I have a system running bullseye. When I try to log out, or shut down, from MATE, I invariably get a popup that tells me that at-spi-dbus-launcher is not responding. I click on "logout anyway", and the system does eventually log me out, but there's a delay. I tried disabling the AT-SPI daemon and the Orca screen reader in my startup applications, but that hasn't helped. Does anyone know what's going on here? thanks, mike
