Title:
Intel Video Backlight keys do not work out of the box on Dell
Precision 7510
Status in linux package in Ubuntu:
Confirmed
Bug description:
After following https://wiki.ubuntu.com/Kernel/Debugging/Backlight I
have these results regarding when backlight controls (on laptop AND on
an external keybaord) operate in either GDM (login screen) and/or XFCE
logged in session:
With GRUB_CMDLINE_LINUX set to:
* no options: GDM but not in XFCE session
* acpi_backlight=vendor : neither
* video.use_bios_initial_backlight=0 : GDM but not session (system seems
slower)
* acpi_osi= : works in both (sometimes doesn't after reboot, possibly if not
plugged in)
* video.use_native_backlight=1 : gdm but not session
* /usr/share/X11/xorg.conf.d/80-backlight.conf : works in both. Default XFCE
background image looks funny (vertical stripes).
XFCE power manager's backlight brightness level indicator appears and
changes with all of the above (but actual backlight brightness only
changes with some of the settings as mentioned above)
`echo 8 > /sys/class/backlight/intel_backlight/brightness` seems to
always work.
