If your hardware includes more than one GPU card and you are using the free drivers (video-linux), 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 use the second card with Gimp | |||
DRI_PRIME=1 gimp | |||
To use the 1st card (usually when the CPU has an embedded GPU, this is used) | |||
DRI_PRIME=0 gimp | |||

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.

So, bumblebee detects both cards and automatically selects Intel card by default, while uses Nvidia for more demanding applications. | ||
