Linux Mint and blinking/flashing/blanking screen
August 15th, 2016
I suppose this problem will affect many people, so here’s one answer for Google to find. The latest Mint (18) has some graphics problems on at least the integrated GPU of Broadwell chips — others have reported similar issues on Skylake chips as well. It is reasonable to assume that other Ubuntu derivatives are susceptible too. It seems that kernel 4.4 introduced some bug that causes the screen to occasionally turn black for a fraction of a second. Changing the window manager or compositor do not alleviate the problem.
Mint 17.x does not suffer from blinking as it uses 3.x kernels. Updating to 4.6.3 seems to solve the issue as well, so it’s probably not a question of the X server either. The only quirk is that Mint doesn’t let you use other kernels than the 4.4 series easily. Here’s one package with instructions that did the trick, use at your own risk.

Hi, there is also a quickfix to stop the wifi lamp to blink.
Put this text
options iwlwifi led_mode=1
in the following file (possibly you have to create the file):
Linux Mint (Debian) or Ubuntu: /etc/modprobe.d/wlan.conf
Arch Linux: /etc/modprobe.d/modprobe.conf
Now restart your system or reload the WiFi driver using:
sudo -i
modprobe -r iwlwifi && modprobe iwlwif
I was looking for MSX related stuff and found this article, and i just had the same problem on my hp laptop.
