--- Comment #44 from ExecutorElassus <n.andrew.walsh at gmail.com> ---
I have a new-ish MSI laptop. With no kernel option set (I'm using a gentoo
4.6.3 kernel atm), the screen flickers rapidly, unless the mouse is moving (in
which case the screen is steady). If I set i915.enable_psr=0 in the kernel
options at boot, the screen does not flicker, but it also does not update *at
all* unless I move the mouse. That is:

1) type some commands and hit enter → nothing changes on screen
2) move the mouse → the screen updates, showing that the commands have run and
showing output.

Both of these states (ie, flickers, or no flicker but also no refresh, unless
the mouse is moving) render my laptop more or less unusable. What are the other
possible ways to fix this? Does danvert's patch resolve the issue?
