Hello, I'm using debian jessie with some backports too and I think I am affected by the same underlying issue, I'm not quite sure if "change linearly without light off" means what I'll describe as "flickering". I am using an IBM Lenovo ThinkPad T61 and gnome 3.14.
When I upgraded xserver-xorg-video-intel from 2:2.99.917+git20160706-1~bpo8+1 to 2:2.99.917+git20161105-1~bpo8+1 I noticed a "flickerig" in the backlight brightness whenever I changed it via the hot keys. It is still occuring with 2:2.99.917+git20161206-1~bpo8+1. As the upstream bug report has the staus NEEDINFO and it is requested to "reproduce using *only* /sys/class/backlight/intel_backlight/brigthness directly" I played arround with different methods of brightness adjustion. First of all a better description of what I mean with "flickering": on each key press of the hot key the brightness is adjusted, however there is a short period (maybe 1/10th of a second) where the backlight is set to some other level. This is happening in both directions, but not when the minimum or maximum is reached. When I write values to either /sys/class/backlight/intel_backlight/brigthness or /sys/class/backlight/acpi_video0/brightness this flickering doesn't occur. Also, when I fade the brightness in the gnome menu (upper right corner for me, below the volume settings) it changes perfectly without flickering. This lets me assume that is not a (pure) upstream issue, but more likely an issue with the hot key management and its interaction with xserver-xorg-video-intel (I assume that happens somewhere else and no in xserver-xorg-video-intel, doesn't it?). Therefore I share this findings here and not in the upstream bug. If you'd like I can also post it there. ---- 1. tune down brightness in gnome and hit brightnessdown key multiple times to get to a dark state root@my-host:~# cat /sys/class/backlight/acpi_video0/brightness 0 root@my-host:~# cat /sys/class/backlight/intel_backlight/brightness 0 2. tune brightness up to maximum in the gnome menu (backlight changes seamlessly to the brightest state) root@my-host:~# cat /sys/class/backlight/acpi_video0/brightness 0 root@my-host:~# cat /sys/class/backlight/intel_backlight/brightness 12056655 3. hit brightnessdown key few times (extreme flickering: backlight is always shortly dark) root@my-host:~# cat /sys/class/backlight/acpi_video0/brightness 0 root@my-host:~# cat /sys/class/backlight/intel_backlight/brightness 9042444 4. hit brightnessup key few times (less extreme flickering) root@my-host:~# cat /sys/class/backlight/acpi_video0/brightness 2 root@my-host:~# cat /sys/class/backlight/intel_backlight/brightness 10248157 5. go back to default level, as in 1. root@my-host:~# cat /sys/class/backlight/acpi_video0/brightness 0 root@my-host:~# cat /sys/class/backlight/intel_backlight/brightness 0 6. tune brightness up via echo to intel_backlight (backlight is in its brightest state) root@my-host:~# echo 12056655 > /sys/class/backlight/intel_backlight/brightness root@my-host:~# cat /sys/class/backlight/acpi_video0/brightness 0 root@my-host:~# cat /sys/class/backlight/intel_backlight/brightness 12056655 7. hit brightnessdown key once (backlight is immediately dark) root@my-host:~# cat /sys/class/backlight/acpi_video0/brightness 0 root@my-host:~# cat /sys/class/backlight/intel_backlight/brightness 0 8. tune brightness up via echo to acpi_video0 (backlight is in its brightest state) root@my-host:~# cat /sys/class/backlight/acpi_video0/brightness 15 root@my-host:~# cat /sys/class/backlight/intel_backlight/brightness 12056655 9. hit brightnessdown key once (backlight is immediately dark) root@my-host:~# cat /sys/class/backlight/acpi_video0/brightness 14 root@my-host:~# cat /sys/class/backlight/intel_backlight/brightness 0 ---- So the problem seems that the brightness levels are inconsistently changed by the hot keys. I noticed https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=801348#12 and added Option "Backlight" "intel_backlight" to the Device Section in xorg.conf, however that made no difference.
