SUMMARY STEPS TO REPRODUCE 1. Install ubuntu software preferences (gtk) 2. Launch Ubuntu software preferences -> drivers and KCM driver manager 3. Ubuntu software prefs will display some drivers within about five seconds. KCM will never display anything. Is this a kubuntu bug?
We don't have a driver manager, so it must be something downstream. Please try to find out where it's from and report there If unsure upload a screenshot and reopen and I'll ask people
