What is the purpose of At-Spi?

Asked by Pierre on 2012-11-06

Since upgrading to Lubuntu 12.10, I have two new services running:
at-spi-bus-launcher
at-spi2-registryd

What is the purpose of at-spi? Who needs it and can it be disabled safely?

Thanks.

Have you read the man pages?

Nothing at: man at-spi. I have not found a satisfactory answer on the Internet either.

Hi ,
at-spi-bus-launcher
is a
bus launcher

AT-SPI uses its own D-Bus bus, in order to handle accessibility of administrative applications. There is a program called at-spi-bus-launcher to manage the lifecycle of this bus and provide a method for retrieving its address.

Source is here: http://www.linuxfoundation.org/collaborate/workgroups/accessibility/atk/at-spi/at-spi_on_d-bus#buslauncher

Another source here: http://www.linuxfromscratch.org/blfs/view/svn/x/at-spi2-core.html

I hope your question been answered

Thanks

This is very technical do me and to probably a lot of other people. What is a bus, what is D-bus? Etc. I would appreciate someone to elaborate on this.

The bottom line is what applications it would affect, only screen readers & magnifyers?

And, can I uninstall it safely. For example, on a Lubuntu standard install would it create problems if I uninstalled it?

What is D-bus ?

If you want any information about a package (in your Ubuntu) , is enough to now the name and then give this command

~$ apt-cache show <package-name>

For at-spi2 see

~$ apt-cache policy at-spi2-core

I don't now exactly if you will encounter any problems (probably no , because is an optional package referred to Gnome and you said you have Lubuntu) , maybe they have pre-installed this package for some Gnome-Applications compatibility. Perhaps you will encounter problems with some gnome-applications , not sure.

Thanks

Can you help with this problem?
