I've been searching like crazy trying to find a fix for this, it's the only thing that's not completely working on my setup. I see posts where people say it should be working but it just isn't. I have a Gateway LT2802u netbook and I installed 11.10 on this 2 days ago. Everything works except for accelerated graphics. At first I couldn't watch a simple flash video at all, but somehow I got it to work. Now the last problem I have is I can't watch HD videos, my screen resolution won't go higher than 1024x600, and my under my graphics driver it says "Unknown".
After doing as much research as possible, I've come to the conclusion that it's the GMA 3150 graphics driver. There is a bunch of talk on it all over the interwebs but nothing lately. I've tried the fixes that some people have used but most when I try to get the package it's no longer there or available if that makes sense. I'm loving everything Ubuntu has to offer but it'll really bite if I can't use it any more because of this problem. Does anybody have any ideas? You'd really be helping a lot.
