I have ubuntu 12.04.2 and kde. I have fglrx 13.1 latest drivers. Sometimes I have freezes at starup, it's very annoying, and I discovered it's bug : http://ati.cchtml.com/show_bug.cgi?id=691 So maybe I should remove fglrx proprietary drivers and go back to mesa open drivers. The problem is: when I first tried open drivers my gpu was used to work at 70C° (158 Fahrenheit) instead I have max 39C° (102 Fahrenheit) with flgrx drivers. I think it's about temperature and fan control. If I decide to remove fglrx I want to be sure that I will not have problems, so I'd like to know:

  1. Is there a way to have same very good temperatures (like with fglrx drivers) with open drivers?
  2. Is there a good updated ppa to have latest open drivers versions in order to keep them updated?
  3. At this moment my plymouth works well with fglrx, is there any change I have to do to make it works with open drivers?
  4. Last question: do you think it's a good idea to use open drivers?

My machine specs:

  • gpu: msi/ati r6870 hawk
  • cpu: i5-2500k sandy bridge
  • motherboard: P8P67 PRO

Thanks a lot.

I will try to answer your questions in the same order.

1) Yes there is a way to decrease temperature with open-source driver (radeon). First you should try it from terminal with the following commands

    sudo su -

    echo low >  /sys/class/drm/card0/device/power_profile

    exit

After you confirm that the temperature decreased (check the output of sensors command), you can add the command echo low > /sys/class/drm/card0/device/power_profile to /etc/rc.local(before exit 0) to be executed in every reboot.

2) A good and "stable" PPA is considered this => Ubuntu X-Team

3) I think that plymouth is work well with radeon driver too.

4) IMHO yes. If we use the open source drivers and support them , then we will help the developers for a better release in future.
