Subject: 4.8-rc1: it is now common that machine needs re-run of xrandr after
 resume

Hi!

I have

00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset
Integrated Graphics Controller (rev 03)

In previous kernels, resume worked ok. With 4.8-rc1, I quite often (1
in 10 resumes?) get in state where primary monitor (DVI) is dead (in
powersave) and all windows move to secondary monitor (VGA). Running
"xrandr" fixes that.

I'll update to newer rc and see if it happens again, but if you have
any ideas, now would be good time.

Best regards,
									Pavel
