Δεν είμαι απόλυτα σίγουρος πως το πιο πάνω ισχύει:

Σύμφωνα με την ιστοσελίδα phoronix, το powerxpress υπάρχει στο Catalyst 11.4. Αυτή η έκδοση πρέπει να είναι ήδη στο ubuntu από το 11.04. Άρα εγκαθιστάς το fglrx driver (ψάξε για πρόγραμμα "additional drivers" ή "jockey").
Επίσης εγκαθιστάς το πακέτο fglrx-amdcccle αν δεν το έχεις κάνει ήδη.
Δεν ξέρω αν δουλεύει όμως.

With PowerXpress in the binary driver, not only does the server need to be restarted, but the OpenGL and GLX libraries need to be flipped out too. With vga_switcheroo on the open-source drivers, there is no switching needed since they all use the common Mesa libGL, but between Intel and AMD graphics with Catalyst, it requires flipping between Mesa and AMD's proprietary OpenGL implementation.
This switching also doesn't happen like it does under Windows when either connecting or disconnecting from an AC power source, but it must be initiated by the user.
