[Bug]: Steam not appearing on Intel Arc A770m

[Toiartu]

Describe the Bug

I am running Fedora Linux 43 Server on an Intel NUC Serpent Canyon and I am encountering the following issues:

1. Steam doesnt show up or have a GUI
2. Any window on top of the invisible Steam is glitchy
3. Starting Steam from terminal also causes the same issue.

Steps to Reproduce

1. Run this container on an Intel Arc A series
2. Try to open Steam

Expected Behavior

Steam would've opened and I could've logged in.

i have a similar issue running intel arc B570
but I'm running it through TrueNas, i assumed at least for my case its because the gpu is detected but not actually being utilized within the vm. other applications are utilizing it just fine.

ls /dev/dri card0 renderD128
but
glxinfo | grep "OpenGL renderer"
returns llvmpipe

[CliffHan]

Same problem here.
When I attached docker with root, steam could run.
So I think maybe switch to root user could solve this, not tested yet.

[mpgrashoff]

after some searching it seems that:
Kernel / driver | ✅ OK
Mesa | ✅ OK
Permissions | ❕ MAYBE
(might need to add lightdm or render group perms to your user)
X server | ❌ Software-only

Xorg seems to be running but without gpu-acceleration causing
the mesa drivers to fall back to llvmpipe (cpu software render)

i'm going to try and fix this now if i manage ill upload a step by step for troubleshooting and fixing

Adding the user “default” to the render group and modifying the Xorg config file (/etc/X11/xorg.conf) in place to the following solved my issue. Though the ui becomes even more sluggish if without connecting to any HDMI device, which iirc is a known issue to intel’s GPUs.
