I just upgraded from Ubuntu 20.04 to Ubuntu 21.10 and then to Ubuntu 22.04.

After the upgrade whenever I try to open any pdf document via the terminal using xdg-open I get the following warning:

(evince:13596): dbind-WARNING **: 15:18:14.588: Couldn't connect to accessibility bus: Failed to connect to socket /run/user/1000/at-spi/bus_0: Permission denied.

I did not have this problem in Ubuntu 20.04 (I did not check this with Ubuntu 21.10). I find that because of this I do not get the nice list of sections/chapters in the left pane in doc viewer and it also does not keep track of the page number at which I left off a document.

Doing export NO_AT_BRIDGE=1 silences the warning but does not solve the problem.

I would like to be able to use the accessibility features which get disabled due to this error.

Any suggestions for fixing this problem are welcome.

NOTE: I am using Xorg with Ubuntu 22.04. I tried Wayland as well but the problem persists.

This is apparently a known bug in the community. Check this link.

Basically, if you don't need Accessibility features, you can just type in the following command in the Terminal:

export NO_AT_BRIDGE=1
