    Ubuntu makes my laptop to overheat

    Hi all,im new in this forum,in fact i just made a registration.I have read many useful threads from this forum,but i could not find a salution to my current problem.
    I would like to apologise in advance in my thread is in wrong category.
    Here is the problem.I bought IBM thinkpad T60P,i know it is a old laptop but it works perfect for me.I have been using ubuntu for 3 years now.I installed ubuntu 12.04 LTS,and some softwere that i use.I could not find fglrx driver which is compatible with this version of Ubuntu and my vidio card (Ati FireGL v5250),so i decided to use open source driver.When i try to watch HD video in YouTube it loads my processor (T7600) to 100%,also it does not play vary smooth.I forgot to mantion that i use Windows XP alongside with Ubuntu.In Win i use some old driver for video card provided by Lenovo web site.When i use Ubuntu for small tasks like listening to music or little programming,i can't even keep the laptop in my lap it is so hot.I installed lm-sensors temperatures are too high,it says that GPU temp is about 77-99 C.The processor temp is about 60C.When im using Win XP i can feel that laptop is a lot colder,my fan is running at the same speed.That is the explanation of my problem,if i have missed something you can ask me.
    I forgot to mantion that im using CPU in on_demand mode.

    THANKS

    Some process might be using up all of your cpu.
    OPen terminal and type :
    Code:
    top
    The output of this will be the top consumers of your cpu.
    Identify the processes and kill them if unneeded
    Code:
    pkill -P (process ID)

    Compiz shoudnt be using 8%.
    Normally it uses just 1-2%

    Okay steps you can try :
    1) Update BIOS
    2) If possible clean up ur lappy. (Better to clean it)
    3) Update graphic card drivers. (Install fglrx drivers)

    Overheating is mostly caused by a fed up fan. Clean your laptop's fan if you haven't done so.

    Re: Ubuntu makes my laptop to overheat

    Here is a snapshot with temperatures under Windows XP.It is considerably colder.As i mentioned i could not find fglrx which works with my card under Ubuntu 12.04.I think that previous owner has cleaned it.It is not make sense to overheat under Ubuntu,and to be OK with WinXP and problem to be fed up fan.

    Basically its the GPU that is hotter in Ubuntu.
    It is the problem with your graphic card drivers for ubuntu.
    They are obsolete because ATI didnt update your drivers nor made efforts to optimize ur card's usage in ubuntu.

    So "Blame it on ATI"

    Re: Ubuntu makes my laptop to overheat

    When i tried to install fglrx it said that my version of ubuntu is not supported,or something similar.What would happen if i update my bios i dont see a point.WinXp is also using some old catalyst provided by lenovo web site 8.593.100.7-090929a-090748C-Lenovo.
    Is there way to install older fglrx which support my card(which version?) to Ubuntu 12.04 ?
    During the CPU stress test in Everest 5.50 i noticed that GPU is getting higher as well.

    I'm sure the less than perfect driver is contributing to this, but I'd bet if you were to switch to a lighter desktop environment you would find the system very usable.

    Even if the drivers are OK, all the 3D processing in compitz is probably too much for your older hardware to do comfortably. XP doesn't have this issue.

    I have an old dell optiplex that I run xfce on and it purrs! When I try to run Unity or Cinnamon or anything that uses compitz by default, I get similar heat issues, even though it appears to run fine.

    Just like living within your means, you should compute within your hardware's comfort zone. Just because it can run compitz, doesn't mean it should.

    Good for you! Get tired of this knee-jerk "update your BIOS" response to overheating problems. Clearly, if the PC is NOT overheating in MS Windows, it is NOT a BIOS problem.

    WinXp is also using some old catalyst provided by lenovo web site 8.593.100.7-090929a-090748C-Lenovo.

    Unfortunately, no. Restricted driver support for your card ended when the X-server upgraded to a new one that would no loger work with the ATI drivers. I had an ATI X1650 at the time and had to switch to using the open-source Radeon drivers. AMD did the same thing again this summer when they dropped support for the HD 2x/3x/4x line starting with Ubuntu 12.10.

    Will not respond to PM requests for support -- use the forums.
