Laptop Display not Detected

jared · December 4, 2019, 1:53am

I was using two external monitors and the laptop display for a total of three monitors until a kernel and Nvidia driver update caused a series of issues. Currently only external monitors are detected and work fine, the laptop display doesn’t.

Distribution & Version
Fedora 31 and Gnome 3.34.1 on System76 Oryx Pro 5 (Nvidia GeForce RTX 2060 - Nvidia Driver 440.36)
Kernel information
Linux oryx 5.3.13-300.fc31.x86_64 #1 SMP x86_64 x86_64 x86_64 GNU/Linux
When did the issue start happening?
Did anything change that caused it? (hardware change, upgrade)
What steps do you take that cause the problem?
After a kernel and Nvidia Driver update on Fedora 30, the system was booting to Intel Driver only.
I updated to Fedora 31, no change.
After another kernel update, the system would not boot into graphical user mode, I received the error “NVIDIA kernel module missing, falling back to nouveau” but system was stuck there, all I could do was ctrl+alt+del to reboot. I booted into runlevel 3 and updated the kernel again and I was able to boot into graphical mode again now. But the laptop’s display is not working. During boot the laptop display works, I enter luks password, see grub menu, see Fedora logo and spinning wheel, but once it is time for the OS login, the screen goes black with a cursor in the top left corner. If I connect an external display the login prompt is there waiting to login.
output from xrandr with my two external monitors connected:

Personally, I’d just contact System76 support. I’d help, but I can’t replicate your setup so that would be your best bet. Let us know what the solution is, in case anyone else runs into this issue.

I am not an expert with graphics but I would try to login with an external monitor and when you are at the login screen I would select the Gnome session using Xorg rather than the default Wayland and then try it with the laptop display. You can find that option in the cog wheel from the login screen under the user name.

They only support PopOS and Ubuntu unfortunately.

jared · December 10, 2019, 2:34am

The options I have are Gnome and Gnome Classic, I tried both but had the same result with each.

david.smyth · December 10, 2019, 12:39pm

Also not a graphics expert but interested if you get laptop display if you start the system from a PopOS live USB, maybe worth comparing kernel modules loaded etc between working and not working.

vinylninja · December 10, 2019, 12:42pm

Could be that on Fedora the X session is no longer available. But in your case it seems it would not make any real difference. I think the problem here is more serious.

jared · December 12, 2019, 2:40am

The screen is detected on a Pop live usb as well as a Fedora 31 live usb.
How would I go about comparing the kernel modules?

david.smyth · December 16, 2019, 3:45pm

Sorry for the late response, you could try ‘lsmod’ on both systems, I can’t guarantee that it’ll be helpful information but worth a go perhaps.

Looking at the bootup logs it seems to still be failing back to nouveau? (bold line)

Ah, yeah, see anything systemd gets involved with goes to pieces

I’m not at a computer at the moment but that mknod failure (creating a /dev entry for the device) seems like the culprit for sure. I just don’t know enough about boot time device management.

I wonder if adding debug to kernel options would give some more info.
