Looks like the backlight got turned off > at boot, I had to sleep it and wake it up to get it back. I've seen that since the first version. I also have to restart pbbuttonsd to make it work again after sleep. I keep logging in on tty1 to run 'fblevel 15'. Actually the backlight tends to turn off some time later, too. It's not just that it's off after sleep. -- dwmw2
