78.6 Issue: Monitor not Sleeping\Ubuntu 11.10 [111210]
With Ununtu 11.10 upgrade on Nyx the power management using gnome-screensaver did not put the monitor into power saver mode (Dell E2209W flat screen LCD display). Instead, it seems to simply blank the screen and in a dark room we can still see that the screen is on, blanked, rather than off. This was not a behaviour noticed prior to Ubuntu 11.10. Previously the screen would go into power saver mode and the green led would go orange. To revert to an older screen saver to ensure the screen is completely turned off, we need to change some packages.
First, remove gnome-screensaver:
If you are currently running a GNOME session you will also want to stop the currently running instance of gnome-screensaver:
Next, install xscreensaver and friends:
The new screen saver will not start automatically when you log in—it
needs to be added to the Startup Applications. To do this go to the
Control menu at the top right of the screen. Choose
Startup Applications…. Click the Add button. Name
the new entry Screen Saver and type in the following
Command:
Using Dash (press and release the Super key)
to startup the Screensaver application. I tend to use
Blank Screen Only Mode under the tab and then enable on the Advanced tab. This way I don’t use
unnecessary power displaying a screen saver and my screen now goes
into power saver mode immediately.
