1. X11 & GUI installed in this way:  

   Code Block
   title X11 and GUI
   curl http://yum/centos-gui > /tmp/centos-gui /bin/sh /tmp/centos-gui

   (very large set of packages, takes a long time...)
   
   

2. Software installed via the GUI: Thunderbird, emacs, LibreOffice

   Code Block
   sudo gnome-software

3. Attempt to install FastX downloaded from www.starnet.com.  Code is unpacked from a tar.gz file and run without any special installation.  Attempt to configure SLAC but code fails with a relocation error associated with /lib64/libssl.so.10

4. TRS should not be used as it currently requires the use of DES enctypes that are insecure. WE have a todo to remove the ability for this weak-key to work. And are working to make TRS more secure so it can be used on Centos.
   
   

    

Configuration Hints

Desktop

The default desktop manager is gnome.  A large number of desktop settings are stored in the dconf database.  There are several ways to view/set these settings:

• From the Applications menu, select System Tools and then Settings.  Or, use gnome-command-center from the command line.  Not all settings are available in this way.  There is a second utility accessed via Applications -> Utilities -> Tweak Tools, which offers additional desktop configurations.
• The gsettings command provides access to all of the dconf DB
• The GUI app, dconf-editor, which is not included in the centos7 installation by default, is a graphical front-end to gsettings

For example, to increase the idle time interval until the screen blanks and locks to one hour:

$ gsettings set org.gnome.desktop.session idle-delay 3600
$ gsettings get org.gnome.desktop.session idle-delay
uint32 3600


and
 
$ gsettings set org.gnome.desktop.screensaver lock-delay 0
$ gsettings get org.gnome.desktop.screensaver lock-delay
uint32 0
