All PRIME configurations require setting the PCI bus IDs of the two GPUs. One easy way to do find their IDs is by running <code>lspci</code> from the <code>pciutils</code> package, and then finding devices that are classified as VGA controllers. After double checking that the listed devices are indeed your integrated and dedicated GPUs, you can then find the PCI IDs at the beginning of each line. Exact results may vary, but an example output might look like:<syntaxhighlight lang="console"> | All PRIME configurations require setting the PCI bus IDs of the two GPUs.
