I recently installed Ubuntu 16.04 on a new partition to dual boot with Windows 10.

I have a Dell XPS 15 (i7 7th Gen). I constantly get screen freezes at random intervals. I have seen the c-state bug and have added the necessary extension to grub to avoid this.

I do not know how to proceed from here.

Any help is appreciated.
