KSW was having trouble running oXygen on Karmic (Ubuntu 9.10). Keystrokes would not generate characters in the editor for a second or two after being hit. The oXygen help file provided the solution:

Display problems like screen freeze or momentary menu pop-ups during mouse movements over screen on Linux or Solaris can be solved by specifying the parameter

-Dsun.java2d.pmoffscreen=false

for the Java virtual machine. This parameter disables off-screen pixmap support and must be added to the Java command line which starts the Java virtual machine at the end of the file oxygen10.3 located in the install directory.

We added this to both the oxygen and oxygen.sh files, grouping it with other similar parameters, and remembering to put quotes around it where required.
