Gamemode won't start with egpu

I am using aoostar xg76xt (7600xt) egpu with Rog Ally X. I did all-ways-egpu set up (method 2 and 3). Installed LACT, but gamemode does not reliably boot with egpu (thou it miraculously did few times).

status output from all-ways-egpu: https://pastebin.com/kkDdXLZz

I also did

rpm-ostree kargs --append=thunderbolt.host_reset=0

rpm-ostree kargs --append=thunderbolt.host_reset=0

without it, the device doesnt boot egpu after restart (egpu work indicator lights up for a moment during restart and then it stops), until I replug it, with it, it boots, but gamemode crashes, and desktop with steam login window opens.

It might be worthwhile to reinstall the script

all-ways-egpu uninstall

Okay trying now

CheckYourFax•4/15/25, 11:12 PM

the maintainer often improves the install script so it might work better after reinstalling

IgorьOP•4/15/25, 11:18 PM

I did install it yesterday though..

CheckYourFax•4/15/25, 11:19 PM

I'm not a huge expert on gamescope, but just all-ways-egpu i think isn't enough to make game mode work OOTB

CheckYourFax•4/15/25, 11:20 PM

i think you have to specifically force a PCI rescan when game mode starts

CheckYourFax•4/15/25, 11:20 PM

its OCuLink right?

IgorьOP•4/15/25, 11:21 PM

Its usb4

CheckYourFax•4/15/25, 11:23 PM

Have you tried methods 2 or 3 of all-ways-egpu?

CheckYourFax•4/15/25, 11:24 PM

you need to select it during install

CheckYourFax•4/15/25, 11:24 PM

methods 2 and 3

Radeon 7700 XT eGPU won't boot into gaming mode (ROG Ally X)

CheckYourFax•4/15/25, 11:27 PM

Here's a lot of information that might help

IgorьOP•4/15/25, 11:28 PM

Yes, but I am not sure what should I choose specifically, when configuring them. I did guided setup and answered yes to method 2 and 3. But if I then select them from menu, I am not sure which option is right

Method 2 options are:

Set boot-vga Flag to eGPU
Set boot-vga Flag to default
Force boot-vga to iGPU
Configure boot-vga Flag at boot

Method 3 options are:

Set compositor variables to eGPU
Set compositor variables to default
Set compositor variables to internal
Configure setting compositor variables at boot

IgorьOP•4/15/25, 11:28 PM

I tried 1 for both

Few times it miraculously booted gamemode with egpu it displayed both in mangohud. Also I am using internal screen

CheckYourFax•4/16/25, 1:01 AM

I think someone else has to take a look at this. @Valerie Do you have any idea? Sorry for tagging you but you're our eGPU heroine

mindxpert•4/17/25, 6:34 PM

@Игорян did you do the guided setup? That's what I did on mine. Select the eGPU when asked, and then the iGPU. After that you have to add y to method 2 and 3.

mindxpert•4/17/25, 6:34 PM

Also can you post what your Status shows on all-ways-egpu?

IgorьOP•4/17/25, 7:01 PM

Yes I did, do I need to manually set up method 2 and 3 additionally, or guided setup should be enough? I posted status output in the original message

IgorьOP•4/17/25, 7:02 PM

By manually setting up I mean these options

Gamemode won't start with egpu

mindxpert•4/18/25, 10:01 AM

Oh I missed the links to your status, and that seems to show as expected from what I can tell.

Your guided setup looks fine and you usually don't have to use the Method 2 and 3 options with the all-ways-egpu once you've done the guided setup.

mindxpert•4/18/25, 10:03 AM

Can you try manually with setting Method 2 to option 1.
Set boot-vga Flag (Method 2) -> Set boot-vga Flag to eGPU

Then restart the display manager.

mindxpert•4/18/25, 10:04 AM

Before I was able to get boot to work this was how I was able to get gamemode to external monitor. Your Rog Ally screen should be "off" like not literally off but will show a tty like screen.

IgorьOP•4/18/25, 8:09 PM

I tried reinstalling all-ways-egpu and doing only guided set up + restarting display manager. It rebooted and then crashed my gamemode

IgorьOP•4/18/25, 9:35 PM

after reboot, it booted gamemode first time, but if I restart the ally it crashes the session

IgorьOP•4/18/25, 9:38 PM

Status says it cant detect egpu

IgorьOP•4/18/25, 9:42 PM

If I launch lact in desktop mode and reboot it boots to gamemode with egpu detected, maybe thunderbolt initialisation error? I deleted

rpm-ostree kargs --append=thunderbolt.host_reset=0

rpm-ostree kargs --append=thunderbolt.host_reset=0

, maybe I should reenable it, not sure what it does

IgorьOP•4/18/25, 10:14 PM

I did

thunderbolt.host_reset=0

thunderbolt.host_reset=0

, but the gamemode still crashes on reboot

IgorьOP•4/18/25, 10:27 PM

I also did

rpm-ostree kargs --append=amdgpu.runpm=0

rpm-ostree kargs --append=amdgpu.runpm=0

per @ mindxpert`s comment, session still crashes

mindxpert•4/19/25, 4:55 PM

I’m sorry can’t be of much help. I’d suggest opening an issue on all-ways-egpu github as I’ve noticed the dev is very helpful.

IgorьOP•4/26/25, 12:07 PM

@Valerie sorry for tag, maybe you could please take a look?

Zetarancio•4/26/25, 12:55 PM

Report with PCI=nommconf please

ZZetarancio Report with PCI=nommconf please

IgorьOP•4/26/25, 3:49 PM

I tried, same result, game mode crashes

Zetarancio•4/27/25, 3:16 AM

Did you force (and check that they are applied) the limits for your card into lact?

I wanted to confirm that this worked for me. Allows me to boot with my AMD egpu plugged in over TB right into game mode on the internal display.

Sorry for the ping, could any of you help me with this egpu set up ally x + rz6800 over tb. I ran the new script and im getting output straight away but games take forever to launch and the performance bar is showing my usage on the igpu not the egpu.
