I was running Maverick very fluently, before I upgraded to Natty. However, the display performance seems fall down. For example, zoom desktop is very well in Maverick, but very slow in Natty.
I think it's caused by Unity. So I installed Gnome 3, using the source
deb http://ppa.launchpad.net/gnome3-team/gnome3/ubuntu natty main.
After installed Gnome 3, unfortunately it runs in fallback mode, and said maybe my graphics hardware is not supported.
$ lspci |grep -i vga 00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 10)
Should I have to upgrade my graphics card? The card is bought 2 years ago, though.
