Matlab 2015B freezing on startup screen

Matlab 2015B freezes on the startup screen with a fresh install of Ubuntu 14.04. A week ago it worked with 14.04 and Matlab 2015A. I have started it using the code "matlab -nodesktop" and I get the following errors:

Can't reload '/usr/local/MATLAB/R2015b/bin/glnxa64/libmwhgbuiltins.so'

Error in connector.internal.autostart.run

Error in connector.internal.autostart.run >> Exception in thread "AWT-EventQueue-0" java.lang.RuntimeException: com.mathworks.services.settings.SettingValidationException: IMsgIDException for "matlab.workingfolder.LastFolderPath": Internal Error: No write permission on directory /home/tomas/.matlab/R2015b/temp0x3730x208c.

Any help would be greatly appreciated. I activated the product using my user name tomas and the file libmwhgbuiltins.so has read-only access by all other users. Thank you in advance.

Hi, I have the exact same issue on Centos 7. Here is how I solved the problem:

cd /usr/local/MATLAB/R2015b/bin/glnxa64/
ldd libmwhgbuiltins.so | grep libX

in my case, it states

libXt.so.t6 ==> not found

so I just

sudo yum install libXt

and the problem is gone.
