    Running x applications from the terminal

    Hello,
    I'm having a bit of trouble running x applications in the terminal since upgrading to dapper.

    In root-shell terminal sessions, I get "cannot connect to X server" for any x application I try and run.

    In the normal shell I get the following errors, but the application will still run:



    ~$ krusader
    X Error: BadDevice, invalid or uninitialized input device 168
    Major opcode: 145
    Minor opcode: 3
    Resource id: 0x0
    Failed to open device

    ~ScimInputContextPlugin()


    Anyone any ideas what is happening here?
    Cheers

    Re: Running x applications from the terminal

    Logging in as root, even in shells, is discouraged (in fact, disabled in some ways) in Kubuntu. That's why you are probably getting some errors. In order to launch GUI apps with root privileges from the terminal, you have to use kdesu. For example

    Code:
    kdesu kursader

          You're still trying to run it from the root account...which can't access the X-server.
          use 'kdesu konqueror' from your user account (not root)
