[ubuntu] X11 crashes when using gedit

view story

http://ubuntuforums.org – Hi, I am accessing my lab's server through my Macbook. The server is running Ubuntu 12.10. I am able to open gedit and make changes to text files, but whenever I save changes, X11 crashes, gedit shuts off, and I get the following error: HTML Code: (gedit: 11802): Gdk-WARNING **: gedit: Fatal IO error 11 (Resource temporarily unavailable) on X sever localhost:10.0. I think this has to do the other X11 warning message that I get. Whenever I log onto my server using ssh -X, I get this warning message: HTML Code: Warning: untrusted X11 forwarding setup failed: xauth key data no (Hardware)
