Hi Rocket2Dmn

I'm using the open source driver (fglrx doesn't support this older chip).

I got compiz working fine on Hardy with a similar workaround as to your well written howto. My issue is just with screen resolution.

System->Preferences->Screen Resolution doesn't offer any resolutions other than the native 1400x1050 for the laptop screen.

To troubleshot this a little further I borrowed an external monitor. Hardy had no problem identifying it and offering different resolutions, but still would not offer more than the native 1400x1050 on the laptop. The issue is limited to the internal laptop screen (which works fine on feisty).

I'm guessing there is a handshake when monitors are attached and the screen on this laptop either doesn't respond correctly or Hardy doesn't recognize the monitor type.

I've tried to force the resolution by manual edit of xorg.conf, but it is always overwritten. I will try grandr, next time I try the live CD.
