I am not anything like a gamer so a modern Integrated graphic card should be more than enough for me but after getting a new PC with Sandy Bridge CPU (Intel core i7 2600K) I've had very shaky display on Ubuntu 10.10: Flickering screen and random red pixels whenever there are black color on the browser. My Motherboard is Asrock h67m.
As per suggestion here, yesterday I upgraded my Ubuntu to 11.10. Not seen flickering screen yet but the random red pixels still show up on browser.
So I am wondering whether it is a likely solution to apparently existing) Linux graphic issues with Sandy Bridge processors if i get an Ubuntu-friendly graphic card. And If so, what cards have shown good fidelity with Ubuntu?
Here is my Ubuntu 11.10's ispc result:
