# How to resolve Start up error 502?

My Mathematica is not launching properly (I run it on Ubuntu 12.04 LTS). Here is the screenshot of the error message.

I've tried the following suggestions :

i) -cleanstart
ii) ~/.mathematica and even
iii) reinstalled it.


But none of the above is woking. Can anyone please help me?

Have you tried mathematica -cleanstart? –  Öskå Jun 9 '14 at 15:17
Yes. But showing the same error message. –  Biswajit Jun 9 '14 at 15:20
Have you reinstalled? –  Öskå Jun 9 '14 at 15:25
Still I haven't tried that option. –  Biswajit Jun 9 '14 at 15:31
It's quite easy to reinstall on Linux. See here for instructions around uninstalling. –  Öskå Jun 9 '14 at 15:33
