How can I switch between two GPU's on-the-fly using Ubuntu 11.04?
I have an Asus EEE1015PN intel N550 with two GPU's: GMA3150 and Nvidia ION2. For example Windows 7 will switch to the bigger CPU when I pull up a full HD movie.
You can use
One guy has written up a very detailed tutorial on setting this up under Fedora 14/Ubunut 10.10. You might have to adapt for 11.0, but it seems to cover the bases pretty well.
Ubuntu has documentation for using this on their wiki under HybridGraphics.
There is also a very useful overview of the process on the Gentoo wiki.
An experimental alternative system using ACPI is available from the Linux Hybrid Graphics blog which has instructions for checking out and running the toggle app for several different graphics chipsets as well as ongoing documentary of different models.
