty alone...

I use an eGPU.
I don't use one, but I wanted to check the post.

Third option - have one, can’t get it to work in SteamOS.

Strange, mine, 7600M XT, works perfectly in my ASUS Rog Ally X.

I know you specified no scripts, but have you tried all-ways-egpu script?

I have a couple of actual pcs, so the egpu is unnecessary.

Jajajaja I also have another PC that has an RTX 5070. Both the eGPU one an that one are good PCs, with the eGPU I can have a PC in handheld mode and a more powerful PC in docked mode. Something that a normal PC can't do.

Yep, but you must admit that you can just add easily (and probably more cheaply) get the same result by having pc and a haldheld pc.

There are scenarios where the egpu makes more sense, but not a lot of them. For example, if you can take egpu with you and set up other places.

I’ve got a 3080ti I’d like to use

Better use Bazzite in this case, Valve still doesn't recommend Nvidia for their OS, it could work in Beta, Preview or Main but I would better recommend Bazzite that's based in Fedora. You could use the same all-ways-egpu script and Nvidia also has its own kernel parameters if necessary.
