PRIME detects both cards and automatically selects Intel card by default; using the more powerful discrete graphics card, when called, for more demanding applications. | |||
In Manjaro this will automatically be available for hybrid graphics systems using intel/modesetting for the integrated card and free drivers (AMDGPU or Nouveau) for the dGPU. | |||
For an application to use the dGPU with free drivers prepend the application command with '''DRI_PRIME=1'''. For example: | |||
DRI_PRIME=1 glxspheres64 | |||
Manjaro also offers an easy way to use PRIME with proprietary Nvidia drivers.<br> | |||
Simply select and install an 'nvidia-prime' profile through MSM or mhwd (such as ''video-hybrid-intel-nvidia-440xx-prime'') and ensure the package ''nvidia-prime'' is installed. | |||
Then to use the discrete Nvidia card prepend the application command with '''prime-run'''. For example: | |||
prime-run gimp | prime-run gimp | ||
If you want to | If you want to always run some application with the discrete gpu, you may copy that application's .desktop file to {{ic|~/.local/share/applications/}} and edit the "Exec" property | ||
Exec=prime-run firefox | Exec=prime-run firefox | ||
