My graphic on ubuntu 12.10 does not work as well as on 12.04.
After upgrade I installed driver
sudo apt-add-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get install nvidia-current
for my Nvidia 450 GTS graphics card.
But sometimes I see slight lag on my videos played in VLC player, some of desktop and window effects are lagging, sometimes I can see an indescribable souce of pixels on my screen at the start of ubuntu and so on.
Here is screenshot of startup screen.
I feel difference between 12.04 and 12.10 in favour of former version.
Does anyone know whats wrong or what I am missing?
