Screen flickering on devices with Intel graphics

A possible cause can be buggy Intel graphics power management. You can try disabling it by adding i915.enable_rc6=0 boot flag.

To do this from a running system and make it permanent, run the following terminal command:

  1. EDITOR=gedit sudo /etc/default/grub

File /etc/default/grub will be opened in gedit with administrator privileges (so be careful with the next step).

  1. Find the GRUB_CMDLINE_LINUX line
  1. Change it to look like this:
  1. Save the file.

Restart for this to take effect.

NOTE: Instead of gedit you can use a text editor of your choice.
