GPU overheating with the open source radeon driver
This was an annoying problem with the open source drivers, since kernel 3.11 and up things have improved a lot. There are 3 different methods to handle power management:
- dynpm
- dpm
- profiles
The profiles are static, you need to set them manually which is a hassle, dynpm is dynamic but causes flickering. Dpm is new since kernel 3.11 and I'm having pretty good results with it.
To enable it:
Open a terminal.
First you need to set a kernel parameter, this will tell your kernel it needs to enable dpm
sudo nano /etc/default/grub
there you need to add "radeon.dpm=1" to the kernel line in your grub config:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.dpm=1"
Press Ctrl-X to save, choose 'Y' to overwrite.
Now you need to generate the new grub config:
grub-mkconfig -o /boot/grub/grub.cfg
You can use 3 profiles for dpm:
- battery
- balanced
- performance
Balanced is the most useful one. To enable it:
again in the terminal:
sudo nano /etc/rc.local
add the following line in this file ( above the line that says "exit 0":
echo balanced > /sys/class/drm/card0/device/power_dpm_state
Save the file and reboot your pc.

I recently installed Ubuntu 13.10 on my desktop and would really like to keep using the open source drivers for my RadeonHD 6970 graphics card. However, during boot and after startup, the GPU temperature immediately gets hot and hovers around 76°C (with a fan blowing loudly)
The fglrx driver does not have this problem, but I don´t want to use that for other reasons.
Is there a way to configure or fix the Radeon open source driver so the temperature stays low until I actually start heavily using the GPU performance? My experience with Ubuntu/Linux is limited, so please explain any solution very carefully.

mahler over 10 yearsThanks! The explanation was excelent. Too bad this needs to be done manually, but it helps a bit. The temperature stays at 63°C now. Not as good as the fglrx, but definitely an improvement. The fan is also a lot less loud. If you upvote my question, I might have enough reputation to upvote your answer.

boombanana over 10 yearsHappy to help. Also check for dust in the fan. I'm getting 57°C with the balanced profile on a HD5600 with my laptop. Question upvoted ;)
