### Opening Java GUIs on the Awesome Window Manager (e.g. Matlab)

It seems that opening Matlab, Maple, and other programs that rellie in a Java GUI do not work properly when using the Awesome Window Manager. In all the cases the window is not loaded and a grey square is shown instead.

The problem seems to be that the Java Virtual Machine does not recognise this desktop when checking the system environment.

To solve the problem it is only necessary to change the appropriate environment variables to a known environment (e.g. LG3D). This can be achieved by installing wmname and running

wname LG3D


just before opening any of the applications.
