<pre>This is happening on Intel's generation 9 as well.
cpu: i3-6100
lspci: 00:02.0 VGA compatible controller: Intel Corporation Sky Lake Integrated
Graphics (rev 06)
As Luke has done, I've just done the following change to intel_hdmi.c
- if (INTEL_INFO(dev_priv)->gen < 7 || IS_IVYBRIDGE(dev_priv))
+ if (INTEL_INFO(dev_priv)->gen < 10 || IS_IVYBRIDGE(dev_priv))
This will hopefully fix the problem for me as well but as Luke says, it would
be nice if this got added upstream.
I should know by tomorrow if this change has fixed it. The behaviour has been
like this for me:
-monitor wakes up if it's been less than 1 or 2 hours
-monitor doesn't wake up the next morning, hence after a period of 8hours+
inactivity
I need to go back to a console and restart xdm in order to get the monitor to
wake up in X. (using xfce as DM)
I'm running on a 4.7 kernel which is the most recent, while the live_status fix
is still only valid for generations < 7.
Would have saved me some headaches if this had been fixed but ok :)
At least I'm glad this is a known issue.</pre>
