Nvidia Optimus, Clevo, and power management

21 Aug 2019

I've had a PC Specialist Optimus IX (Clevo N850EP6) laptop for a while, dual booting Debian testing (with kernel 4.19) and Windows 10. This laptop has a hybrid graphics system with an integrated Intel UHD 630 and a dedicated NVIDIA GTX 1060 and, while it works pretty well for the most part, there have been several issues regarding power management, freezes (looking at you lspci!) and other malfunctions.

"Luckily" I am not the only one who has had these issues, so I finally could find a good solution for my case.

Bumblebee and kernel updates

21 Nov 2013

Just recently, my Debian machine updated the kernel to 3.11. I should note that I have an Optimus laptop, which means that I need Bumblebee to enable/disable the discrete graphics card and have power management.

This is more of a reminder to myself than anything, but don't forget that linux-headers must be installed in order to build the DKMS modules for the kernel, including the bbswitch module (used for power management) as well as the nvidia module itself (otherwise Bumblebee will not be able to load the driver). Installing the headers is as easy as doing:

# apt-get install linux-headers-`uname -r`

There's that.
