Re: ERROR: Cannot open X display
Thank you for your response. Now, the question is what are the exact steps (if there are any) to actually get this to work? Luis G.

ERROR: Cannot open X display
I have used Cygwin/X on two computer in my office and it works with no problems. There are several users who cannot use the softwared. One in particular gets the following error messages: ERROR: Cannot open X display. Check display name/server access authorization. ERROR: Explorer failed to initialize. ERROR: Cannot open X display. Check display name/server access authorization. ERROR: Cannot open X display. Check display name/server access authorization. ERROR: Explorer failed to initialize. This is the steps that I use in my office to run Cygwin/X: 1. Execute “startxwin.bat”. 2. On the window that opens I type: xhost + hostname.temple.edu. Then I type: ssh –X [EMAIL PROTECTED] 3. I type my password and get in with no problem. Then I type: setenv DISPLAY myipaddress:0.0. 4. After that I execute SAS by typing SAS. Then SAS starts. In the computers in my office it works fine. In other computers the above message is displayed after I type SAS. I have verified the IP address. Specs: • OS: Windows XP Professional. • Cygwin/X was installed from the setup.exe file located at: http://x.cygwin.com/. • The system I login to is a UNIX system. • User is an administrator. Any suggestions? Luis G. Rivera Senior Tech Support Specialist Computer Services Help Desk Luis G. Rivera Senior Tech Support Specialist Computer Services Help Desk
