ACER Intel-NVIDIA GPU not displaying on external monitors

English Hardware

Hi Folks,
I’m trying to reinstall TW on an ACER Predator PH315-54 laptop that has 2 GPUs.

The problem I’m encountering is that I have the laptop display as well as 2 external
monitors (1xHDMI and 1xUSBc), but I cannot get output on these 3 displays.

This worked in the past (about 2y ago) and it still works on the windows boot.
I’m using KDE and I’ve tried both X11 and Wayland; NVIDIA driver installation from the suse nvidia repo the easy way & the hard way from SDB:NVIDIA drivers,
as well as by using NVIDIA’s .run installer – all with similar results.

I read through several related posts, but after trying a number of suggestions there, I’ve not made any progress. Notably, the end of post https://negativo17.org/prime-optimus-laptops-and-multi-gpu-systems seems to suggest rolling back to an earlier rev of the NVIDIA drivers?

Any suggestions on how to proceed?

Here is some info:

I hope that isn’t TMI and is useful info.

@bcain Hi so iGPU doesn’t have a kernel driver in use?

Device-1: Intel TigerLake-H GT1 [UHD Graphics] vendor: Acer Incorporated ALI
    driver: N/A

You should not be using or have installed anything suse-prime, bumblebee or bbsitch related.

3

@malcolmlewis , Ummmm. I guess not? I gather it should…so what do I do have to get me one? Acer supports windoze but not linux…
BTW…I fiddled with suse-prime, bbswitch and bumblebee when things didn’t work out of the box, but I think I have since purged them.

4

@bcain just check to make sure they are gone. Also as root user run lsinitrd | grep -E "nouveau|nvidia|bbswitch" to check.

5

Opps, you were correct, there were some squirrled away:

-rw-r--r--   1 root     root          129 Feb  4 12:17 usr/lib/modprobe.d/09-nvidia-modprobe-bbswitch-G04.conf

-rw-r--r--   1 root     root            9 Feb 22  2024 usr/lib/modules-load.d/bbswitch.conf

There were many other nvidia entries returned as well.
So, how do I remove these entries…would it be:
sudo modprobe -r “usr/lib/modules-load.d/bbswitch.conf”
etc.?

Are the intel drivers for this GPU provided by the Amber-Mesa package?
Have a nice evening,
Brad

@bcain so you if you run dracut -f --regenerate-all and reboot are they gone?

If not manually remove the following with, for example rm -f /usr/lib/modules-load.d/bbswitch.conf, rebuild initrd with the above command and reboot.

09-nvidia-modprobe-bbswitch-G04.conf
09-nvidia-modprobe-pm-G05.conf
50-bbswitch.conf
bbswitch.conf

No your intel GPU is fine it supports the Xe driver as well…

7

Morning @malcolmlewis,
I think that I have removed the offending entries; I assume the remaining NVIDIA entries are desired?

lsinitrd | grep -E "nouveau|nvidia|bbswitch|bumblebee"
-rw-r--r--   1 root     root          131 May 21 08:47 etc/modprobe.d/nvidia.conf

Currently, I have my laptop display, although there is only 1 resolution mode available, and the HDMI display seems recognized, but only the mouse pointer is visible, not the desktop screen. The USBc display is not active.
I still don’t see an intel driver listed, but is that expected?

Hi @malcolmlewis ,
I did some more searching and discovered that I had left a nomodeset option in the linux boot command…removing that and rebooting has all three of my displays showing normally.
Thanks for all your help!
Cheers,

brad
