If I insert the radeon module many things hang. In particular: if I start skype before I insert the module I cannot do calls anymore. If I try to start skype after inserting the module it hangs at the login. The same is true for "drive manager" and "audio and video settings" from systemsettings. Moreover vgaswitcheroo is unable to switch on the discrete card. More explictly, issuing echo ON > /sys/kernel/debug/vgaswitcheroo/switch the discrete card remains off.
