Title:
  [xorg-edgers] Held broken packages (libgbm1) from Xorg-edgers PPA

Status in xorg package in Ubuntu:
  Confirmed

Bug description:
  My laptop (Aspire VN7-591G) comes with an nVidia graphic card that is
  not supported by default in Ubuntu Trusty (14.04.2, amd64).

  I installed the Xorg-edgers PPA to be able to install nvidia-340 which
  contains the proper drivers for my card (and allow me to switch
  between the Intel and the nVidia GPU).

  Later, I realized there is a dependency issue with package libgbm1:

  sudo apt-get dist-upgrade
  Reading package lists... Done
  Building dependency tree       
  Reading state information... Done
  Calculating upgrade... Done
  The following packages have been kept back:
    libgbm1
  0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.

  Using aptitude to have more information, I get this:

  --\ Packages being automatically held in their current state (1)
  i A  libgbm1                                                                                            10.1.3-0ubuntu 10.6.0~git2015

  libgbm1 will not be upgraded to version 10.6.0~git20150310.5750595c-0ubuntu0ricotz3~trusty, to avoid breaking the following dependencies:
    * libgbm1 replaces libgbm1:i386 (< 10.1.3-0ubuntu0.3)

  It appears that this package is used by the xorg-edgers PPA:

  % apt-cache policy libgbm1
  libgbm1:
    Installed: 10.1.3-0ubuntu0.3
    Candidate: 10.6.0~git20150310.5750595c-0ubuntu0ricotz3~trusty

       10.1.0-4ubuntu5 0
          500 http://archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages

  I tried to force-install package libgbm1 but get the following error:

  sudo apt-get install libgbm1
  Reading package lists... Done

  Reading state information... Done
  Some packages could not be installed. This may mean that you have
  requested an impossible situation or if you are using the unstable
  distribution that some required packages have not yet been created
  or been moved out of Incoming.
  The following information may help to resolve the situation:

  The following packages have unmet dependencies:
   libgbm1 : Depends: libgl1-mesa-dri (= 10.6.0~git20150310.5750595c-0ubuntu0ricotz3~trusty)
  E: Unable to correct problems, you have held broken packages.

  What can I do to fix this?

  Thanks in advance!

  
  P.S.: This issue was reported on askubuntu [1] but I didn't get any feedback.
