Screens do not stay off when blanking

[Enigma]

After some idle period (5-15 minutes) the screens are supposed to blank and power off.

They appear to do this once but then come right back on and stay on.

We will need to find out what is turning the screen on again. To do this please:

1. Wait until the screen turns off.

2. Wait until the screen turns on again by itself.

3. As soon as the screen turns itself on, run this command in a terminal:

   journalctl -b0 > curjournal.txt

   and send us the file 'curjournal.txt'.

Thanks for the quick reply.

Here ya go.

[Daniel van Vugt (vanvugt)]

Thanks.

Firstly, it looks like the amdgpu driver is repeatedly re-detecting your Samsung monitor. This might be a bug in the amdgpu driver, but might also be a faulty monitor connection.

Secondly, your "CM Storm Quickfire Rapid i" is being detected as only recently plugged in. So that would cause the screen to wake up.

Please try:

* A different monitor cable.

* A different keyboard, or just leaving the keyboard unplugged for a while.

And tell us if those stop the screen coming back on.

I'd point my finger a the amdgpu driver in that case. Unplugging the monitor in question did the trick (allowed system to blank properly). The cable is definitely good & the connection ports on both ends should be fine. This particular system is dual booted into Windows 10 where this is a non-issue.

The keyboard has always been wonky (frequently it doesn't get initialized and has to be unplugged and plugged in again). I left it plugged in to run the test & the system was not adversely affected.

The same amdgpu is plugged into two monitors:

[1] monitor with issue (straight HDMI <> HDMI) FreeSync compatible
[2] monitor that works fine (DP on gpu converted to HDMI) non-Free-Sync

Why is this still marked incomplete?

What other info is necessary?
