Option to disable modesetting

[StephanX]

Hi!

On my setup, everything works great, except I need all of Section "Module" removed for the xorg config file (for the egpu) to work. I'd love some sort of flag like '--nomodesetting' so that only the Device group is generated.

When modesetting is activated, gdm does not land on any connected monitor.

egpu-switcher version 0.18.1 on Arch (up to date) via Arch/Aur (gnome if that helps)
i7-6700HQ Alienware r13 + igpu gtx1060 + evga gtx 1070 / Akitio Node

Hi,

for me it is the same. I am on Pop OS 22.04 with nvidia-driver-525 , kernel 6.1.11-76060111-generic and egpu-switcher version 0.18.1 and my external gpu is only working when I comment Load "modesetting" out in xorg.conf.
Which i have to do every time after I am using my laptop without the egpu. Otherwise it is just stuck in boot and will not launch x11 only commandline.

Thank you very much!
egpu-switcher is still a great help!

@timpauli Good to know, thanks for the report. I'll prioritize this issue higher then.

Could you reproduce the issue again and upload the logs for the failed X.Org session? Just so I get some background information on what exactly is happening there.

cat /var/log/Xorg.0.log

---

A potential workaround might be to enable early KMS start?

/var/lib/gdm3/.local/share/xorg/Xorg.0.log

Xorg.0.log

Did not try the early KMS start yet.

Thank you

I implemented this in 0.19.0. The switch command now has the --nomodesetting flag. Or for an even easier way, update your config so that the modesetting module is always omitted.

/etc/egpu-switcher/config.yaml

egpu:
    nomodesetting: true # add this line
    driver: amdgpu
    id: 1153611719250962689

Hi.
It didn't work for me.
Would you have additional suggestions, please?
I have an egpu build that will only work on linux (having BSOD in windows) so I'm relying on this.

*the reason I believe it'll work in linux is because I'm getting video/display while connected the hdmi cable in the egpu but I'm pretty sure it is rendering with the igpu (not even the degpu/nvidia) because I can "feel" the slowness while typing, browsing etc. Plus, the "glxinfo -B | grep -i render" command returns the igpu name.

Thank you
Regards
