Are you trying to connect remotely? If you are, then you have to use "xhost" to give permission for remote X Clients to connect to your X Server computer. Remember, the X Server is the computer that is connected to the keyboard and mouse that you will be using. The X Client is the computer that runs the program. In other words, the X Server is the local computer, and the X Client is the remote computer.
Example 1: -------------------------------------- X Server hostname: xserver.local.com X Client hostname: xclient.remote.com On the X Server... [EMAIL PROTECTED]:~$ xhost +xclient.remote.com On the X Client (possibly using SSH login)... [EMAIL PROTECTED]:~$ export DISPLAY=xserver.local.com:0 [EMAIL PROTECTED]:~$ gimp & [EMAIL PROTECTED]:~$ -------------------------------------- NOTES: 1. This example assumes the display number used on the X Server is 0. The DISPLAY environment variable on xclient.remote.com should be "xserver.local.com:<display_num>", where <display_num> is the display number being used. 2. Host names can be changed to IP addresses instead. 3. I believe this should work. There may be firewall/NAT issues, but I don't know what ports need to be opened. 4. The '&' in the command "gimp &" is optional. Or, you could use SSH and do it the simple, secure way. Example 2: -------------------------------------- On X Server: [EMAIL PROTECTED]:~$ ssh -X [EMAIL PROTECTED] Password: [EMAIL PROTECTED]:~$ gimp & [EMAIL PROTECTED]:~$ -------------------------------------- Notes 2 - 4 apply to Example 2 as well. Hope this helps, Malcolm.
