I wanted to install MATLAB 2015a on my laptop running Xubuntu 14.04. I have used 2014a on this machine with Xubuntu 12.04 before. In order to migrate my preferences, I first installed MATLAB 2014b, ran it once, then installed 2015a. The problem I'm facing is that MATLAB won't quit under some conditions. I'm not sure about 2014b, since I only ran it once and then deleted it again, so I can't check that anymore. I have renamed the preference folders in ~/.matlab to see if i could narrow down the problem and have come up with a way to reliably reproduce the error:
- open MATLAB and wait for the Ready status
- maximize MATLAB window
- open preferences
- close preferences
- click close button => nothing happens
- or run "quit" or "quit force" in command window => status changes to busy, but nothing happens
Now it get's a little fuzzy: sometimes MATLAB will quit normally after the next start, sometimes it will keep ignoring quit. Deleting ~/.matlab/R2015a always restores normal behavior.
There are many more conditions that result in MATLAB not quiting, in fact, I have to kill MATLAB almost everytime I do more than just open and close.
I'm downloading 2014a right now, to see if the problem occurs there, too.
UPDATE: R2014a quits without problems (and runs much faster).
