Re: raspberry PI - no X11

[Moish]

Check the memory card. I quit using Pi due to frequent problems with various mem cards. I kept regular backups and images just to repair the problems.

Make sure that you didn't touch ForwardX11Timeout setting for sshd.conf. This can also be caused by selinux To verify it is not a user restriction, add a brand new user with a home dir under /home  and see if you can do ssh -X Client side: make sure you can ssh -X to other hosts.

And this is exactly what happens when I connect a monitor and keyboard directly to the PI. Just in case, I added -v to the ssh command as you suggested and here are the last few lines of the output: debug1: Next authentication method: password pi@pi's password: debug1: Authentication succeeded (password).
