I have a laptop with both AMD Raven and Nvidia GTX 1050 video adapters. I wanted to test the new game mode in Ubuntu 20.04, and noticed that only the AMD Raven actually works. To do the test, I tried launching a terminal and running gxgears, both in a normal way, and then using the “start using dedi…

Actually, I’ve just found out that adding “Option “PrimaryGPU” “Yes”” to /usr/share/X11/xorg.conf.d/10-nvidia.conf made the 3D acceleration (and nvidia-settings) work! However, now, I have no way to switch between AMD Raven and GTX: it always uses the GTX.

No, it doesn’t change a thing. Actually, the only way, for me, to switch between AMD and NVIDIA is by enabling / disabling Option “PrimaryGPU” “Yes” in /usr/share/X11/xorg.conf.d/10-nvidia.conf, and then restarting. PS: just to be sure, is there a good way to know which adapter is being used? I us…

It’s the correct way to check which gpu gets used. When switched to intel mode, the nvidia gpu should normally be powered off and the nvidia drivers are blacklisted. Please run nvidia-bug-report.sh as root and attach the resulting nvidia-bug-report.log.gz file to your post. You will have to rename t…

Please try installing bbswitch. Also, please make sure gpu-manager is enabled (sudo systemctl enable gpu-manager) and attach /var/log/gpu-manager.log

Sorry, but i have no idea how to install bbswitch (neither do I know what it’s for, by the way) on Ubuntu 20.04. Could you give me hint, please?

bbswitch is a kernel module to power off the nvidia gpu. Use sudo apt install bbswitch to install it.
