Fan making too much noise on Ubuntu? Let’s fix it
ubuntu
I’ve a Sony Vaio SB series, the one with double graphic cards. I just noticed that on Windows everything was smooth but on Linux the fan was running at maximum speed all the time and the laptop was very hot.
After some investigations I understood that this behavior was due to the second graphic card which was on meanwhile the integrated graphic card was working. After a bit of googling i found a nice explanation of my problem reading this page on the ubuntu help.

If you have the same problem just put this line:
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
just before the exit 0 command. This will shutdown the second graphic card as soon as the computer boots, increasing battery life and decreasing fun speed, and thus, noise.

Hi, I’ve got the same laptop as yours….and even though the article is quite old I give it a try.
Where exactly is the “exit 0 command”? Thanks
It does not matter. I found it. It’s in /etc/rc.local.
It works 😉
yeah 😉 you found it.
I was having the same problem but didn’t even realize it could be fixed. i’ll try this at home and let you know. btw my laptop is a vaio VPC-SE series
