I have another problem with my HD 5770 ATI card.

It's fan all the time runs with the same speed (i think it's about 60% cause i dont know how to measure it on Ubuntu).

I have installed the drivers following this method

Even if i left my computer for three hours alone without any aplication runing, or watching video - every time it has the same speed.

I have dual boot with Windows 7 and there my graphic card fan is slow when i dont use PC and runs quicker if i start videos or games.

How to solve this problem?

I read that i can set fan speed to custom value, for example 30%, but how to make it to control automaticaly by the drivers. Thanks. (Sorry for my english, im not from english speaking country and it's hard for me to speak it)

You have installed the right drivers but using a method that is not for your Ubuntu version.

For more information on how to install, remove and revert drivers please follow the link to this question

If you have installed the proprietary drivers and there is a problem with the fan speed you need to report that to AMD as a bug in the drivers.

As a workaround for that you might want to set a lower power state using the aticonfig tool. Set it on a console using this command:

aticonfig --set-powerstate=1

To find out which powerstates your Radeon supports try:

aticonfig --lsp

You can take a look at this answer here, solving the problem changing the profile of the open source ati driver that you are using and installing Jupiter, which is an applet to control the performance of your video card, battery consumption, etc. There is also a bug for this problem, you can find it in the answer above.
