kubuntu-driver-managers leaves apt in a broken state when switching drivers on a nvidia machine

[Rohan Garg]

[Impact]
When switching drivers on a nvidia machine, kubuntu-driver-manager screws up apt post driver install since it removes xserver-xorg-video-nouveau.

[Test Case]

* run driver manage via: alt+f2 -> kcmshell4 driver_manager
* change driver to nvidia
* try and install something via apt-get
* apt-get complains
* update to package from proposed
* change driver to nvidia
* try to install something via apt-get
* apt-get should not complain

[Regression Potential]

None

[Other Info]

Hello Rohan, or anyone else affected,

Accepted into trusty-proposed. The package will build now and be available in a few hours in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

I can confirm I can install applications from muon and from the command line just fine after this update

  * DriverWidget: do not list builtin drivers as not selected.
    + This avoids breaking the system by trying to remove essential packages
      such as xserver-xorg-video-nouveau for being not selected.
    LP: #1311583

  [ Rohan Garg ]
  * Add a apport hook to provide more debug info when reporting bugs

kubuntu-driver-manager (14.04ubuntu8) trusty; urgency=medium

  * Prevent crashes by properly locking the GUI while applying changes
    LP: #1311075
    + New function DriverWidget::setSelectionEnabled, disabling or enabling
      all QAbstractButtons inside the respective DriverWidget, leaving the
      header label unaffected to give a nicer visual experience.
  * Prevent state confusion caused by allowing 'defaults' to trigger a reload
    even when the manager is currently busy applying changes. Since we have
    no button control inside the KCM we simply turn load() noop while the
    manager is active. This is unfortunately not the nicest behavior, however
    the module will reload whenever the manager finishes, so implicitly we
    will simply execute the requested action once the manager is idle again.
    LP: #1311079
    + Introduce new function DriverManager::isActive evaluating the transaction
      pointer (nullptr when idle).
