In Ubuntu Natty (11.04), you can try this https://launchpad.net/~patrick2000/+archive/pathos/+sourcepub/1946736/+listing-archive-extra ppa https://launchpad.net/~patrick2000/+archive/pathos/+packages package, which fixes it for me.
The problem, as I picked up somewhere, is that "xset dpms force on" / "xset dpms force off", which is ~ how gpm unblanks/blanks the screen, affects all attached screens. If the laptops built-in display is not turned off by the *hardware* (without help of gpm), gpm (I think :-)) turns it off via dpms when it is closed. Now if you blank the displays during idle time using dpms, they have to be unblanked at some time again. At that time, the internal display could now unintentionally be turned on as well (if it is not completeley turned of by the hardware anyway). I don't know how/if this is solved in oneiric. Phew... as said: works for me - and probably most other laptops. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-power-manager in Ubuntu. https://bugs.launchpad.net/bugs/550054 Title: External Monitor not Sleeping with Laptop Lid Closed Status in Gnome Powermanager: New Status in “gnome-power-manager” package in Ubuntu: Confirmed Bug description: Binary package hint: gnome-power-manager In Ubuntu 10.04, the gnome-power-manager seems to have no effect on my laptop. I am running my Toshiba laptop with an external monitor and the laptop LCD disabled. I've set the gnome-power manager to turn the screen off after 10 minutes (the time is actually irrelevant), but the screen will never turn off. It doesn't matter if I have the screensaver set to activate or not. It also doesn't matter how much time I tell the manager to wait before powering down the monitor. The monitor stays on no matter what.
