Hi.

I installed Matlab R2014a 64bit in Ubuntu 13.04 64bit. Last month I designed a program with GUIDE in windows Matlab. Now I want use it in Ubuntu Matlab but all elements in Gui figures is like a disaster. Position of buttons and other elements in GUI changed. Style of buttons and other elements changed. The GUI window now is Gray!. The size of GUI windows changed. when I open GUI in guide every think is good. The size is OK but when I run it I can't see a part of window that is beyond the screen size of display (that part cuts from window).

When I checked java version with 'version -java' in windows, it is : Java 1.7.0_11-b21 with Oracle Corporation Java HotSpot™ 64-Bit Server VM mixed mode.

I checked it in Ubuntu Matlab and it is the same. My destined program is working properly in windows.

I changed Unity to classic gnome. Nothing changed. I have same problem.

What should I do for this problem?

Thanks.

Another problem. When I connect java to new java and run it I have this error :

Fatal Error on startup: Cannot locate or initialize class com/mathworks/jmi/OpaqueJavaInterface. java.lang.UnsupportedClassVersionError: com/mathworks/jmi/OpaqueJavaInterface : Unsupported major.minor version 51.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClassCond(ClassLoader.java:631) at java.lang.ClassLoader.defineClass(ClassLoader.java:615) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:141) at java.net.URLClassLoader.defineClass(URLClassLoader.java:283) at java.net.URLClassLoader.access$000(URLClassLoader.java:58) at java.net.URLClassLoader$1.run(URLClassLoader.java:197) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247)

I'm downgrading java 1.7 of Matlab R2014a to 1.6

Thanks.

And if you put back java 1.7?

When I use downloaded java 1.7 with terminal and connect it to Matlab there isn’t any problem so I think the problem is only in downgrading it to 1.6.
