This does not seem to have anything to do with either SSH or PuTTY.
You logged in as USER1. Your X-authentication credentials are in
the file ".Xauthority" under the home directory of USER1.
You changed to USER2, who is unable to read that ".Xauthority" file.
Worse, you changed the home directory, so that now a completely
different ".Xauthority" file is being consulted.
You need to look at the man pages for "xauth" to work out ways of
exporting the information so that it is accessible to USER2.
