Well, Xserver doesn't crash on startup with fglrx installed as it used to do before, and I can use AMD card with them. I can switch graphic cards from catalyst control panel, but for some reason, there is no direct rendering when I switch to Intel. But I realy don't care, while AMD card works with fglrx without a problem. Kernel is 3.2 on that laptop. And btw, in BIOS there is only option to turn switchable graphics on/off.
It is not switching like in win7, you need to logout/login after switching from catalyst control panel.
Well so much for wishful thinking. Mine don't work. Intel SB + AMD 6470M. Kernel is .38-13 on Natty. This sux!
