Package Management: Package management is via yum and Yum-Ex. Yum-Ex’s interface is very clean, but it has some usability issues. This image shows what you see when you launch Yum-Ex – the updates window. Moving to the Available, Installed, and other windows tend to take too much time before the applications list is loaded. And if you do not install an application while in the search results window, it is not possible to return to the main window (I could not figure it out) without closing Yum-Ex and restarting it.

This just shows a list of applications by groups. Accessing Yum-Ex requires authentication, so you do not need to authenticate for every application you want to install, and you can queue applications for batch installation. Out of the box, the system is configured to check for updates after bootup, but I could not find any means to configure interval update checking.

Graphical Administrative Applications: All the graphical administrative applications are accessible from Menu > Administration, Menu > Preferences, and Menu > System Tools. Because LXDE has no control center, a central hub for graphical administrative tools, you need to authenticate for every application that requires it. Which means that if you need to use three different applications, you would need to authenticate as many times. I think a better solution would be to have a control center that would require authentication to start, so that you would not need to authenticate for every application you need to use.

The Task Manager is an application from the System Tools category. It displays some of the same information as the Process Monitor on a GNOME desktop. The system on which this image was taken had Firefox running with five tabs open, Gnumeric and Abiword, and two other applications were also open. Yet, it still showed a relatively small memory and CPU usage.

The LXDE Spin does not have the Users Account tool that is available on the Xfce Spin, but it shares the same Users and Groups management application, which is a fully-featured user management application.

It allows you to configure an account to expire at a future date. You may also lock the account’s password, which effectively disables the password. If a password is locked, the user cannot change the password.

And from the Password Info tab, you may enable password aging, or set the password to expire at a certain date.
