Current using kernel 4.4.3-300.fc23.x86_64, git intel driver (commit d1672806a5222f00dcc2eb24ccddd03f727f71bc) My laptop is connected to 2 external monitors. Soon after screen is locked (xscreensaver), the monitors go into suspend mode. As of 4.4.x kernel updates, this causes window manager (xfwm4-4.12.3-2.fc23.x86_64) to detect one of the monitors as "disconnected" and all windows are moved to the primary monitor. When unlocked, both monitors are displaying everything, but windows had been moved already and don't snap back to the 2nd monitor. Also tried on 4.4.2-301.fc23.x86_64 Issue was not present on 4.3.x and earlier kernels (same setup, booted to 4.3.5-300.fc23.x86_64 does not have the problem) Note, probably irrelevant, but video hardware is dual: 00:02.0 VGA compatible controller [0300]: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller [8086:0416] (rev 06) (prog-if 00 [VGA controller]) Subsystem: CLEVO/KAPOK Computer Device [1558:5281] Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0 Interrupt: pin A routed to IRQ 35 Region 0: Memory at f7400000 (64-bit, non-prefetchable) [size=4M] Region 2: Memory at d0000000 (64-bit, prefetchable) [size=256M] Region 4: I/O ports at f000 [size=64] Expansion ROM at <unassigned> [disabled] Capabilities: [90] MSI: Enable+ Count=1/1 Maskable- 64bit- Address: fee00018 Data: 0000 Capabilities: [d0] Power Management version 2 Flags: PMEClk- DSI+ D1- D2- AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=0 PME- Capabilities: [a4] PCI Advanced Features AFCap: TP+ FLR+ AFCtrl: FLR- AFStatus: TP- Kernel driver in use: i915 Kernel modules: i915 01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GK104M [GeForce GTX 870M] [10de:1199] (rev ff) (prog-if ff) !!!

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.
Created attachment 122170 [details] 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" This corresponds to xrandr's eDP1, HDMI2, HDMI3: $ xrandr Screen 0: minimum 8 x 8, current 3840 x 1080, maximum 32767 x 32767 eDP1 connected primary (normal left inverted right x axis y axis) 1920x1080 60.00 + 40.00 1400x1050 59.98 1600x900 60.00 1280x1024 60.02 1280x960 60.00 1368x768 60.00 1280x720 60.00 1024x768 60.00 1024x576 60.00 960x540 60.00 800x600 60.32 56.25 864x486 60.00 640x480 59.94 720x405 60.00 640x360 60.00 DP1 disconnected (normal left inverted right x axis y axis) DP2 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) HDMI2 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 598mm x 336mm 1920x1080 60.00*+ 50.00 59.94 1920x1080i 60.00 50.00 59.94 1600x1200 60.00 1680x1050 59.88 1400x1050 59.95 1280x1024 75.02 60.02 1440x900 59.90 1280x960 60.00 1152x864 75.00 1280x720 60.00 50.00 59.94 1440x576 50.00 1024x768 75.08 70.07 60.00 1440x480 60.00 59.94 832x624 74.55 800x600 72.19 75.00 60.32 56.25 720x576 50.00 720x576i 50.00 720x480 60.00 59.94 720x480i 60.00 59.94 640x480 75.00 72.81 66.67 60.00 59.94 720x400 70.08 HDMI3 connected 1920x1080+1920+0 (normal left inverted right x axis y axis) 521mm x 293mm 1920x1080 60.00*+ 1680x1050 59.88 1280x1024 75.02 60.02 1440x900 59.90 1280x960 60.00 1280x720 60.00 1024x768 75.08 70.07 60.00 832x624 74.55 800x600 72.19 75.00 60.32 56.25 640x480 75.00 72.81 66.67 60.00 720x400 70.08 VGA1 disconnected (normal left inverted right x axis y axis) VIRTUAL1 disconnected (normal left inverted right x axis y axis) 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

*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.
