X11 remote application

[Richard_Romick]

I have two computers, a laptop running Ubuntu 14.04 64-bit and a desktop running Linux Mint 17.1 (virtualbox). I am working on being able to run both RSSOwl and Evolution on the laptop, but being displayed on the desktop. I can do this with RSSOwl just fine, but Evolution is much more difficult. This is what happens:

#sorry that senlis is my username on both computers, may make this somewhat difficult to follow.

senlis@senlis-VirtualBox ~ $ sudo ssh -Y senlis@192.168.8.6

Cannot start Evolution: Another Evolution instance may be unresponsive. System error: Could not connect: Connection refused

Does anyone know why this may be happening. Thank you,

What are the permissions of /tmp/dbus-hwkbPrwx0z? Perhaps loosening them up:

sudo chmod 777 /tmp/dbus-hwkbPrwx0z

and then try again. Of course this is temporary as /tmp gets wiped with each boot. Seems like an accessibility framework problem. Perhaps a Use Case where accessiblity is does not work correctly over an X-forwarded, ssh connection.

I think it is an x/windows permission issue - don't use sudo to remote into the other machine. Run ssh as the normal userid.
If you have been running GUI applications with sudo, there can be other permissions issues that have been caused by that too. You may need to clean up all permissions in the HOME on both computers.

I run it without sudo and it does the same thing. I have been running Thunderbird recently, since it works over the ssh connection. However, it does so with its share of errors, though it seems to work fine otherwise.
