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.
First select default method.
If you select profilepm, select clock manually.
I never tried auto. But sounds like good for laptop.
Quote from X.org radeon wiki article,
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.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;
(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;
To download the lastest driver, (which as time of writing is Catalyst 12.2);
(Note that download will work for both 32 bit and 64 bit architectures)
Make the installer script executable;
Run the installer script;
Now follow install with defaults, when setup is finished, open a new terminal and type;
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;
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 radeonpower_profile
tolow
on boot and retain that setting after suspend-resume.Step 1: Create hook
Step 2: Fill in the desired setting
Step 3: Make it executable
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

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 examplefind the line that begins
and between the quotes, add
radeon.dpm=1
to the parameters that are already there, so that after your edit, the line looks something likesave, exit, then run
