Laptop temperature gets really high [SOLVED]

[lindaonline15]

hi,

When I am using kubuntu, my laptop's temperature increases so so much. the fans are working really hard and still I can feel the heat. This is while when I used windows previously the laptop worked perfectly normal during operations.
any suggestions?

p.s: this has nothing to do with Oneiric distro since I had the same problem using natty, bus since I upgraded to this distro, figured I should discuss here.

Re: Laptop temperature gets really high

Do you have an amd/ati graphic card? Opensource ati driver doesn't have good power management.

So if you have ati card, install proprietary driver from additional drivers and your card should be much cooler.

under additional drivers i got two choices...
both same name, but one is a (post-release update).
which is better to do install?

Usually you can pin down this behaviour to one single process or application.
Press CTRL + ESC and see in the CPU% column what is causing this.

highest % is the Xorg...

yes... I have the same issue...
then I just leave it with the main one.
thx

Re: Laptop temperature gets really high

Don't use post release one. It is broken.

Re: Laptop temperature gets really high [SOLVED]

I did install the proprietary drivers... its been sometime, but my laptop still gets very hot!!
how to solve it...
my fan is heavily working and still its really hot...

Re: Laptop temperature gets really high

Have you tried using another screen resolution, and/or switching from opengl to xrender? Disabling desktop effects?

[lindaonline15]

Re: Laptop temperature gets really high

Have you tried .... opengl to xrender? ...

this part should be good.
however, would you guide me in doing it coz my settings are default so i assume is opengl.
I tried to look it up myself to do it but couldnt get accurate results and since it seems any tiny wrong configuration will crash the whole thing up, i was afraid of giving it a try...
i read this post: http://kubuntuforums.net/forums/inde...opic=3099721.0 but the post is old, and i dont think the kde is the same version as when that post was posted. mine is 4.7.2 based on what 'kate -v' reports...

Re: Laptop temperature gets really high

KMenu --> Settings --> System Settings --> Desktop Effects --> Advanced tab --> Composite type.
Chose XRender
Click "Apply".
A dialog will appear giving you 30 seconds to "Accept" the new setting or it will revert. Click "Accept..."

Re: Laptop temperature gets really high

All done.
No difference.
the best part is that there is no difference in how hot it gets in both when I was using openGL (with many desktop effects) and xrender (with no desktop effects)

Re: Laptop temperature gets really high

I don't have an ati card, so I don't know the specifics of playing with them. But there are a couple of experiments you might try.

1. Get out of X to a terminal console. One way of doing this is to log out, then at the greeter screen choose Menu > console login. When you get into the console,

sudo service kdm stop

This will stop X, and in a few minutes your laptop should start to cool down.

2. Move your /etc/X11/xorg.conf out of the way. You can do this with:

sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.saveme

Then try restarting X with:

sudo service kdm start

Now this is the part about the ati drivers I don't know about --whether it will start without an xorg.conf or not. Real quick to find out, though. If it doesn't, you could try running from the console:

sudo dpkg-reconfigure -phigh xserver-xorg

and then restarting X.

If that doesn't do anything, you will need to move that xorg.conf.saveme back to xorg.conf.

These are just experiments to try, in the off chance that it's a bad X startup file, or else a bad xorg.conf that's giving you the trouble.

You might also want to have a look at /var/log/Xorg.0.log (that's a "zero" between the dots) and see if anything jumps out as an error message. It might really be starting more than one instance of X, which linux can certainly do, but your graphics chip might not appreciate.

PS: I am also wondering if kdm is actually running, or maybe gdm or lightdm instead of, or along with it. Either of those scenarios could heat your graphics up quick. Try, from inside kde, running konsole and:

ps aux | grep lightdm

and

ps aux | grep gdm

If you have things like xfce installed, you might also want to look for their dm's, not sure what they are called.

If either one of those things are running, then

sudo dpkg-reconfigure kdm

and choose kdm from the menu that comes up, then reboot. That will clear the rogue dm away.

Re: Laptop temperature gets really high

thx alot dr. druid for helping me out as usual but unfortunately i couldn't get any results.. i tell you why:

I don't have an ati card, so I don't know the specifics of playing with them. But there are a couple of experiments you might try.

1. Get out of X to a terminal console. One way of doing this is to log out, then at the greeter screen choose Menu > console login. When you get into the console,

sudo service kdm stop

This will stop X, and in a few minutes your laptop should start to cool down.

i didnt notice any cooling down here...

2. Move your /etc/X11/xorg.conf out of the way. You can do this with:

sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.saveme

Then try restarting X with:

sudo service kdm start

Now this is the part about the ati drivers I don't know about --whether it will start without an xorg.conf or not. Real quick to find out, though. If it doesn't, you could try running from the console:

sudo dpkg-reconfigure -phigh xserver-xorg

here I got "xserver not installed" !!

and then restarting X.

If that doesn't do anything, you will need to move that xorg.conf.saveme back to xorg.conf.

yup, that didnt do anything...

These are just experiments to try, in the off chance that it's a bad X startup file, or else a bad xorg.conf that's giving you the trouble.

You might also want to have a look at /var/log/Xorg.0.log (that's a "zero" between the dots) and see if anything jumps out as an error message. It might really be starting more than one instance of X, which linux can certainly do, but your graphics chip might not appreciate.

ok, im not really sure what kind of message i should look for in here...

PS: I am also wondering if kdm is actually running, or maybe gdm or lightdm instead of, or along with it. Either of those scenarios could heat your graphics up quick. Try, from inside kde, running konsole and:

ps aux | grep lightdm

and

ps aux | grep gdm

here I got these for the above:

$ ps aux | grep lightdm
linda   5396 0.0 0.0 12000  900 pts/1  S+  22:46  0:00 grep --color=auto lightdm
$ ps aux | grep gdm
linda   5398 0.0 0.0 12000  900 pts/1  S+  22:46  0:00 grep --color=auto gdm

If you have things like xfce installed, you might also want to look for their dm's, not sure what they are called.

If either one of those things are running, then

sudo dpkg-reconfigure kdm

and I got nothing here...

and choose kdm from the menu that comes up, then reboot. That will clear the rogue dm away.

what else do you suggest me..?

Re: Laptop temperature gets really high

On an HP laptop with an ATI card, I had to use the ATI powerstate (??) command to change from the default highest performance state to the lowest state. I had to write a script to do this and put it in autostart, or manually run the script within 1 minute of logging in. Otherwise the laptop would get so hot it would shut itself down.

Re: Laptop temperature gets really high

here I got "xserver not installed" !!

That certainly does not look right.

What i would do:

sudo apt-get install --reinstall kubuntu-desktop

then
sudo dpkg-reconfigure kdm
and set kdm as the default manager.

Then reboot.
