Internal laptop display not recognized

[JEdwardsD]

After setting up egpu-switcher my computer would stop recognizing the internal display and only output to the external display. Everything worked after the initial install but the internal display no longer functioned after closing and opening my laptop lid to wake it from sleep. The screen works whenever it's disconnected from the egpu. A secondary external display connected to the laptop and not the gpu works fine, too. Restarting my pc would sometimes fix the issue on Ubuntu, but I recently switched to Manjaro and after the problem arose it hasn't gone away. Reinstalling and rerunning the script didn't fix anything in Manjaro.

Can you try editing your xorg.conf.egpu to remove the Section "Module" block and add something like this:

Section "Device"
    Identifier  "igpu"
    Driver      "intel"
    BusID       "0:2:0"
EndSection

be sure that the bus ID matches your iGPU as given by lspci (and be sure convert the hex number from lspci to decimal)

@JEdwardsD Did you try out the suggestion from @ewagner12?

I ended up reflashing my OS due to issue https://github.com/hertg/egpu-switcher/issues/43. Haven't run into the problem again, but if I do I'll let you know if this solution works. Thanks!

I've been having this same issue, and have not been able to find a solution. I've tried the solution proposed by @ewagner12 but that just led to only my igpu working on the Internal display.

I've run into this issue on two Distros so far Zorin OS and Ubuntu Budgie 20.04 On Zorin, the first time I loaded up egpu-switcher both screens worked but the moment I disconnected the eGPU they never both worked again. On Ubuntu Budgie, I was never able to get both screens running at once.

I am also having this issue. I tried the config from @ewagner12 but no dice. I am only able to have my external display work when I have my eGPU connected.

I also tried from other configs I found on the web, but none seem to work (some make it so neither display works).

I have also observed another strange behavior when I select an older kernal version (5.11.12-300). It'll be unable to find the Nvidia Kernal Module and falls back to noueva. When this occurs, both of my monitors (internal and external) work. And the Windowing System is Wayland.
