I have Kubuntu installed on my Sony VAIO PCG-FRV25 laptop. One thing that had always bugged me is the backlight for the laptop display is by default in Kubuntu, set as null. A certain German diStribUtion which will remainS namEless, did a wonderful job of setting the brightness level at 8. It's amazing how much more distinct photos and backgrounds are with nice lighting. Captivating. So, I had to get Kubuntu to do that same. If you own a Sony VAIO PCG series, to change the default brightness for your panel backlight, type the following command
sudo kwrite /proc/acpi/sony/brightness
in the editor, enter a single number from 0 to 8. 0 is the null setting, no backlight, and 8 is the highest setting, crisp, clean and sharper graphics.
Save the document under it's current name and there you have it, instant change. To check out another setting, hit backspace and enter another. To activate the changes, save again. Enjoy your new found sunshine, and many happy times with Kubuntu!
