Comment 1 Aaron Lu 2014-03-19 07:18:41 UTC
Please attach acpidump and dmesg here.

Do you always have this problem or it starts to occur from some kernel version?
Comment 2 lee.joshwa 2014-03-19 14:12:29 UTC
Created attachment 130051 [details]
acpidump and dmesg results
Comment 3 lee.joshwa 2014-03-19 14:13:11 UTC
acpidump fails due to missing tables.
Comment 4 Aaron Lu 2014-03-20 01:47:00 UTC
grogg@envy:~$ acpidump > acpidump.out
Cannot open /dev/mem
Could not get ACPI tables, AE_ACCESS

You need to be root to access /dev/mem

acpidump

My mistake.  Here is a complete acpidump...
Comment 6 Aaron Lu 2014-03-21 01:21:32 UTC
Do you always have this problem or it starts to occur from some kernel version?
Comment 7 lee.joshwa 2014-03-21 01:54:47 UTC
This is persistent with all kernel versions.
Comment 8 Aaron Lu 2014-03-21 02:03:24 UTC
The ACPI dump shows that firmware doesn't provide a video output device that is capable of backlight control, so no chance for ACPI to create a backlight interface. The best bet would be the GPU driver to create a native interface, especially the firmware claims support of windows 8/8.1. Re-assign to GPU/i915.

Please provide dmesg with drm.debug=0xe module parameter set.

So there's an embedded display that is otherwise working when you captured the dmesg? It's an HDMI display, right? What does xrandr say?
Comment 12 lee.joshwa 2014-03-24 15:39:11 UTC
Correct on both parts. xrandr gives the following:

Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 32767 x 32767
VGA1 disconnected (normal left inverted right x axis y axis)
HDMI1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 510mm x 287mm
   1920x1080      60.0*+
   1600x1200      60.0  
   1680x1050      59.9  
   1600x900       60.0  
   1280x1024      60.0  
   1440x900       59.9  
   1280x720       60.0  
   1024x768       60.0  
   800x600        60.3  
   640x480        60.0  
   720x400        70.1  
VIRTUAL1 disconnected (normal left inverted right x axis y axis)

So basically you have an external HDMI display in the same all-in-one box. Looking from the outside, it sure looks embedded, but from the hardware and driver perspective it's an external display.

It is likely that DDC/CI is used for backlight control. See details in an otherwise unrelated bug [1].

This is not a bug in our driver.

After searching further into what you've just posted I've found that I can control backlight manually using:

'xrandr --output HDMI1 --brightness 1.0'

Where '1.0' can be changed between '0.0' and '1.0'.

Thank you for looking into this. I suppose I'll need to setup some keyboard shortcuts.

Confirmed with Chris, this just modifies the gamma curves. If it works for you, great, but it doesn't actually modify the backlight brightness.
Comment 16 lee.joshwa 2014-03-25 16:02:28 UTC
Yes, I understand that.  ddccontrol does not seem to be working, and I'm not concerned about power savings.  I'm simply looking for functional control of appearance.  There is actually a backlight control program in the ubuntu software center that adjusts for xrandr so I'm using it.  It's not exactly the fix I was looking for, but it will work.
