[SOLVED] LightDM and Active Process

Horizon_Brave · 2015-11-29 19:52:41

Hiya folks. I usually (as of two days ago) have a running htop window open, just so I learn about about what's 'normal' and what's more unusual. Anyway I've seen the lightdm user, popping up about every 30-60 seconds. The command being triggered is /usr/lib/at-spi2-core/at-spi2-registryd and or /usr/lib/at-spi2-core/at-spi-bus-launcher

Is this normal to occur after you've logged in (which is past the lightdm process of logging in) It's usually absolutely minimal resources, I'm just curious as to the purpose of these at-spi registries and bus-launcher.

I'll leave it to experts for the specifics of your question, but remember you are running a lightdm openbox session, so there is much more going on than just a login.

@Horizon_Brave,

I found this, hopefully it will be of some relevance to your question:

at-spi2-core is the base package for GNOME Accessibility which provides assistive technologies for people with disabilities (screen readers and magnifiers, on-screen keyboards, speech recognition, etc...)
https://packages.debian.org/jessie/at-spi2-core
https://wiki.gnome.org/Accessibility/IntroATs

We included it in our ISOs because, what, were going to make someone visually impaired go hunting for accessibility base-packages? I don't run it on my system as it's another daemon I don't need, but it's a very tiny load on resources and its absence will cause the GTK3 apps in BL (network-manager, evince, transmission, catfish, etc...) to create a slew of errors in ~/.xsession-errors. To remove...

sudo apt-get purge at-spi2* && sudo apt-get --purge autoremove

Thanks Panda, you're link, led me to this as well which pin points a lot of start up processes and their definitions:

Thanks hhh! I just missed your reply, but that answers my question exactly! Much appreciated
