You might encountered an issue saying "A fatal error has occurred and Cygwin/X will now exit" when you logged in to a new computer in GTIIT computer room. 

If you looked into the logs as mentioned, you would need to Make sure an X server isn't already running(EE) 

[   154.890] _XSERVTransMakeAllCOTSServerListeners: failed to create listener for local

[   154.890] (EE) Fatal server error:

[   154.890] (EE) Cannot establish any listening sockets - Make sure an X server isn't already running(EE)

[   154.890] (EE) Server terminated with error (1). Closing log file.

Please restart your PC then use your GTIIT account to re-log in and try to run Cygwin, it should be working well in this way. It seems to be due to previous session was still running an X server even after the previous user has logged out.
