I've made another, even more severe observation.
I'm running a rather mixed setup using lightdm, xfce4-session and kwin as window manager, started via the session Client0_Command way. One of the issues I recently had was a freeze at session startup, disallowing any login unless I reverted to xfwm4. While bug hunting again, I tried killing at-spi-bus-launcher and at-spi2-registryd while still on the lightdm login screen, and after that, I could log in again without any issues. Another workaround that seems to do for now is to disable accessibility via gsettings: gsettings set org.gnome.desktop.interface toolkit-accessibility false By that option, QT_ACCESSIBILITY never gets set. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
