Zend Studio opens with no menu

when this happens, the instructions to fix it are here: http://www.zend.com/support/knowledgebase.php?kbid=241&view_only=1 but you can follow them below:

Symptoms



When running Zend Studio:
1. The ZS's main window comes up totally empty.
2. Sometimes the window has some of the frames painted, but the rest of the window is empty.
3. In the empty ZS window the mouse cursor is changing while moving around the window (as if there are objects: like buttons and other objects).
4. There were erratic mouse/window movements reported.


Summary



Zend Studio starts up with various windowing GUI problems in some linux distros, while using the XGL-Compiz/Beryl product.


Cause



1. Incompatibility between the XGL environment, the JRE, and the Zend Studio Client.
2. The decoration in the 3D environment clashes with the Java Runtime and distorts the operation and visualization of the Zend Studio client's window.


Workaround



There are two ways to execute Zend Studio, by running the ZDE script, and by running the runStudio_unix.sh script, both are in the bin directory of zend studio
(usually /usr/local/Zend/ZendStudio-/bin)

The following workarounds may be used, but there is no guarantee how well or how long it might work for you in your environment.


modification of ZDE script for xgl:


1. Open your ZDE script with your favorite editor
2. add the next line of code at line 1693.
options="$options -Dawt.toolkit=sun.awt.motif.MToolkit"

for example:
1693:
1694: debugOut ""
1695: unset POSIXLY_CORRECT
1696: if [ $DO_NOT_FORK ]

becomes:
1693: options="$options -Dawt.toolkit=sun.awt.motif.MToolkit"
1694: debugOut ""
1695: unset POSIXLY_CORRECT
1696: if [ $DO_NOT_FORK ]

3. Save the file.


modification of runStudio_unix.sh script for xgl:


1. open the the file in your favorite editor.
2. modify the java execution line,
the line starts with: ../jre/bin/java -Xms16m -Xmx256m -cp...
change it to: ../jre/bin/java -Dawt.toolkit=sun.awt.motif.MToolkit -Xms16m -Xmx256m -cp...
^^^^^^^^^^^^^^^^^^^^^^^^^^
as you can see, the only difference is an extra parameter to the java program.
3. Save the file.

Another solution



the AWT_TOOLKIT environment variable can be set in order for Java to choose a working AWT Toolkit.

export AWT_TOOLKIT="MToolkit"

In most Linux Distributions it's enough to append this line to /etc/profile.
