I have dell inspiron q17r with two graphic cards and I noticed that it is overheating. I installed bumblebee, jupiter and flashblock, I followed this but it still got to even 74C. Here I found something:

Power management relies on ACPI, disabling ACPI renders bbswitch unusable. Be sure that your kernel boot parameters do not contain on of the options noacpi, pci=noacpi, acpi=off.

And I changed it to pci=noacpi because without it didn't even started.. I followed this but in point 4. I installed bumblebee instead.

What should I do?

Have you considered getting a cooling pad for your laptop? My brother's laptop has the same problem, but a cooling pad does a good job of preventing overheating.

    yeah I got it but it's ridiculous solution, don't You think? It should work correctly without cooling pad.. @Qasim - it's not very helpfull to my problem. – mati Jun 28 '13 at 15:28
  • As someone here said: http://askubuntu.com/questions/74246/can-i-mess-up-my-hardware-with-acpi-off-or-acpi-noirq it's not very healthy to run on such high level. If I could get my ubuntu to work without acpi=noacpi it would be great. So..anyone knows any solution to that? :P – mati Jun 28 '13 at 15:44

Try changing pci=noacpi to pci=acpi- basically it should enable ACPI. (src: from edit on your post:)

EDIT: So I changed pci=noacpi to pci=acpi and.. it's working great :) don't know what are the consequences but the temperature is lower than on windows :)

I think this was simply a case you misread this :)
