I have been using elementary OS, for quiet along time. Its based of Ubuntu, and once I got sick of no customization options, I went for Ubuntu 12.04 LTS. Now this overheats my laptop constantly, it takes some time but it get so hot I can smell it and then (luckly) shuts down.

Why is this happening? when Eos was so stable?

(laptop: acer aspire 7741g, intel i5, radeon hd5650)

I solved this problem on my Avell notebook uninstaling the actual kernel and instaling a 3.2.x-xx kernel. There are other kernel versions that also do not have this bug.

You can do it using a tool like Synaptic Install synaptic.

  1. Check the actual version of your kernel with the command

    uname -r

    in a terminal.

  2. Then mark the kernel files for complete removal in Synaptic, and mark the desired kernel to install.

  3. After removing the trouble kernel and installing the good kernel, open a terminal and run:

    sudo update-grub

  4. Reboot.

This worked for me.

This problem is because some kernel releases does not handle the thermal control of the CPU appropriately.

Thats because of kernel (linux) the best way to get red of overheating or at least reduce it is upgrading your ubuntu to 12.10 or compile a higher version of linux (kernel) like 3.4

This is over simplifying, there is no guarantee that 12.10 will be better, neither for a "higher" kernel. – guntbert Mar 20 '13 at 20:21
    
I said the best way not the way. yeah you are right there is no guaranty. – MostafaJF Mar 20 '13 at 20:58

Best guess is that the 3D desktop goodness is giving that AMD video a run for its money (Or there are bad/no 3D drivers). If it's reasonable, I'd try either a simpler window manager, or try to install first party video drivers.
