DRI_PRIME=1 | If your hardware includes more than one GPU card you can make use of PRIME offloading. PRIME is a technology used to manage hybrid graphics found on recent desktops and laptops (Optimus for NVIDIA, AMD Dynamic Switchable Graphics for Radeon). 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. | |||
You may choose to run a program with a specific GPU, prepending the application's command with ''DRI_PRIME=x'', where ''x'' is the card priority number. | |||
For example, to run an application using the second card prepend the application command with '''DRI_PRIME=1''' | |||
DRI_PRIME=1 glxspheres64 | |||

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=DRI_PRIME=1 inkscape | |||
Some applications (usually games like steam) may have an embedded option to specify the command line, where it is preferred to use this way. | |||
For example, in Steam, select a game - that you want to run using your discrete Nvidia card - from the Library page of the Steam client, right-click, and select Properties. | |||
Click the SET LAUNCH OPTIONS... button and specify for the command line options followed by the default launch hook %command%. | |||

For Legacy/older nvidia cards, Manjaro maintains older drivers for compatibility. In these cases the driver name is different, instead of nvidia it is nvidia-390xx or nvidia340xx, whether in nvidia-only or bumblebee mhwd driver configuration. | For Legacy/older nvidia cards, Manjaro maintains older drivers for compatibility.

When you install Manjaro with the non-free option selected from Grub menu, or when you use automatic driver installation, bumblebee is installed by default. In these cases, the mhwd driver is named "video-hybrid-intel-nvidia-bumblebee". | When you install Manjaro with the non-free option selected from Grub menu, or when you use automatic driver installation, PRIME or bumblebee is installed by default, depending on support for your GPU, PRIME being preferred. In these cases, the mhwd driver is named "video-hybrid-intel-nvidia-***xx-prime" or "video-hybrid-intel-nvidia-***xx-bumblebee". | ||
