Goes to login screen but cannot complete re-login

[Lennox84]

Thank you soo much for creating this script, hopefully, we can solve this together.

System: Linux fedora 5.13.6-200.fc34.x86_64 #1 SMP Wed Jul 28 15:31:21 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux eGPU: AMD 5700xt Mantiz Saturn Pro II Fedora KDE spin Lenovo C940 Compositor: OpenGL 3.1 Scale method: Smooth

Installed and set up trying to only disable iGPU and AMD HDMI audio, disable only iGPU, disable all iGPU, AMD 5700XT & AMD HMDI audio.

The screen goes to the login screen on the laptop monitor only. entered password and then loads KDE logo (Theme Breeze Dark) on both screens with loading circle swirling Logo disappears, and the swirling circle continues. Mouse movements on both screens are lagless, but the screen remains blank. Cannot CTL-ALT-DEL. The power button does not respond Cannot go into TTY Need to press and hold PWR to turn off. Upon reboot quite a few kernel issues come up, I restart immediately and then reboots with no issues and no kernel issues. System is back to normal

Let me know what else I can test or run to give you more data to go from. Looking forward to your response

Ok thanks for testing. First can you try setting up to disable the iGPU but nothing else (n to all other prompts). Also can you send the output of these two commands:

cat /usr/share/all-ways-egpu/usr-bus-ids
lspci -k

Actually hang on, I installed fedora KDE to test it out and it looks like I overlooked some things that SDDM does, so I'll issue a patch and then you can try it out

[Lennox84]

Hey mate!

So just to confirm I had already tried disabling iGPU only, described in the 1st post.

The below was done after running setup and making sure only iGPU is disabled, but your command cat /usr/share/all-ways-egpu/usr-bus-ids comes up with nothing because the file that exists is cat /usr/share/all-ways-egpu/user-bus-ids --- OUTPUT: [bruno@fedora ~]$ cat /usr/share/all-ways-egpu/user-bus-ids 00:02.0 i915

I hope this helps.

[bruno@fedora ~]$ cat /usr/share/all-ways-egpu/usr-bus-ids cat: /usr/share/all-ways-egpu/usr-bus-ids: No such file or directory

Yeah that configuration all looks good. When you get a chance, try out installing LightDM or GDM3 instead of SDDM. It looks to me like SDDM + Plasma Wayland currently has an issue with restarting the display-manager, which has to be done when switching like this. Hopefully when SDDM moves to wayland that will be fixed, but for now I'd use LightDM and see if the issue goes away or changes.

[Lennox84]

Legend! Thanks, will try it in the next hour or so and let you know. 💪

[Lennox84]

OK so I'm not sure if it's working or not.

Tried to use lightDM but everytime I rebooted it wouldn't load the login screen so I had to drop down to TTY and reverse it. I then installed GDM... unfortunately it installed complete gnome lol (I'll fix that later) But I did load into GDM and was successful in running the script and booting back into my system which looks like it's running off the eGPU but I don't know how to tell if it's the primary display being used? Any commands I could run. The Laptop fans are definitely running lower which leads me to believe the script is working because the load is elswhere

Performance tho... It a little better than running extended mode and mirrored but not by much, there's still decent lag on the screen from typing and mouse use. (Don't get me wrong I'm not complaining but I'm happy to continue to experiment and guinea pig any idea we have of improving performance if possible.)

Let me know what I can do.
