Unable to switch from Nvidia to Intel about system76-power

[mbeltagy]

I got the following advice from System76 customer support and it worked quite well for me

Let's reinstall the NVIDIA Driver with these commands:

sudo apt purge nvidia* && sudo apt autoremove
sudo apt update
sudo apt install system76-driver-nvidia
reboot

If that doesn't fix the issue we can reinstall the packages and then test again:

sudo apt install --reinstall gnome-shell-extension-system76-power system76-power

[melroy89]

I'm also unable to switch between Intel <> Graphics (first time it tried it, and worked actually (although PopOs gave an error it was unable to switch to Intel Graphics, since I saw the led icon change on my laptop.. but from that moment on I'm unable to switch at all).

Log (same log as journalctl /usr/bin/system76-power) :

Anything mentioned in journalctl /usr/bin/system76-power?

[8bitbuddhist]

Here's the output of journalctl since the last reboot. Nothing really sticks out at me. I also checked /etc/modprobe.d/system76-power.conf and it looks correct

[jackpot51]

Are you running Ubuntu or Pop!_OS?

[8bitbuddhist]

Pop!_OS, using the 18.04 ISO (I believe it was the Nvidia ISO, but I'm not 100% sure)

Also experienced this issue when trying Pop!_OS on my MSI GE40 with Optimus GTX 760m and Intel I7-4702MQ graphics.

Tried Mint 19 and the exact same thing is happening. Looks like this is more an issue with the Ubuntu 18.04 base.

To be more specific in my case, I use either distro's built in tool to switch to intel/power saving graphics and restart when prompted. The laptop boots up with everything running fine but with the nvidia gpu still running. I can tell as the indicator LED on laptop stays orange (it goes blue on intel graphics) and the laptop continues to pull far more wattage and generate a lot of heat.

[drNoob13]

I happened to have the same issue after running latest updates from system76. Mine is Ubuntu 18.04, Oryx Pro 2018.

[8bitbuddhist]

There do seem to be several issues surrounding this in Ubuntu, not Pop:

https://bugs.launchpad.net/ubuntu/+source/nvidia-prime/+bug/1765363
https://bugs.launchpad.net/ubuntu/+source/nvidia-prime/+bug/1757180

My "solution" was to disable the GPU in BIOS and force Pop to use the Intel card, which isn't ideal but works for now. Hopefully there will be an upstream fix soon

[drNoob13]

Can you please keep this open until there is a solution rather than disable GPU in BIOS?

[8bitbuddhist]

Can you please keep this open until there is a solution rather than disable GPU in BIOS?

I agree disabling the GPU isn't a real solution, but from what I've seen in my searching, this is an Ubuntu problem and not a Pop problem

[drNoob13]

I am able to switch between Intel and Nvidia GPU after turning Turbo Boost back on (or reset BIOS to default). Do it and try:
$ sudo system76-power daemon

[drNoob13]

switched to Intel GPU. nvidia GPU was turned off.

[tchar]

Hello Guys.

I have the same problem and I also run PopOs 18.04.
Turning to Intel (from Nvidia) does not work neither with gnome-shell-extension nor with the command sudo system76-power graphics intel.

Should you need any other info about my system please tell me

[fmarier]

I filed #76 for the problem that @tchar and I are seeing.

[mbeltagy]

I have the same problem on my Oryx Pro. I am now totally locked in NVIDIA.

[toefel18]

I have the same problem. And the laptop gets really hot and makes a lot of noise

[krthkj]

Following error keeps appearing and by looking at the code, seems like the fan hwmod for laptop is not configured. I suspect this may be the reason for fan noise and laptop heat.

[INFO] Adding dbus path /com/system76/PowerDaemon with interface com.system76.PowerDaemon

[toefel18]

I also did those commands and that fixes it for a couple of times, but sometimes is breaks again. My set-up also logs:

Wondering if that fan daemon: platform hwmon not found causes problems

[mmstick]

Wondering if that fan daemon: platform hwmon not found causes problems

This is normal on systems without a platform hwmon

[neurolabusc]

I also have this issue with my Oryx Pro running PopOS. Our other Oryx Pro burned out its NVidia graphics card, so I would really like to only use the GPU when I need CUDA. Further the NVidia GPU seems to cause the fan to run at a constant loud setting, which is not good for a quiet office nor good battery life. Any news on a fix? I upgraded the ROM but this has not helped.

[crawfxrd]

Is anyone able to reproduce this issue?

Both nvidia and nouveau are blacklisted in Intel mode via /etc/modprobe.d/system76-power.conf, so I'm interested in knowing which set is loaded (and how).

[realashishdave]

I had the same problem and I solved it. Edit /etc/default/grub and replace quiet splash with nouveau.modeset=0 and then run sudo update-grub and now reboot the system. You'll have now Intel graphics. To switch Nvidia vice versa this process

[sjatkins]

All of the above is in my mind workarounds for something obviously quite broken. If I had realized this system had such hybrid grapbics that are known to have problems from when I first run into them when converting windows machines to linux years ago I would never have purchased it. It is not just pop!OS but it is a bad way to do things. I can't even run an external monitor on my lovely maxed out Adder without switching to nvidia which of course runs fans loud continuously. I am very disappointed.

[ZacharyRSmith]

I also could not change from NVIDIA to Intel. Then, I ran all my updates. Then, I was able to change from NVIDIA to Intel. I'm guessing due to an OS update.

[crawfxrd]

If this is still an issue on the latest system76-power and nvidia-graphics-drivers, please open a new issue.
