Display turns off after app restart (Intel NUC, 2.2.0, F25)

Product support

Hello,

we are experiencing a curious issue with app reboots. We are running an app that uses Xorg and Intel NUC.

  • When the device is cold booted or rebooted, the app starts correctly and display works.
  • When the app is restarted (for example from the resin.io dashboard) the app seems to start ok (Xorg.0.log is identical to the cold boot one) but the display goes directly to power saving mode (so there is no display input at all) and doesn’t recover.

I think that the problem started to appear when we upgraded to Resin 2.2.0 + Fedora 25 based container. You can find the Xorg.0.log attached.

Any ideas?

So the attached log file is after the cold boot where the display receives signal.

Maybe @floion or @agherzan have some ideas here…

You can also control the display power management signaling from your container.

Best,

Yes, the Xorg logs are identical (cold boot and app reboot).

I’ll try to disable DPMS if it makes any difference.

DPMS disabled => Issue persists.

Hi, how do you disable DPMS?
Also, do you recall in what combination of resinOS and base image this used to work?

12

Hi,

“xset s off -dpms” in container after X start.

ResinOS 2.0.6 and F24, as far as I can remember.

13

Thanks. Can you try to run on 2.2.0 using the F24 base image?

14

Yeah, I’m in progress of downgrading some packages and get back to you with results asap.

15

Alas, same thing with F24.

Curiously enough, I was able to circumvent the issue by placing a 5 second sleep followed by “DISPLAY:0 xrandr --output HDMI1 --auto” into app startup script (which is run with startx).

Without the startup hack xrandr reports the following:

Hm. If you get the same result on F24 then it’s really strange. There’s no recent change I can think of in the hostOS that may cause this.
Do you happen to have multiple graphical apps where you can see this behavior exhibiting? Or so far you have only experienced with this one app?
