I recently installed 2015a to ubuntu 14.04 and it seems to have some problems, e.g. it is slow, ginput() not work properly, isosurface colour strange and some functions no longer in use (I don't want to change my codes since I have a lot to do). The same codes run perfectly on 2012b and on both unix and windows systems.

Yes, you can install previous versions of MATLAB (as long as they will work on your system.) You can have multiple versions of MATLAB installed at the same time.
If you have a current support contract, then you can download a previous version of MATLAB from the License Center.

You need to give the path to the shell script that sets up the environment variables and starts up the appropriate bin/matlab binary. Or at least you need to be in the appropriate bin directory when you start matlab, not at the matlab root directory for the installation.
