Unless someone could port over the gpu-manager. Which doesn't seem hard, I just doesn't have a NVIDIA hybrid computer to test this on. I don't think messing with people's X11 config in a hacky way would be a great idea. I've added a note when installing the package to mention this issue. If there's something I missed please let me know.

Also, even if gpu-manager is ported, I'm not sure if it should be set as a dependency, since non NVIDIA users have no use for it (it seems)

I couldn't get gpu switching on my Adder WS to work properly until I added the X11 config file described here.

According to the system76-power maintainer system76-power relies on gpu-manager provided by Ubuntu to generate these configs. It would be nice if there'd be a way to generate the appropriate configs for this package too.

Edit: I see others have already pointed this out. Anyway, maybe investigating gpu-manager would point to a general solution.

@jcsanyi I tried what you suggested it did not work. The intel mode works perfectly but nvidia mode does not. Somehow /etc/X11/xorg.conf.d/10-nvidia-drm-outputclass.conf got removed on reboot or mode switching!

In intel mode, I verified that the nvidia card is powered down, as there is no entry related to nvidia card in the output of powertop. In the nvidia mode I can see that nvidia card is powered on, in the powertop output but glxinfo | grep -i "OpenGL renderer" shows:

OpenGL renderer string: Mesa DRI Intel(R) UHD Graphics 630 (Coffeelake 3x8 GT2)

Also I could not launch nvidia-settings in nvidia mode.

@tachyon - This works for me with the standard nvidia drivers. I'm on a current gazelle (gaze14) laptop.

Make sure you've added the PrimaryGPU configuration option described here: https://wiki.archlinux.org/index.php/NVIDIA_Optimus#Use_NVIDIA_graphics_only

It's not well documented, and broke sometime in the last few months. See here for more details: https://bbs.archlinux.org/viewtopic.php?id=251846

Can someone tell me which graphics driver to use to make it work? Right now only switching to intel works. But switching to nvidia does not work without prime. In prime mode I can only run individual applications on nvidia card but cannot drive the entire display. So basically my external HDMI and display ports are useless now.

Works perfectly for me now, thanks!

done, I have made it so it does not requre git anymore (downloads tar.gz instead), and also added a patch. Please see if it works now.

I was unable to build this package (in a clean env) until I added 'git' to the 'makedepends' list. Can you update the PKGBUILD?

When changing the graphics mode, the daemon updates the mod configs, and then tries to run "update-initramfs -u" to rebuild the initram. On arch, this command does not exist, and the functionality is provided by mkinitcpio instead.

As a temporary workaround, I created a shell script named "update-initramfs" that's just hard-coded to call "mkinitcpio -P", and it now works as intended... but this is a rather unsafe hack, as it completely ignores the parameters passed to the update-initramfs command.

Is this something we should/could be patching as part of the PKGBUILD? It looks like a fairly simple change here: https://github.com/pop-os/system76-power/blob/master/src/graphics.rs#L298

When I run "system76-power graphics"

It returns:

daemon returned an error message: "The name com.system76.PowerDaemon was not provided by any .service files"

How to deal with this problem?
