I'm new to this forum and thought I'd try it out. So, much like every edition since about 11.10 brightness control doesn't work "out-of-the-box". I have a Toshiba Satellite T110-12P and although I've managed to solve the problem in earlier editions, this time I cannot. I have tried adding the "acpi_backlight=vendor" kernel parameter but unlike other times, it did not solve the problem. I found a somewhat complicated solution by running some commands but I'd like to find a more comfortable one. Do you have any suggestions?
I have a solution that worked on my Acer Aspire V3-531G laptop with Ubuntu 13.04-64 bit. This solution does not depend on the hardware, hence I dare to recommend it to you:
Hope, this helps!
I have the same thing on one of my Toshiba-Satellite Laptops (the other one works fine). Brightness is always set to minimum after reboot. I couldn't find a real solution, so I installed a little brightness-indicator, which shows a button in the panel. After startup I can change brightness without the need to open system settings.
"Installing the applet in Ubuntu 11.10 through 13.04 is as easy as running the following commands in a Terminal:
sudo add-apt-repository ppa:indicator-brightness/ppa
sudo apt-get update && sudo apt-get install indicator-brightness
If a PPA is a bit too much for you, you can grab a .Deb installer from the project launchpad page"
You can find the details of the indicator at:
