I just installed GNOME 3 and this is a relatively fresh Arch install. I am using a ThinkPad X1 Carbon.
The problem I am having is that, the Fn+F8, Fn+F9 brightness control keys are not having significant effects. When I press Fn+F8, the GNOME shell brightness OSD does appear, and the bar does go down a bit, but it won't go anywhere lower even if I keep pressing Fn+F8. And when I run
[jiehan@tpx1c ~]$ /usr/lib/gnome-settings-daemon/gsd-backlight-helper --get-brightness 95
It is always 95. Using Fn+F9 to raise the brightness, I am able to get 100.
This is very awkward. I want to be able to set my brightness to something lower than 95 using keyboard shortcuts!
However, I am able to lower the brightness to < 95 by issuing the following, and it works:
[jiehan@tpx1c ~]$ sudo /usr/lib/gnome-settings-daemon/gsd-backlight-helper --set-brightness 50 [sudo] password for jiehan: [jiehan@tpx1c ~]$ /usr/lib/gnome-settings-daemon/gsd-backlight-helper --get-brightness 50 [jiehan@tpx1c ~]$
If you have any idea on getting the keyboard shortcuts to work, please let me know. Thank you!

There are a number of threads right now about Intel graphics and a bit of wonky-ness with the 3.8.3 kernels (and earlier it seems as these threads date back into Feb). Please search the threads for other relevant stuffs.
Thanks for the information... I just subscribed to this:
I will see if these are related.
