That's odd. What laptop was that? There really shouldn't be any reason for all but newest ATI GPUs to not work out of box. With nvidia the terrible stability and kernel upgrade hassles plus the need to externally install the drivers means it should be much uglier an experience than out of box ATI OSS drivers. Anyway as long as it works...

I have been using nVidia cards on Linux since the GeForce 2. I have never had any problems with their driver (apart from misconfiguration by me before X.org started autodetecting screens/GPUs and xorg.conf etc. was deprecated).

It's a small thing, but their binary drivers do not support kernel modesetting, so if I want to switch between X and the console it takes several seconds with a visible screen blank. Using nouveau (or anything that supports KMS) is very fast by comparison.

I found the open source driver situation to be quite good with AMD. I was able to play non-trivial games (TF2 and Dota2) and use two monitors quite well. In fact, the open source AMD drivers had better multi monitor support then either the proprietary or the community Nvidia drivers.

What kind of AMD chipset are you running? The HD 7000 series for instance was released early in 2012 and only started having _experimental_ and incomplete OpenGL support a year later. The performance was atrocious even 18 months after release and it likely still is. In the end I bought an Nvidia card which worked fine out of the box.

The AMD card I use is a 6870.

I had never noticed that but you are right! I thought it was normal....

And it still heats badly. The most important me as for the laptop Linux user was a comfortable temerature, which AMD failed to provide either way.

Have you tried enabling dpm? When enabled with a kernel parameter it dynamically changes the card frequency. I think you need a kernel version > 3.11. Check out: https://wiki.archlinux.org/index.php/ATI#Dynamic_power_manag... and http://www.x.org/wiki/RadeonFeature/#index3h2

I didn't yet. The best results I could possibly achieve were dynpm ones - about 65 degrees Celsius, which is completely unacceptable anyway. I've moved to a regular desktop PC, and I'm so happy for it ever since. Good to know though, that some improvement seems to be made. Thanks for that link!
