thanks very much!

I have tried what you tell me:

1. I input "  eval 'dbus-launch --auto-syntax'  " in Super terminal,  it output "-sh: eval: line 1: dbus-launch: not found";

2. I input "  eval './dbus-launch --auto-syntax'  " in Super terminal,  it output "DBUS_SESSION_BUS_ADDRESS='unix:abstract=/tmp/

3. I input "./car -qws &", the car show in my touch panel.

4. I input "./controller -qws", the controller show in the touch panel, but it still show "disconnect".

It must be something wrong in my operation, could you tell me?

thanks again for your reply and i'm Looking forward to your reply!

PS: if I request the DBUS session bus be run when my application run, what should i do in my program?

Best Regards!

The proper way to start the D-Bus session bus is:

	eval `dbus-launch --auto-syntax`
