Can't adjust brightness on new Dell laptop

[JasonMichael]

Hi gang,

Thanks for such a helpful forum. I've got a new Dell Inspiron 11 3138 that I've got fully working except for the backlight. Pressing the FN keys brings up the OSD but doesn't adjust anything. Neither does the slider.

I've tried several options, including the suggestions here: https://wiki.archlinux.org/index.php/Ba ... ernel_3.13

In /sys/class/backlight/ there are two folders, acpi_video0 and intel_backlight.

Any ideas? Thanks for your help!

Specs: Dell Inspiron 11 3138, Mint 16, Kernel 3.14.1

I followed the last answer and it worked for me.
