    Karmic: Display not going to DMPS sleep correctly

    My problem: The LCD display on my laptop wouldn't always go to DPMS sleep. Sometimes it did, sometimes it didn't.
    I tried: All sorts of fixes including updates to xserver and gnome-power-manager ... but no luck.
    What I did that worked: Decided to try replacing "gnome-screensaver" with "xscreensaver", disabling DPMS sleep in "gnome-power-manager", and enabling DPMS sleep in "xscreensaver" ... and it WORKED!

    Step 1:
    *Open "Administration->Synaptic Package Manager"
    *REMOVE package "Gnome-Screensaver"
    *INSTALL package "xscreensaver"
    *INSTALL package "rss-glx"
    *INSTALL package "xscreensaver-gl"
    *INSTALL package "xscreensaver-data"
    *INSTALL package "xscreensaver-gl-extra"
    *INSTALL package "xscreensaver-data-extra"
    *Close Synaptic Package Manager

    Step 2:
    *Open "Administration->System Monitor"
    *Find the process "gnome-screensaver" and KILL it
    *Close System Monitor

    Step 3:
    *Open "Preferences->Startup Applications"
    *Find the startup application "Screensaver" and select it
    *Click the "Edit" button to the right
    *Replace the text "gnome-screensaver" with "xscreensaver -no-splash" and click the "Save" button
    *Close Startup Applications

    Step 4:
    *Open "Preferences->Power Management"
    *Under "AC" and "Battery" tabs, set "Put display to sleep when inactive for" to "Never"
    *Close Power Management

    Step 5:
    *Open "Preferences->Screensaver"
    *When prompted to start xscreensaver daemon, allow it
    *Under the "Display Modes" tab, select SOME screensaver or select "Blank Screen"
    *Below that, set the "Blank After" time to some desired time (this is how long until the screensaver activates)
    *Under the "Advanced" tab, check the box for "Power Management Enabled"
    *Below that, set the "Standby", "Suspend", and "Off" times to some desired time (this is how long until the monitor shuts off. In my case, I just set all the fields to the same time ... 5 minutes)

    That SHOULD be it! It fixed all the problems with my display not doing DPMS sleep, AND it gave me a lot of nice screensavers to choose from. Hope this works for you! =)
