No longer working correctly after latest SteamOS update

[ibanezbass]

It looks like the gamescope variables are no longer being consumed correctly after the latest steamOS update. Output always remains on internal display.

I was able to fix this by setting a gamescope environment variable with systemctl.

MESA_VK_DEVICE_SELECT={vendor_device}

And then unset it for iGPU mode.

oh, I am having the same issue on bazzite as well. Can you elaborate on how to do this? thank you very much :)

This command will output the GPUs and their IDs
~ sudo lspci -nn | grep -i vga

08:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Navi 21 [Radeon RX 6800/6800 XT / 6900 XT] [1002:73bf] (rev c3)
64:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Phoenix1 [1002:15bf] (rev 04)

Then you set the env like this with the IDs you found. I'll use mine as an example.
~ systemctl --user set-environment MESA_VK_DEVICE_SELECT=1002:73bf

Then, you can click on the switch to TV in the plugin. To go back to iGPU:

~ systemctl --user set-environment MESA_VK_DEVICE_SELECT=
Then click the switch to iGPU

Thank you, this looks pretty good.

But tbh I found this Decky Plugin some days ago https://github.com/TiPSilva/egpu-switch

This one only has 3 buttons and works pretty reliably in tandem with all-ways-egpu.
