The issue - is that they stop working after waking my computer from sleep. + is that they stop working after waking my computer from sleep. BTW I + tried a 12.10 AMD64 live USB and the problem is exactly the same. - I found a workaround here : http://askubuntu.com/a/196863/27968 but I - would like to have this problem solved properly. + WORKAROUND: As root (not with sudo but actually changing user: su root), change the value in sys/class/backlight/intel_backlight/brightness . For instance: + echo 2937 > /sys/class/backlight/intel_backlight/brightness - 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. + These values are not between 0 and 7 (as the ones in the other + directory), but between 284 and 4539, or something like that.
