Example for the KDE desktop:
Launch the "KDE Control Center" utility. Sometimes this is called
"Personal Settings".
Select "Desktop".
Then Select "Window Behavior". In the "Moving" Tab set these:
* YES - Display content in moving windows
* YES - Display content in resizing windows
* NO - Display window geometry when moving or resizing
* NO - Animate minimize and restore
In the "Translucency" Tab set:
* NO - Use translucency/shadows
Next hit "Back" and then select "Panels".
In the "Appearance" Tab set:
* NO - Enable icon mouseover effects
* NO - Enable transparency
Now go all the way back up to the top and Select "Appearance &
Themes".
Select "Background" and set:
* YES - No picture
* Colors: Single Color
Select "Fonts" and disable anti-aliased fonts if you are bold enough.
Select "Launch Feedback" and set:
* Busy Cursor: No Busy Cursor
* NO - Enable taskbar notification
Select "Screen Saver" and set:
* Screen Saver: Blank Screen
Select "Style" and in the "Effects" Tab set:
* NO - Enable GUI effects
Example for the GNOME desktop:
* TBD.
