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

I have seen this in 4.8 up to rc5 as well. I am not sure yet about rc6 which I 
am currently running.

I didn´t run xrandr by hand. But I ran systemsettings, dragged the second, 
deactivated external display back beneath the internal laptop display, 
activated it again and applied this changes. I think this has a somewhat 
similar effect as Plasma uses RANDR as well.

Ok, it happened again today, with yesterdays version of 4.8-rc6. I'm
glad I'm not the only one.

Intel folks, any ideas? Can you reproduce it?

It's possible (but not confirmed yet) we've seen this in our CI, but has
slipped through because it's sporadic.

BR,
Jani.

Ok. With -rc6, X are completely broken. I got notification "could not
restore CRTC config for screen 63" or something like that, and window
manager just does not start.

X log is attached as delme, kernel log as delme2. Nothing too
suspicious :-(.

Ugh. Can you bisect from v4.7, assuming it worked? That's probably the
fastest way to resolve this.

Also, if you don't mind, please file a bug at [1], attaching the logs
there. It'll be easier for me to direct attention and priority to the

Also, if you don't mind, please file a bug at [1], attaching the logs
there. It'll be easier for me to direct attention and priority to the
bug, which will help you too in the end.

The "completely broken" part -- something broke in my userland, as
booting to the old kernel does not fix it. I'll have to figure it out.

For the "sometimes need xrandr after resume": I don't think I can
bisect that. It only happens sometimes :-(. But there's something
helpful in the logs:

Pavel, Martin, do you always see this when the display fails to resume?
Is it HDMI/DVI for both of you?

Subject: [PATCH] Revert "drm/i915: Check live status before reading edid"
Organization: Intel Finland Oy - BIC 0357606-4 - Westendinkatu 7, 02160 Espoo
Cc: Jani Nikula <jani.nikula@intel.com>

This reverts commit 237ed86c693d8a8e4db476976aeb30df4deac74b.

Our current implementation of live status check (repeat 9 times
with 10ms delays between each attempt as a workaround for
buggy displays) imposes a rather serious penalty, time wise,
on intel_hdmi_detect().  Since we we already skip live status
checks on platforms before gen 7, and since we seem to have
coped quite well before the live status check was introduced
for newer platforms too, the previous behaviour is probably
preferable, at least unless someone can point to a use-case
that the live status check improves (apart from "Bspec says so".)

Subject: [PATCH] Revert "drm/i915: Check live status before reading edid"
Organization: Intel Finland Oy - BIC 0357606-4 - Westendinkatu 7, 02160 Espoo
Cc: Jani Nikula <jani.nikula@intel.com>

This reverts commit 237ed86c693d8a8e4db476976aeb30df4deac74b.

Our current implementation of live status check (repeat 9 times
with 10ms delays between each attempt as a workaround for
buggy displays) imposes a rather serious penalty, time wise,
on intel_hdmi_detect().  Since we we already skip live status
checks on platforms before gen 7, and since we seem to have
coped quite well before the live status check was introduced
for newer platforms too, the previous behaviour is probably
preferable, at least unless someone can point to a use-case
that the live status check improves (apart from "Bspec says so".)

Was busy up to now, and weekend also quite full already.

Thing is: I didn´t see this blank screen thing with 4.8-rc6 so far. And I did 
not have above EDID stuff in my log either. So I first wait whether I see 
blank screen again and if so, then know that a test would make sense. Maybe I 
see it before I complete a rc7 or rc8 (if there will be one), then I would 
include the patch of course.

Sorry, spam filter hidden your emails.

I believe I still see the issue on v4.9-rc1. ... does it still make
sense to retry the patch?

What I also is re-aranged windows. So I get resume, I get both
monitors, but I also see that X windows lost connection with the big
monitor (and re-arranged my windows for me).

Oh and I guess I should mention:

1) Yes, I only see the issue on the DVI output. VGA seems to work.

2) I do have power switch on the monitors, so it is possible that
during resume, monitors have no AC power. (Not merely turned off by
the soft switch. No AC power.)

Thanks,
									Pavel

According to zgrep "EDID" /var/log/kern* I don´t have any EDID related error 
messages. I am using DisplayPort cable via ThinkPad Minidock Plus (dock for 
ThinkPad T520) or what it was named.

According to zgrep "EDID" /var/log/kern* I don´t have any EDID related error 
messages. I am using DisplayPort cable via ThinkPad Minidock Plus (dock for 
ThinkPad T520) or what it was named.

[   234.547] (EE) intel(0): failed to set mode: Permission denied
upon resume.

There is a VT switch so there should be a DropMaster, SetMaster combo
across resume, but that didn't flag any errors. I couldn't see any sign
of logind (so no revocation), so just some breakage in the setmaster
reauthentication?
