Hello I am using Ubuntu 11.10 with Gnome 3 installed. I have issues with the fan (I know that there are many threads about this but nothing has worked).

I am using Dell Studio XPS 1640 running core2duo 2.67Gz intel processor and Ati radeon hd (mobility) 4670. If you need anymore specs, please let me know.

I just installed Ubuntu again trying to get everything sorted out. I then imediately updated:

sudo apt-get dist-upgrade

And then I install gnome 3

sudo apt-get install gnome-shell

Then I DID NOT install the proprietary drivers provided by ATI because I know that they are incredibly unstable with Gnome 3 (plus a ton of errors that I lived with on Unity for about 2 months including screen tearing, half the screen doesn't draw/update and lots of crashes).

The ui is smooth and fast with the open source ati drivers (installed when Ubuntu was installed). I then tried to reduce the fan by installing Jupiter:

sudo apt-get install jupiter

And CPU freq

sudo apt-get install indicator-cpufreq

And running sensors:

sudo apt-get install lm-sensors
sudo sensors-detect

I also read that I was suppose to run fancontrol

sudo pwmconfig
sudo fancontrol

However running pwnconfig gives me this output

/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed

So naturally fancontrol doesnt work.

After this, the fan is always on. I set the pc to powersaving mode and still always has the fan on. Typing sensors in terminal gives me this output

acpitz-virtual-0
Adapter: Virtual device
temp1:        +56.0°C  (crit = +100.0°C)
temp2:        +46.0°C  (crit = +100.0°C)
temp3:        +60.0°C  (crit = +100.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Core 0:       +51.0°C  (high = +105.0°C, crit = +105.0°C)
Core 1:       +51.0°C  (high = +105.0°C, crit = +105.0°C)

radeon-pci-0100
Adapter: PCI adapter
temp1:        +61.0°C

Which my radeon temperature is always around 60 (even cold boot). I go to my Windows 7 partition and the fan dies down quickly. I boot back to Ubuntu from shutdown and once the login screen comes up, the fan is on and loud (even if the laptop was cold from external temperatures). Also there is no option in bios to limit the fan speeds.

Furthermore, I have also done the steps listed on this webpage: http://javacolors.blogspot.com/2011/10/ubuntu-1110-ati-radeon-deal.html

Is there any other methods without installing the ati proprietary drivers to solve this fan solution?

I'd struggled with this problem during two weeks. I'm using desktop and ati 5770.

Opensource 'radeon' driver has some power management feature via adjusting gpu clock, but it didn't works very well.

Here is good article about radeon and fglrx power management.

The Current State Of Radeon Power Management

This is my alias for opensource radeon power management.

# radeon gpu power management
alias profilepm='sudo bash -c "echo profile > /sys/class/drm/card0/device/power_method"'
alias auto='profilepm && sudo bash -c "echo auto > /sys/class/drm/card0/device/power_profile"'
alias low='profilepm && sudo bash -c "echo low > /sys/class/drm/card0/device/power_profile"'
alias mid='profilepm && sudo bash -c "echo mid > /sys/class/drm/card0/device/power_profile"'
alias high='profilepm && sudo bash -c "echo high > /sys/class/drm/card0/device/power_profile"'
alias dynpm='sudo bash -c "echo dynpm > /sys/class/drm/card0/device/power_method"'
alias gpu="sudo cat /sys/kernel/debug/dri/0/radeon_pm_info /sys/class/drm/card0/device/power_method"

First select default method.

  • profilepm for manual clock setting
  • dynpm for ondemand clock setting. But it just change between mid and high. Never going to low. At least to me.

If you select profilepm, select clock manually.

  • low
  • mid
  • high
  • auto

I never tried auto. But sounds like good for laptop.

Quote from X.org radeon wiki article,

"auto" selects between "mid" and "high" power states based on the whether the system is on battery power or not. The "low" power state are selected when the monitors are in the dpms off state.

Use 'gpu' command show current method and clock.

All about these settings are from here,

KMS Power Management Options

I used to 'low' in 11.10 but little bit sluggish when many firefox tabs and windows open. After jump to 12.04, I'm using unity and 'fglrx-updates' driver. It works quite well.

If you good with these settings, save them for reboot.

Install sysfsutils package then add rule to /etc/sysfs.conf file.

class/drm/card0/device/power_method = (profile or dynpm)
class/drm/card0/device/power_profile = (select between auto, low, mid, high if u choose 'profile' method)

You can remove second line If u select 'dynpm'

If power management is your concern, then I suggest you switch to latest AMD Catalyst 12.2 which does a far better job of PM and suspend.

Before installing (or reinstalling) any AMD/ATI fglrx Catalyst Propietary Driver, you need to purge any configuration to make fglrx a clean space to work with X.Org, this is because drivers may get bugs on your computer such as slowness, inadecuate functionality, or multiple issues. Also, in order to try out this method, I suggest you to remove the scripts you made to underclock your computer from the page you said on the question. If you have any doubts about his procedure don't forget to ask.

To remove the fglrx, run these commands;

sudo sh /usr/share/ati/fglrx-uninstall.sh
sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev* xorg-driver-fglrx

(Please note, if first command gives errors, just skip to second command)

If in case you haven't made the download from the ATI website, get the lastest with these commands (the fglrx from Ubuntu repositories or "Additional Drivers(Jockey)" are outdated);

To make a folder for the download and work in your home folder, although not necessarily;

cd ~/; mkdir catalyst12.2; cd catalyst12.2/

To download the lastest driver, (which as time of writing is Catalyst 12.2);

wget -O amd-driver-installer-12-2-x86.x86_64.run http://www2.ati.com/drivers/linux/amd-driver-installer-12-2-x86.x86_64.run

(Note that download will work for both 32 bit and 64 bit architectures)

Make the installer script executable;

sudo chmod +x amd-driver-installer-12-2-x86.x86_64.run

Run the installer script;

sudo sh ./amd-driver-installer-12-2-x86.x86_64.run

Now follow install with defaults, when setup is finished, open a new terminal and type;

sudo aticonfig --initial -f

When finished, make sure to reboot/restart your computer. Don't try any application before rebooting, as you may unstabilize your X.Org, so just reboot in the same terminal with;

sudo reboot now

Or do it within your graphic interface.

Make sure to tell us how it went through, good luck! ;)

I found the sysfsutils-solution not to work for me (as described here). For others with the same problem this might be an alternative solution using pm-utils. I'm not sure if it is the best way to do it (I'm new to Linux) but it does all I wished for: Set the radeon power_profile to low on boot and retain that setting after suspend-resume.

Step 1: Create hook

gksudo gedit /usr/lib/pm-utils/power.d/radeon-power_profile

Step 2: Fill in the desired setting

#!/bin/sh

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

exit 0

Step 3: Make it executable

sudo chmod +x /usr/lib/pm-utils/power.d/radeon-power_profile

That's it :)

There is new improvment :)

Resolves stability issues found in the previous AMD Catalyst 12.11 Beta8 driver for Linux For users experiencing issues with HDMI Audio under Ubuntu 12.04, users should try installing the “dkms-hda - 0.201211291615~precise1” package from https://code.launchpad.net/~ubuntu-audio-dev/+archive/alsa-daily/+packages and reboot; this will resolve the HDMI Audio issue found in Ubuntu 12.04

http://support.amd.com/us/kbarticles/Pages/AMDCatalyst1211betadriver.aspx

But wait there is more they have made a new version in 2013

AMD Catalyst™ Proprietary Display Driver - Linux x86 & Linux x86_64

Stable version Amazing

Description: Automated installer and Display Drivers for Xorg/Xserver 6.9 and above (up to 1.13)

Add radeon.dpm=1 to your kernel boot parameters.

It makes all the difference for hd2xxx.

To do this, edit the file /etc/default/grub, for example

sudo nano /etc/default/grub

find the line that begins

GRUB_CMDLINE_LINUX_DEFAULT=

and between the quotes, add radeon.dpm=1 to the parameters that are already there, so that after your edit, the line looks something like

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.dpm=1"

save, exit, then run

sudo update-grub
