You may have noticed the blanking of screen after an idle timeout. This may be annoying while you are watching a movie. So If you want to disable the X screen blanking that comes up unexpectedly while you’re watching a movie in MPlayer or ...,

I led an Ubuntu Open Week session earlier this morning on screen-profiles. As part of the session, I setup a demo on an Amazon EC2 instance running Ubuntu 9.04.

GDM (GNOME Display Manager) is a highly configurable reimplementation of XDM, the X Display Manager. It starts the X session and shows a login window to the user.
Ubuntu 11.10, the latest stable release of the popular Linux distribution, sports two guest accounts, one in the login screen and the other accessible from an active user session. Both are tightly coupled to LightDM, the new display manager.
The screen lock of openSUSE 11.2 can be bypassed by the simplest of means. A reader's report prompted The H's associates at heise Security to investigate. Tests confirmed that a locked desktop session can be unlocked without password by holding down the return key. This causes the GNOME screen saver to crash and unlock the desktop after only a few seconds.
Do you get annoyed when you have a SSH session open, visit your browser for a while, and then return only to find you were disconnected? Most home NAT routers are the cause of this. If your router doesn’t offer an option to not shut off idle connections, you are probably better off by setting a keep-alive setting.
Fathers Day, and the end of my Gnome-Shell series. I still find it surreal to log into a session running Gnome-Shell and see a desktop devoid of familiar features. Gnome-Shell is the new direction Gnome is going for release 3, and Ubuntu seems set on following suit. Will this be a smart move?
