Actually - nvidia-prime seems less likely now that I read gpu-manager
code.  It's a "new" tool for upgrades, and consequently would run it's
enable_nvidia routine the first boot.

It checks how many cards are in the system, and if it only finds 1,
removes the old xorg.conf without making a new one.


    /* See if enabling the driver failed */
    if (status) {
        /* If xorg.conf exists, make sure it contains
         * the right BusId and NO NOUVEAU or FGLRX. If it doesn't, create a
         * xorg.conf from scratch */
        if (!check_vendor_bus_id_xorg_conf(devices, cards_n,
                                           vendor_id, "nvidia")) {
            fprintf(log_handle, "Check failed\n");

            /* Remove xorg.conf */
            remove_xorg_conf();

            /* Only useful if more than one card is available */
            if (cards_n > 1) {
                /* Write xorg.conf */
                write_to_xorg_conf(devices, cards_n, vendor_id);
            }
        }
        else {
            fprintf(log_handle, "No need to modify xorg.conf. Path: %s\n", xorg_conf_file);
        }
    }

Title:
  DPI really messed up after upgrade

Status in Mythbuntu, Ubuntu derivative focused upon MythTV:
  Confirmed
Status in “ubuntu-drivers-common” package in Ubuntu:
  New
Status in “ubuntu-release-upgrader” package in Ubuntu:
  Confirmed

Bug description:
  Mythbuntu installs with an NVIDIA graphics card generally have a
  modified xorg.conf that sets the DPI to 100x100 so that it looks
  correct on a Television set.

  Upgrading from 12.04 to 14.04 the xorg.conf was renamed and the
  display did not look correct at all.

  This is the xorg.conf that was on the system

  Section "Screen"
  	Identifier	"Default Screen"
  	DefaultDepth	24
  EndSection

  Section "Device"
  	Identifier	"Default Device"
  	Driver	"nvidia"
  	Option	"DPI"	"100x100"
  	Option	"NoLogo"	"1"
  EndSection

  Section "Extensions"
  	Option "Composite" "Disable"
  EndSection

  
  After upgrade it was renamed from /etc/X11/xorg.conf to /etc/X11/xorg.conf.04142014

  Renaming it back fixed the problem.
