SDB:NVIDIA SUSE Prime
SUSE Prime is a tool used for switching between integrated Intel GPU and NVIDIA GPU on Optimus laptops. It is alternative to Bumblebee.
With SUSE Prime setup, all applications render either on Intel or on NVIDIA. You can switch between them using a prime-select tool. Log-out and log-in is required for the change to take effect.
You have Optimus laptop and want ability to switch between NVIDIA and Intel GPUs.
- Install the NVIDIA proprietary driver: SDB:NVIDIA drivers
- Make sure you have no /etc/X11/xorg.conf file and no configuration files with "ServerLayout", "Device" or "Screen" sections in the /etc/X11/xorg.conf.d directory. (Clean installation fulfills that.)
- Install the suse-prime and bbswitch-kmp-default packages.
To switch between Intel and NVIDIA, run as root:
# prime-select nvidia
# prime-select intel
Then log out and log in to apply the changes.
Please note: if you have an Optimus laptop, there are additional steps required to make sure the nvidia card is powered off. A systemd service needs to be installed.
Please see https://github.com/openSUSE/SUSEPrime
To verify which GPU is in use, you can compare the output of following commands:
# xrandr --listproviders Providers: number : 1 Provider 0: ... associated providers: 0; name: modesetting
# glxinfo | grep 'OpenGL renderer string' OpenGL renderer string: Mesa DRI Intel(R) Ivybridge Mobile
# xrandr --listproviders Providers: number : 2 Provider 0: ... associated providers: 1; name: NVIDIA-0 Provider 1: ... associated providers: 1; name: Intel
# glxinfo | grep 'OpenGL renderer string' OpenGL renderer string: GeForce GT 640M LE/PCIe/SSE2
How does it work?
The prime-select script modifies two things in the system:
- Switches the X server's GLX extension between the original and NVIDIA implementations.
- Copies either /etc/prime/xorg-nvidia.conf or /etc/prime/xorg-intel.conf into the /etc/X11/xorg.conf.d directory.
When the Intel option is selected, the X server is configured to completely ignore the NVIDIA card. The NVIDIA driver will keep it sleeping.
When the NVIDIA option is select, X server will use both cards - NVIDIA for rendering and Intel as output provider. The configuration of output provider is done automatically by the X server on start.
Customizing the configuration
If you need change the "Screen", "Device" or "ServerLayout" sections of X configuration, make you changes in the /etc/prime/xorg-nvidia.conf or /etc/prime/xorg-intel.conf files.
Any other sections (e.g. input device configurations) can be done in files in the /etc/X11/xorg.conf.d directory.
If Nvidia driver not activated on login (if you choose it), you are probably using Wayland Protocol. To verify what X server you're using:
# loginctl SESSION UID USER SEAT TTY 1 1000 youruser seat0
# loginctl show-session 1 | grep Type Type=x11
if it's wayland and not x11, you're using Wayland.
To configure system to use X11:
Maybe you'll encounters some tearing problem with Nvidia activated. To get rid of this, you must activate the "PRIME Synchronization".
create the file
and insert the line
options nvidia_drm modeset=1
then use command
# sudo dracut -f
Installer freezes on optimus laptops
1. Boot Laptop with openSUSE Tumbleweed live USB/DVD.
2a. If you are installing using UEFI, move down to select "installation", press "e" to edit grub entry called "installation". Find the line that starts with "linuxefi /boot/vmlinuzxxx", move after "splash=silent" and add the following (without brackets) "nomodeset". Press F10 to boot. Note that the installer no longer hangs.
2b. If you are installing using legacy BIOS boot, move down to select "installation", press "F5", move down to select "nomodeset", press enter to confirm. Note below "F5 Kernel" now it shows "nomodeset". Hit enter to begin installation. Note that the installer no longer hangs.
3. Install openSUSE Tumbleweed.
4. Update repos and upgrade system:
$ "sudo zypper ref && sudo zypper dup".
5. Reboot the system.
6. Remove the nomodeset kernel option.
find the line starting with
7. Update grub.
sudo grub2-mkconfig -o /boot/grub2/grub.cfg
8. Proceed with nvidia driver installation per official documentation: https://en.opensuse.org/SDB:NVIDIA_drivers
9. Proceed with suse-prime installation and testing per official documentation: https://en.opensuse.org/SDB:NVIDIA_SUSE_Prime
10. Reboot system
