I have a desktop machine at home running Ubuntu 11.10 Oneiric Ocelot and which has encrypted home directories configured. I've also got a laptop that I mostly use. The desktop is configured to allow SSH login using OpenSSL authentication only - no passwords.
Earlier today, I attempted to login to the desktop from the laptop and open an X application, something I frequently do when the wife is logged in and using the desktop. I wasn't able to open the session, due to the following error:
X11 connection rejected because of wrong authentication.I quickly figured out that this was because I use the encrypted filesystem, so I mounted the filesystem manually, then tried again, and still received the same error when trying to launch my app. Can anybody advise? I don't get this error if somebody is already logged in on the desktop.
me@laptop:~$ ssh -X me@desktop

...I suspect that the key is in the xauth timeout and that I may need to manually run xauth. But I'm not certain with what arguments. OTOH, is there a way to force Ubuntu to automount the home filesystem? I.e., add my OpenSSL key as an "authorized" key to decrypt the filesystem?
Any help would be welcome. If there is already an answer to this, please feel free to point me in that direction.
Thanks.
