The ATI proprietary drivers on my laptop on Linux for some reason result in my computer not shutting down properly; I have to force shutdown and that's no good to me for my case. Though the driver loaded does not match the exact card model, only the closest equivalent.
Give the opensource ati driver a try. Fglrx has sucked for a while, even to the point of not being able to do compositing without modifying a bunch of system files.
the Intel chip lags horribly in heavy work, can't play games and it screws things up horribly when going into projector mode, video streaming sites take a total crap and irritating screen switching with the resolution also taking a crap among other things (I've done project presentations on it, it sucks to take the flak from the Windows/Mac masses, but that's the life of it), but in normal use it's better.
I think it's just the fact that it's an intel chip period. They are made for pretty basic things when it comes with a motherboard. The intel chip in my netbook was really tossed in there strictly for meager desktopping and for watching dvd's. It's just the fact that it's pretty ok at playing games like openarena at medium settings was pretty cool for what it can also get away with (netbook is good for older games).
What makes me happy about a driver going opensource is that it gets included in the linux kernel. When it gets included in the linux kernel, that's another device that fits the description of "works right out of the box" with linux. So, you can imagine how much i love the ati and intel opensource drivers because after i'm done installing linux, all my hardware really is working without needing to grab extra drivers. Opensource ati drivers are cool even further, i believe it works on a one driver works for all ati cards basis (no planned obselescence, they're going to go ahead and have compatibility for older ati cards too). I know for the new nouveau nvidia opensource driver that's how it is (i still use the nvidia proprietary driver still because nouveau isn't what i'd consider usable right now).
I've been pretty happy with nvidia for a while. I use to use ati after nvidia bought 3dfx. Ati wasn't much to balk at during the day until the radeon 9xxx series came out (those were good). And then ati pretty much dropped the ball with radeon x300 x400 x800 etc(the next gen radeon cards after the 9xxx series). The geforce 6 and 7 series were spectacular for performance and price back in the day. Also, because nvidia was way better for running linux with for a long time. Before the ati opensource driver, you had the nvidia and ati proprietary drivers. The nvidia proprietary driver was and still is that much better than the ati proprietary driver.
To recap, the ati driver going opensource is awesome, this means that ati is now an actual solution for 3d acceleration under linux whereas previously it was mediocre and now ati people can hold something pretty major over nvidia people (opensource driver being it). For nvidia, there's the proprietary driver which is still a really good and made nvidia a long time the preferred choice for compatibility and 3d acceleration under linux (still a good solution it is, and it works great, but i want the nouveau driver to mature so i don't need to rely on the proprietary driver anymore).
It's good to know ati picked up the ball again in two areas instead of just one (gaining better performance than nvidia and opensource driver).
