Hi Scott, thanks for the help! If you can apply the patch, we could see if you have the same behavior than Nate with his hardware: when setting a very low value (for him, it's in the range 1 to 5) to /sys/class/backlight/<hardware>/brightness his screen does not turn on at all. I would like to know if /sys/class/backlight/<hardware>/actual_brightness is then saying something different than /sys/class/backlight/<your hardware>/brightness. On my computer the backlight goes on as soon as I put 1 to /sys/class/backlight/<hardware>/brightness, so I cannot reproduce this. I hope I'm clear enough :) REPOSITORY R122 Powerdevil REVISION DETAIL https://phabricator.kde.org/D13095 To: thsurrel, #plasma, broulik, ngraham Cc: sharvey, zzag, ngraham, romangg, plasma-devel, ragreen, Pitel, ZrenBot, lesliezhai, ali-mohamed, jensreuterberg, abetts, sebas, apol, mart
