Xfce is the default Desktop Environment on all CLASSE Scientific Linux 7 (SL7) systems.

From the xfce.org site:

"Xfce is a lightweight desktop environment for UNIX-like operating systems. It aims to be fast and low on system resources, while still being visually appealing and user friendly."

For a tour of the main features of Xfce 4.12 version used at CLASSE, please see the xfce.org 4.12 tour page.

Xfce avoids issue with running Multiple Sessions on Linux

Both KDE and Gnome suffer from NFS locking issues when the same user account is simultaneously running multiple sessions, across multiple computers. Xfce avoids thess problems, thus is recommended for both the local destop and a remote session via X2Go.

For additional notes on running multiple sessions at once, please see MultipleSessions.

To use Xfce with X2Go, please see the intro to x2go wiki.


XFCE Panels

If your panels aren't opening or displaying properly:
  1. open a terminal and type xfce4-panel Rebooting would do the same thing, if that’s an option.

If that doesn't work, open a terminal and type the following commands.
  1. xfce4-panel --quit
  2. pkill xfconfd
  3. rm -rf ~/.config/xfce4/panel.
  4. rm -rf ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-panel.xml.
  5. xfce4-panel

Desktop Reset

If the above doesn't work for fixing your XFCE Panel or you want to reset your XFCE Desktop entirely,
  1. logout
  2. open a terminal using X2Go, NoMachine, or by ssh'ing in.
  3. type rm -rf ~/.config/xfce4 && rm -rf ~/.local/share/xfce4
  4. exit your ssh session, and log back in graphically.

Manually trigger the transparent screen lock from Xfce:

  • right-click on a panel, select “Panel”, and choose “Add New Items”
  • select Launcher, and click Add
  • right-click on the new launcher, and click properties
  • click the icon for “Add a new empty item”
    • - Name = xautolock
    • - Comment = xautolock
    • - command = /usr/X11R6/bin/xautolock -locknow
    • - Pick icon of choice
  • click Save
