Having a problem with screen blanking in Fluxbuntu.

I recently started using Fluxbuntu on my old laptop, and it works great except for one issue. The system seems to save power by blanking the screen after 5 minutes or so. If I pause a video and leave it unattended, however, the screen won't come back up. I end up having to manually shut the system down.

Does anybody know how I can fix this? I've searched the Fluxbuntu forums and I can only find one post that relates to the subject. I can't find any screensaver or power management utilities - do I have to manually edit configuration files to solve this?

Thanks in advance for your help.

My laptop does something similar in Debian. I don't have a solution for you, but on mine, I can get the screen to come back on by switching to a virtual terminal and back (ctrl-alt-f1 and then ctrl-alt-f7)

I'm not that familiar with this particular flavour, but you could try disabling APM as per these instructions

Best answer: Not sure if it's the best solution for you, but you can affect the monitor power management using the 'dpms' option to the xset command. For example,
xset -display :0 dpms force on
would force the monitor to stay on (use 'off' to turn it off). To set it to blank after 5 minutes, it would be:
xset -display :0 dpms 0 0 300
See man xset for more information on the options.

Response by poster: That looks like it'll work. Would it be possible for me to write a script that would execute the "force on" command, start Totem, and execute the "300" command when I exit?

Best answer: Yes, you should be able to do that. For example, something like this in your .bashrc should work:

function totem
xset -display :0 dpms force on
/usr/bin/totem $*
xset -display :0 dpms 0 0 300

I have a similar problem with vlc--it disables the power saving when it starts, but doesn't turn it back on when it exits. I have something almost identical in my .bashrc, except with only the last xset and not the first, and it works fine so far.
