Public bug reported: On my Toshiba Satellite R830, I have 12.04LTS AMD64. The Fn + F6, Fn + F7 buttons reduce/increase the brightness level of the screen. The issue is that they stop working after waking my computer from sleep.
I found a workaround here : http://askubuntu.com/a/196863/27968 but I would like to have this problem solved properly. BTW I tried a 12.10 AMD64 live USB and the problem is exactly the same. I saw other similar bug reports but none with exactly the same symptoms.
