I have this problem too, and it doesn't look like there's an easy solution. I have, however, whipped up a quick script to maybe solve this problem for some of you. It's not an ideal solution (you run the script once to turn the screen off, then again to turn it back on), but it'll have to do until the bug gets fixed. Here's a link:

Here's my workaround: http://monda.hu/blog/2010/01/12/lock...ubuntu-karmic/
It work if I have volume 0% for pulse audio!

Sorry false alarm I turn pulse volume on and it steel working... but it does not before...

Works perfectly fine! Thanks!!!
I have this same problem with Ubuntu Netbook Edition 10.04 on a Toshiba NB100
I think I know what the problem is: gnome-screensaver. If I run
on a terminal (the last bit inhibits the screensaver) then the backlight stays off (at least for a couple of minutes, which is what I've tried). This has the problem that now gnome-screensaver is inhibited even if I turn the screen back on (since it will stay inhibited until I cancel the command, e.g. by closing the terminal or hitting ctrl+c). But maybe someone has a good idea of how to go from here.Code:sleep 3 && xset -display :0.0 dpms force off && gnome-screensaver-command -i
might help to install the latest driver:

Bingo: it's gnome-screensaver. Here's one way to fix this:
Honestly who needs a stupid "screen saver" anyways, I'm not using a plasma display over here on my laptop, nothing is getting burned in. I just want something to turn off my display, which gnome-power-manager does already. Hopefully this is a better solution than the utterly insane option of running 'xset dpms force off' in an infinite loop.Code:sudo apt-get remove gnome-screensaver
Seriously though, people are piddling about with this bug on three different bugtrackers over the course of months and this is the first time someone's pointed out what the actual problem is. Sheesh.
