Hello,

I've upgraded my ubuntu from 12.04 to 12.10 in AMD, radeon HD 3100 graphics card desktop. I'm on 32 bit Ubuntu installation.

I know unity2d would not be there, but I've read that there would be a lighter mode in unity, which would be automatically activated.

After solving my ati driver hell using ppa:makson96/fglrx, I still have to worst

1) Is there a way to have a lighter unity. Because as it is now, it is literally unusable. I love unity features and am really used to them, but can't stand the laggyness. I tried a suggestion, adding
Code:
export UNITY_LOW_GFX_MODE=1
to the file: /etc/X11/Xsession.d/99force-llvm . But I don't see any change.

2) If I bought a PCI graphics card, would it solve my problems? Is there any suggestions for a card?
