I had serious issues with screen brightness, the flickering on idle interrupted my Ubuntu installation twice. Without the tweak mentioned below any attempt to change brightness will result in backlight flicker and possible display freeze. In “Brightness and Lock” settings(in GNOME/Unity) disable “Dim screen to save power”. Remember to disable it again after completeing the installation.
After you install Ubuntu, you'll have to edit the GRUB config file. Here's how:
Open a terminal and type:
gksudo gedit /etc/default/grub
Find the line GRUB_CMDLINE_LINUX=”“ and add this between quotation marks: acpi_osi=Linux acpi_backlight=vendor
Save the file, and update grub (in terminal):
Restart your computer.
The display freeze issue should be fixed now, however you'll only be able to adjust the first two or three brightness levels, if you try to increase brightness further backlight will start to flicker again, display shouldn't freeze anymore though. You can adjust brightness using the following command:
sudo intel_backlight xx
Where xx is your desired brightness level (in %).
If you would like to be able to control brightness the usual way you can use this script:
#!/bin/bash backlight=$( sudo intel_backlight | tr -d "current backlight value: %" ) if [ "$1" = "up" ] then (( backlight=$backlight+11 )) sudo intel_backlight $backlight elif [ "$1" = "down" ] && [ $backlight -ne 0 ] then (( backlight=$backlight-9 )) sudo intel_backlight $backlight fi
For this script to work properly you should enable passwordless sudo for intel_backlight on your user account.
To do this use visudo, in terminal type:
sudo EDITOR=gedit visudo
You can replace gedit with any editor you like or skip the EDITOR variable if you're fine with vi.
Now that you are editing the sudoers.tmp file append the following line at the end:
Make sure to replace user with your own username.
Save the script with whatever name you like(for ex. brightness) and copy it to /usr/local/bin. Now you can adjust brightness using 10% increments with:
to increase or decrease brightness accordingly. You can also assign brightness up and brightness down to keyboard shortcuts of your choice.
Restarting bluetooth service
sudo service bluetooth restart
Works great, except the screen, but you can fix this, using tips above.
Bluetooth issue - I'm researching why. Restarting works great, though.
