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 package.
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.
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.
