GNOME Bugzilla – Bug 728498
Brightness slider discrepancy at boot

Created attachment 274665 [details] Gnome-shell brightness discrepancy System-status menu incorrectly claims screen brightness is at 0%. Gnome-control-center reports the correct brightness level. Please see screenshot for detail.
I have the same problem with Gnome 3.12. Worked fine on 3.10. Issue appears on both Fedora and Arch once upgraded to 3.12. Brightness slider at 0 on boot but actual brightness is 100%. Once clicked it works as expected. Running on Intel HD 3000.
