Hello Mario, or anyone else affected,

Accepted ubuntu-drivers-common into trusty-proposed. The package will

-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.

Bug description:
  [Impact] 
   * Upon upgrading to Ubuntu 14.04 from an earlier LTS release the user's xorg.conf is renamed.  Any custom settings they've made will be removed.

   * Specifically for Mythbuntu 12.04 LTS users with NVIDIA graphics,
  they have a custom DPI setting that gets removed upon upgrade to
  14.04.

   * This has been fixed in utopic by testing if it's the first time
  that ubuntu-drivers has ran.  If so, it sets a first boot flag so that
  no settings are removed.

  [Test Case]

   * This can be reproduced by installing a 12.04 based release,
  creating an xorg.conf and upgrading to 14.04.  If the xorg.conf is
  renamed then the bug is hit.

   * This can also be reproduced directly on 14.04 by removing /var/lib
  /ubuntu-drivers-common/last_gfx_boot, creating an xorg.conf and
  rebooting.  This would simulate the same behavior.

  [Regression Potential]

   * Part of the intention of ubuntu-drivers-common is to prevent
  problems on people who have upgraded and now have hybrid graphics
  supported cards.  This won't make their situation any worse than
  previously it would have been before ubuntu-driver-common existed.

   * Any functional users in the field should still remain functional.
  This only affects the first boot scenario.
