http://ubuntuforums.org – I don't use Ubuntu-One. I don't maintain an account on Software-Center either because I am constantly hounded to login every time I boot. Can I safely uninstall these applications: ubuntu-sso-client python-ubuntu-sso-client ubuntu-sso-client-gtk What exactly will not work right if I uninstall the above things? (Hardware)
