I installed Ubuntu 10.10 alongside Ubuntu 11.10 to use an older version of Compiz. On Ubuntu 11.10, Compiz was enabled by default and I didn't need to use any graphics driver to enjoy the effects. All I had to do was install CompizConfig Settings Manager and enable those extra effects. That was Compiz 0.9.6.

Now, after installing Ubuntu 10.10, when I first logged in, the graphics were slow. When I dragged a window from one end of the screen to the other, the whole screen would blur up and pixelate and it would be very laggy. I tried going to System > Preference > Appearance and selecting Extra effects on the Visual effects tab, but all I got was "Desktop effects could not be enabled".

I don't know whether I should install the Additional drivers (proprietary) because my Internet is slow and it would take a long time. Furthermore, in Ubuntu 11.10, after I installed the proprietary graphics driver, I immediately went into fallback mode and wasn't even offered an option to set my desktop session to Ubuntu 3D. I didn't need the driver to run Compiz in Ubuntu 11.10, it just ran so smoothly. But in Ubuntu 10.10, everything is so laggy.

Should I install the ATI/AMD Proprietary FGLRX Graphics Driver for Ubuntu 10.10 to enable extra effects? Or is there something else wrong with my system?

Here is the output of

lspci -nn | grep VGA

00:02.0 VGA compatible controller [0300]: Intel Corporation Sandy Bridge Integrated Graphics Controller [8086:0116] (rev 09) 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc Device [1002:6760]

Here is the output of the same command, but in Ubuntu 11.10 (in this case the one which is correct, because I don't have the Sandy Bridge Integrated graphics controller)

00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0116] (rev 09) 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc NI Seymour [AMD Radeon HD 6470M] [1002:6760]

you've got dual intel ati graphics - do a quick search here for vgaswitcheroo –  fossfreedom Nov 27 '11 at 9:15
    
How am I going to solve my problem with that? @fossfreedom –  jasoncruz98 Nov 27 '11 at 9:31
    
So you could switch to the AMD card and install the drivers to have more complex compositing –  Uri Herrera Nov 27 '11 at 9:51
    
@UriHerrera Can you please post how to switch to the AMD card and install the driver in the answer? –  jasoncruz98 Nov 27 '11 at 10:52
    
Are you still experiencing this issue? –  jrg Mar 5 '12 at 18:39
