Re: raspberry PI - no X11

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.

Please make sure you have free disk space for the user to use,
and that the current user is owning ~/.Xauthority.

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.

Thanks, but the problem is not the pi password or ssh. I CAN
login over

ssh, but do not get X11. 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:
