Best Answer

You can switch them this way:

sudo aticonfig --px-igpu

to the integrated adapter.

sudo aticonfig --px-dgpu

to the descrete adapter.

Log off and log on after that.

You can see the status by

aticonfig --pxl

You can also switch the adapters using Catalyst Control Center GUI utility.

Note: This should work on a supported Ubuntu version (14.04 or 15.10) and with the latest fglrx that can be installed by:

sudo apt-get install fglrx-updates
