The keyring is causing me no end of problems. How do I uninstall it?
I'm not sure whether that's a good idea, some package or group of packages might be using it to store credentials, I mean, is there for a reason, isn't it? What problems exactly? Are you using auto-login and being constantly asked for a password when launching some programs, i.e. a web browser?
