Hi, I installed a new modem. It has a wired ethernet connection to my PC. But now, every time I start an application in X, this message shows up in the terminal where it was started from: Authorization required, but no authorization protocol specified Authorization required, but no authorization protocol specified And those applications take much longer to start. For example, evince used to start in half a second without leaving any messages in the terminal. Now it takes about a minute, leaving lots of messages, see below. Searching the internet, my impression is that it has something to do with the hostname. /etc/hostname is empty. Is that normal? I also have Debian on my machine, but this phenomenon does not show up there. Any idea what could cause this? When starting evince from an x-terminal, these are the messages that show up: Authorization required, but no authorization protocol specified Authorization required, but no authorization protocol specified ** (evince:5473): WARNING **: 12:49:52.808: AT-SPI: Could not obtain desktop path or name ** (evince:5473): WARNING **: 12:49:52.817: atk-bridge: get_device_events_reply: unknown signature ** (evince:5473): WARNING **: 12:49:52.817: atk-bridge: GetRegisteredEvents returned message with unknown signature ** (evince:5473): WARNING **: 12:49:52.830: AT-SPI: Could not obtain desktop path or name ** (evince:5473): WARNING **: 12:49:52.838: AT-SPI: Could not obtain desktop path or name ** (evince:5473): WARNING **: 12:49:52.838: atk-bridge: get_device_events_reply: unknown signature ** (evince:5473): WARNING **: 12:49:52.838: atk-bridge: GetRegisteredEvents returned message with unknown signature ** (evince:5473): WARNING **: 12:49:52.838: AT-SPI: Could not obtain desktop path or name ** (evince:5473): WARNING **: 12:49:52.844: AT-SPI: Could not obtain desktop path or name ** (evince:5473): WARNING **: 12:49:52.844: atk-bridge: get_device_events_reply: unknown signature ** (evince:5473): WARNING **: 12:49:52.844: atk-bridge: GetRegisteredEvents returned message with unknown signature
