Hi everyone, how's it going? If anyone is having a problem with the screen brightness control in the power manager. If you have an Intel graphics card here a fix. First determine if you're using an Intel card. Run the following command in a terminal window:ls /sys/class/backlight/
If you're using an Intel card, the output should look similar to this:andy@sparkylinux-latitude:~$ ls /sys/class/backlight/
acpi_video0 intel_backlight
andy@sparkylinux-latitude:~$
If you're satisfied it's an Intel card, create the following blank configuration file, if it doesn't already exist. Enter the following command into the terminal window:sudo touch /usr/share/X11/xorg.conf.d/20-intel.conf
Do the password thing if asked, followed by entering the next command into the terminal:sudo mousepad /usr/share/X11/xorg.conf.d/20-intel.conf
Copy the following contents and paste it into the empty file:Section "Device"
Identifier "card0"
Driver "intel"
Option "Backlight" "intel_backlight"
BusID "PCI:0:2:0"
EndSection
Save the file and quit mousepad. Logout and back in < <This is important. Check the brightness controls and settings in the power manager. That's it, have fun ;)!!
