I'm using Ubuntu 12.10 Quantal, on my dodgy Vostro 1400 with Nvidia GeForce 8400 GS.
Since installation, I switch to Nvidia driver and it works alright, but the windows performance is choppy, especially windows animation effects. Disabling Sync to VBlank and compression make it works a bit smoother, but still unacceptable. At least there are no screen tearing and stuff.
I decide to give Nouveau driver, holy god the windows compiz effects are smooth butter. I was happy til I open the Dash, when I realised the screen tearing all over, unless I close Dash. The
libgl1-mesa-dri-experimental package does not help.
Anyway to fix the screen tearing?
