OK with a little playing around I found that when I use the function keys to adjust the brightness the screen doesn't update but will used that setting after a reboot. i.e. set brightness to minimum and reboot brightness = minimum, set brightness to maximum reboot brightness = maximum.
After a few reboots and some trial and error I got it at a comfortable brightness. Hope this helps someone. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1196203 Title: the display brightness doesn't change (it is to the max) with Mir in ubuntu 13.10 Status in “xorg-server” package in Ubuntu: Triaged Bug description: I have used this guide http://www.olli-ries.com/running-mir/ to install and try Mir on a notebook Asus K55VD.
