    Exclamation Laptop overheating until crash on Ubuntu 13.04

    I installed Ubuntu 13.04 on my Vaio-Laptop a few weeks ago, and recently the overheating has become more and more of a problem. After half an hour it crosses 80°C, and a few minutes later the Laptop crashes and needs to cooldown before it can start again. While it is on the fan is running constantly.
    I haven't found a solution by myself, so i'd appreciate your help

    PC Model: Vaio VPCEB3E1E/WI
    Graphics card:
    ATI Mobility Radeon HD 5470
    Mobility Radeon HD 5000 Series
    CPU: Intel® Pentium(R) CPU P6100 @ 2.00GHz × 2
    Dual Core
    64-bit
    RAM: 4GB; 8GB maximum
    Chipset:
    Mobile Intel HM55 Express
    As far as I can tell it isn't an APU. Hybrid, not so sure.
    Here are some more specs, should you want them

    Hello!

    Can you give us a little bit of information about your hardware, particularly the CPU and graphics?

    Ah, yes. Sorry, I forgot that ^^
    As far as I know there are some problems with the Mobility Radeon card drivers which cause the system to increase the temperature by 25°, but I don't really know how to fix that :/

    That is common.

    Again, though, we need some detailed information about your hardware.

    What series of ATi GPU? Is this an APU? Is this an Intel/ATi hybrid graphics arrangement?

    Thanks!

    I added a link to the Laptop's webpage. You should be able to find everything there

    OK

    Have you installed the proprietary fglrx driver?

    Yes, but apparently it doesn't support my hardware.

    That GPU should be supported, although sometimes the M GPUs are actually just overclocked versions of earlier chips. You might find that in ATi's odd naming scheme, a 5470M is really an HD 4000 unit that is overclocked.

    If you have the driver installed, could you please post the results of

    Code:
    fglrxinfo

    The 5470 is not a rebadge and should be supported by fglrx/Catalyst:

    Some of the M GPUs in the HD 5000 series are (some of them up through 5300), but in this case the chip is a Cedar so it is a real live HD 5000.
