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.
sysfsutilspackage then add rule to
You can remove second line If u select 'dynpm'
