Greetings everyone;
For the past decade and change, when I wanted to do a poweroff code
test/preview, I have been able to open an sss -Y machinename session and
start a graphical heavy program with all the X stuff sent back to this
big iron machine with a nice comfy chair in front of the keyboard.
But I updated this machine to wheezy, debian 7.8, a couple months back
and hadn't had a good excuse to do that, although I had been able to run
a session of update-manager by that means.
I just tested that again, it works from the shop machine which is based
on the ubuntu 10.04-4 LTS install, but not from the lathes machine which
has a new install on it that is, with the exception of a pinned kernel,
pretty much straight wheezy and updated daily.
The error I get when I attempt to run via this ssh -Y machinename link, a
session of update-manager is:
gene@lathe:/lib/firmware$ sudo update-manager
[sudo] password for gene:
X11 connection rejected because of wrong authentication.

When I try to run linuxcnc on either of those machines, the X display
remoting fails, but with a slightly different error.

So my questions is, what fixes this?
Thanks all.
