.SH 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.
