[SOLVED] System76 Gazelle 17 Graphics Switching

Hello, I recently purchased a Gazelle laptop from System76 which includes an integrated intel GPU and a discrete nvidia GPU

[jt@arch ~]$ lspci -k | grep -A 3 -e VGA
00:02.0 VGA compatible controller: Intel Corporation Alder Lake-P Integrated Graphics Controller (rev 0c)
	DeviceName: VGA compatible controller
	Subsystem: CLEVO/KAPOK Computer Device 866d
	Kernel driver in use: i915
	Kernel modules: i915
--
01:00.0 VGA compatible controller: NVIDIA Corporation GA107M [GeForce RTX 3050 Mobile] (rev a1)
	DeviceName: VGA compatible controller
	Subsystem: CLEVO/KAPOK Computer Device 866d
	Kernel modules: nouveau, nvidia_drm, nvidia
02:00.0 Non-Volatile memory controller: Samsung Electronics Co Ltd NVMe SSD Controller PM9A1/PM9A3/980PRO

I would ultimately like to be able to use the integrated GPU by default and use the discrete GPU for more intense tasks like 3D rendering or gaming. I would prefer to use nvidia's proprietary driver so I have access to CUDA. To take smaller steps I was trying to first get the discrete GPU working by itself. System76 has this page detailing how to install their software on other operating systems. I installed these packages:

[jt@arch ~]$ pacman -Q | grep system76
system76-acpi-dkms 1.0.2+4+gb49caa5-4
system76-driver 20.04.64-1
system76-firmware-daemon 1.0.23-1
system76-power 1.1.23-1

I have also installed these packages relating to graphics:

[jt@arch ~]$ pacman -Q | grep nvidia
nvidia 515.76-4
nvidia-prime 1.0-4
nvidia-utils 515.76-1
[jt@arch ~]$ pacman -Q | grep intel
xf86-video-intel 1:2.99.917+916+g31486f40-2

I am using gdm as my display manager, xorg as my display server, and i3 as my window manager. Even when I use system76-power to set the graphics mode to 'nvidia' and making sure that the discrete card's power is on it still doesn't seem to work. OpenGl applications such as blender or even glxgears to not work as they should. They seem to refuse to update: glxgears shows up but the gears don't move, and blender flashes between a grey screen and the startup screen when I move my mouse. The output of glxinfo is shown below.

[jt@arch ~]$ glxinfo | grep OpenGL
OpenGL vendor string: Intel
OpenGL renderer string: Mesa Intel(R) Graphics (ADL GT2)
OpenGL core profile version string: 4.6 (Core Profile) Mesa 22.1.7
OpenGL core profile shading language version string: 4.60
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 4.6 (Compatibility Profile) Mesa 22.1.7
OpenGL shading language version string: 4.60
OpenGL context flags: (none)
OpenGL profile mask: compatibility profile
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.2 Mesa 22.1.7
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20
OpenGL ES profile extensions:

When I try to run glxinfo with prime-run I get

[jt@arch ~]$ prime-run glxinfo
name of display: :1

and then it hangs there without stopping.

I have i915, nvidia, nvidia_modeset, nvidia_uvm and nvidia_drm in my MODULES in /etc/mkinitcpio.conf as suggested by this article.

This does not work though, and it causes my laptop to take a few minutes to boot. Here is the dmesg. It looks like something goes wrong around 4.114479.

I have tried to follow this article and this article as closely as possible, changing things where needed (some service names were outdated, etc.), but I am so lost.

If anyone has any ideas, I would really appreciate it. I would be willing to try anything at this point. If I missed any important logs or command outputs, let me know and I will post those.

Thanks,
JT

[    4.308542] traps: Missing ENDBR: _nv011438rm+0x0/0x10 [nvidia]

See the second point in the first note of NVIDIA#Installation.
After fixing that you may then hit https://bugs.archlinux.org/task/75995

Re: [SOLVED] System76 Gazelle 17 Graphics Switching

Alright, My /etc/default/grub looks like this now

# GRUB boot loader configuration

GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="Arch"
GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet nowatchdog ec_sys.write_support=1 acpi_os_name=Linux acpi_osi= nvidia_drm.modeset=1 ibt=off"
GRUB_CMDLINE_LINUX=""

# The resolution used on graphical terminal

GRUB_GFXMODE=auto

# Uncomment to allow the kernel use the same resolution used by grub
GRUB_GFXPAYLOAD_LINUX=keep

# Uncomment if you want GRUB to pass to the Linux kernel the old parameter

# documentation on GRUB_DISABLE_OS_PROBER, if still want to enable this

# operating systems.
#GRUB_DISABLE_OS_PROBER=false

and then I ran this

[jt@arch ~]$ sudo grub-mkconfig -o /boot/grub/grub.cfg

done

on reboot I did get a black screen, but ctrl+alt+2 let me switch to another tty. I set the system76-power graphics mode from 'nvidia' to 'compute' (intel normally, nvidia for certain applications) and rebooted. This time I saw my display manager properly and logged in. This time, prime-run glxgears worked and the gears were spinning! the same works for blender, and I can use CUDA to render! Everything seems to work! Thank you so much for pointing that part out on the nvidia page, I completely missed it.
