I am having issues with the Ubuntu 16.04.
- Dell XPS L502
- i7-2630QM Quad Core
- Linux 4.4.0-36-generic
- Nvidia GT540M (have the proprietary driver installed 361.42, and bumblebee)
The CPU core temperature is always over +76.0°C and the fan is always ON. The GT540M is also at 75+ temperature.
I have installed TLP, Intel Powertop, and have the Laptop optimized the for powersave mode.
Sometimes when I restart, the laptop cools down and I do not have any issue until the next restart. I have gone days without restarting. But this is seriously bugging now. Sometimes even simple videos on VLC start the fan, and then it will not turn off until I restart an arbitrary number of times.
Is there any other solution I should try?
Edit: Solved. Turns out you do not need tlp/powertop/etc. (although you might use them for even more optimized performance).
The only thing you need to do is install nvidia drivers (easiest way from additional drivers). Then open up the Nvidia X Server Settings (from dash) and change the PRIME profile to Intel (power saving mode).
Haven't had any issues since changing that setting (around a month).
