Aug 8, 2015 - Here's several ways to make the screen brighter. Than helpful, either leaving your screen too dark or too frequently adjusting the brightness. Your Acer computer monitor includes a menu that allows you to change various aesthetic settings, such as the contrast and brightness.

Optionally you can install XBACKLIGHTThe review:'For those of you whos laptop starts up with the screen brighter than the surface of the sun, this one is it. You can easily set this terminal program to stop your eyes from being bleeched by your laptop's screen brightness. Download the app, then go to the system tab, which is the cog shaped thing in the top right corner of your screen. Go to startup applications, and then set the command line to 'xbacklight -set 0' (or whatever percentage you want your backlight to snap to on start up) and obviously, remove the quotes from that command. Wallah, that should straighten all of those pesky backlight problems out. Tell your friends, because this one is a keeper'Edit: The following solution seems to work for some Acer Computers.GRUBCMDLINELINUXDEFAULT='quiet splash acpiosi=Linux i915.i915enablerc6=1'in /etc/default/grub (and then updating with sudo update-grub) the first option enables hardware control of backlight, the second implements a workaround for Intel graphicsSource. I've kept this thread bookmarked and I check it from time to time.
I finally found a way to solve this problem (for my hardware), so I'm writing this answer for archive and hopefully help someone else.I've been struggling with the same problem for nearly a year and a half. I have an Acer Aspire 5750G running Ubuntu 12.04.04 (64 bits), Debian Wheezy (64 bits) and Windows 7 Ultimate.The problem with the backlight sliding bar that should appear when hitting Fn+Left/Right arrow keys never worked for me except in Windows (I had to install Acer drivers after a fresh reinstall). I've put together something that seems to work using things I found here and in other places. First: get the widget to show upThis method worked both in Debian Wheezy and Ubuntu 12.04Edit /etc/default/grub and add at the end of the GRUBCMDLINELINUX line acpibacklight=vendor, and then run sudo update-grub2 (please notice the 2 at the end, since I'm using GRUB2). And this should work after next boot. Second: preserve backlightMake sure there's something in /sys/class/backlight.
I have there a symlink intelbacklight that points to././devices/pci00:00:02.0/drm/card0/card0-LVDS-1/intelbacklightThis folder has some files in it: $ cd /sys/class/backlight/intelbacklight$ lsactualbrightness blpower brightness device maxbrightness power subsystem type ueventWhen I dim the brightness, the value in file actualbrightness decreases $ cat actualbrightness976$ cat actualbrightness304$ cat actualbrightness160976 is the value in maxbrightness, and it's the max allowed value, so it won't go any further.I made a little script and tried to set it up as a cron job. It stored the value as it was supposed to but was unable to restore it on boot.A few days ago I found this book:So I made two upstart jobs to save and restore the value of the screen brightness.Upstart is packaged on Ubuntu since version 6.10 (I think) and is an option on Debian.Check you have upstart and its version: $ sudo initctl -versioninitctl (upstart 1.5)Copyright (C) 2012 Scott James Remnant, Canonical Ltd.This is free software; see the source for copying conditions.

The difference is that the values vary from 0 to 15, so, his 800 didn't work.The code is: pkexec /usr/lib/gnome-settings-daemon/gsd-backlight-helper -set-brightness 2I put this as a ' Startup applications.' (does not require root password) and now I don't have to configure every time after boot.One can get maximum brightness value for one's backlight with the option: pkexec /usr/lib/gnome-settings-daemon/gsd-backlight-helper -get-max-brightness.
I just built a new pc with Windows 8.1, an ASUS VG248QE monitor, and I'm using an ASUS GTX780-DC2OC-3GD5 video card. At night, I have my screen brightness set to zero, and I have an overhead light on in the room for ambient lighting, but the screen is still a bit too bright. It's not crazy bright, but it's too bright for my comfort level. Is there anything I can safely, easily, and cheaply do to make the screen brightness more comfortable without sacrificing picture quality or performance? Thanks for your help!
