Since upgrading to 13.10, I no longer have the 'privileges' to do the following things:
- Mount USB/CDROM drives
- Run software centre or software updater
- Press the GUI shut down or restart buttons
- Unlock my account in the 'settings - user accounts' section (padlock is greyed out)
Also, when logging on as a guest user I get error messages relating to Compiz crashing with SIGSEGV and it hangs on a blank wallpaper screen.
However, I still am able to use sudo in the terminal.
Output of 'groups' is
jenchris adm dialout cdrom sudo audio video plugdev lpadmin admin pulse pulse-access sambashare
sudo usermod -U username doesn't have any effect
