## DESCRIPTION

update-glx is a wrapper around update-alternatives supporting only configuration of the 'glx' and 'nvidia' alternatives. After updating the alternatives, it takes care to trigger any follow-up actions that may be required to complete the switch.

It can be used to switch between the main NVIDIA driver version and the legacy drivers (eg: the 304 series, the 340 series, etc).

For users with Optimus-type laptops it can be used to enable running the discrete GPU via bumblebee.
