Bug 94430

N.B. to avoid miscommunication, when I mention "suspend" I'm only talking about the monitor. The laptop is on and all programs are running -- but screensaver locks the screen & Display Power Management is set to Standby/Suspend/Off

Are both displays mentioned in the bug connected to the Intel device?

Can you please boot with drm.debug=0xe, reproduce the bug, then attach the dmesg output here?

If this is a regression, is it possible for you to use git bisect in order to discover which one is the bad commit? I know this takes some time, but it's usually a very efficient way of finding the problem.

dmesg

I'm not 100% sure about the topology of the hardware, but I'm quite sure that nvidia driver isn't loaded and the LED indicator (one that lights up while nvidia card is being used) is off.

dmesg is attached
* booted up, logged in
* started up a few apps/windows
* locked the screen
* waited for one monitor's LED to change to powersave/etc. mode
* unlocked, saw XFCE's "configure displays" dialog, windows on the wrong monitor
* dumped dmesg


Bisecting the kernel would be very inconvenient.. I have a plain Fedora install (pre-packaged RPMs) and it's a work laptop.
I'll see what I can do with Koji kernel builds

Just found a much easier way to replicate the issue (or maybe it's a closely related issue): just power off the "primary" monitor.

More info:

XFCE's display config lists my displays as:
- 1. AU Optronics 15"
- 2. Viewsonic Corporation 27"
- 3. AOC Intl 23"

eDP1 is the laptop display, not used;
HDMI2 uses the actual HDMI port, primary display;
HDMI3 uses the DisplayPort connector, secondary display (uses DP->DVI adapter, so maybe that's why it's detected as "HDMI"?)


When I power off the secondary display, nothing happens to the desktop (as expected)

When I power off the primary display, some windows are switched over to the primary display's region

Apparently, xfce4-terminal and pidgin windows are not affected for some reason; Firefox and Thunderbird definitely are

Hope this helps!

*ping*
anything happening here?

Could you try the drm-intel-nightly branch from
git://anongit.freedesktop.org/drm-intel

It has a fix for the HDMI live status check problem mentioned in comment 4.

Timeout, assuming that this is fixed by now based on the comment 8. Please retest with the latest drm-tip and reopen if problem still persist in your system.
