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).

2. Find the GRUB_CMDLINE_LINUX line

3. Change it to look like this:

GRUB_CMDLINE_LINUX="i915.enable_rc6=0"

4. Save the file.

Restart for this to take effect.
