I'm also getting this problem on my Compaq Presario CQ60. Fn+F7/Fn+F8 don't work to set brightness (though other Fn keycodes generally work), and in fact I can't seem to find anything to set any value of brightness at all, and the computer seems to be stuck on the setting of "blindingly bright." /sys/class/backlight is empty, and the Xorg log doesn't mention "video" or "light" at all (other than in reporting the "acpi_backlight" kernel setting I tried; it didn't work). I'm using Ubuntu MATE 16.04. I'm... not sure how to post my specs, so I'm attaching a HardInfo report in case it helps :) Let me know if you need any more information, I'd love to see this bug fixed! (My eyes will thank you!)
