    My screen goes black after a few seconds ubuntu 12.10

    Hi guys,

    Well here's the deal. I upgraded a week ago to the ubuntu 12.10 version. Turns out everything was fine until yesterday when my screen started to go black after merely 30/40 seconds.

    I went to the bettery/power app. put suspend whe inactive for in don't suspend and show battery never, is a desktop.

    Then went to brightness and lock and set the turn screen off when inactive for option in never, and lock the screen in off.

    rebooted the computer but still the system keeps going black in a few seconds, and suspends the system in about an hour.

    Thanks in advance.

    Already done that and there is nothing changed. I think I may need to change the grub or someother configuration from root or something.

    Install Caffeine and be done.

    i just thought of a possibility. Did you install an automatically changing background app. before this started? or/ Did you change screensaver settings?

    I don't know if the problem was there before or after putting one of the default autochanging walpapers. Anyway, I chosed another wallpaper, but the problem persist.

    I haven't installed an app to change backgrounds.

    edit: OK, You did NOT install an app. The default shouldn't cause this.


    The best idea is from wojox at post #5.

    I already installed caffeine. I had to install it via the terminal, because the software center or the synaptic didn't bring up anything. But i don't know what to do next. I tried sudo caffeine, but nothing.

    Did you install the PPA from that link? I assume you searched the dash?
