Couldn't connect to accessibility bus

When using ssh with X11 forwarding, I am getting various errors and warnings when running gui applications.

As an example, any time I am running gitg, I get the following warning:

** (gitg:15904): WARNING **: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-ychCoQcrqT: Connection refused

Besides being ugly, does that suggest any real error?

I get the same warning running evince:

** (evince:16634): WARNING **: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-ychCoQcrqT: Connection refused

... or eog:

** (eog:16872): WARNING **: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-ychCoQcrqT: Connection refused

And so on.

Perhaps it worth mentioning: I am connecting from 12.04 to (yes, unsupported) 13.04.

Solution 1:

I don't think the warnings are important (unless you need the accessibility bus). Apparently forwarding the accessibility bus over SSH isn't supported yet.

However, you could try the following to suppress the errors if it annoys you:

Prepend the following to any commands:

NO_AT_BRIDGE=1

Or (a long-shot) try using the -Y option with -X in SSH to enable trusted forwarding.

Solution 2:

I had disabled conda with:

conda config --set auto_activate_base False
source ~/.bashrc

After this, when I started GDL, similar error was thrown at me. Fixed with:

conda init bash

Hope it works for others.
