* prime-xconfig:
  - Format the BusID string correctly (LP: #1282796).
    The BusID string created by prime-xconfig had several problems:
    1) It was missing the bus type "PCI", as recommended by
       xorg.conf(5).
    2) Values were written in hexadecimal, as reported by lspci,
       instead of decimal, as expected by the server. (See the
       comment at the top of xf86ParsePciBusString().)
    3) The PCI domain was not specified.
    Giving the BusID string in the wrong format could cause the X
    server to fail to parse the BusID, or to parse numbers in the
    wrong base. On systems with more than one PCI domain, `lspci -n`
    output would include the domain number, which is omitted by
    default on systems with only one PCI domain. nv_get_id()
    expects the bus number to be the first field, which would not be
    correct when `lspci -n` reports the domain, as it does on
    systems with multiple domains.
    Fix these issues by always reporting the domain with `lspci -Dn`
    and using it in the BusID string, prepending "PCI:" to the
    BusID string, and printing all numeric values in decimal.

* debian/control:
  - Add alternative dependency on gdm and kdm.
* debian/preinst.in:
  - Set the lightdm configuration bits only if lightdm is the
    default display manager (LP: #1262068).
* debian/postrm.in, debian/rules:
  - Avoid calling dpkg-architecture (LP: #1264611).
* prime-xconfig:
  - Format hexadecimal parameters properly (LP: #1252667).

* New upstream release:
  - Add support for power management (LP: #1259237).
* debian/control:
  - Depend on upstart, bbswitch, lsb-release, lightdm >= 1.2.3-0ubuntu2.4,
    screen-resolution-extra (>= 0.14ubuntu2.1).
  - Build only for i386 and amd64.

* debian/preinst.in:
  - Remove leftover in the test condition. This was
    causing the lightdm.conf file to be rewritten
    every time. This is a serious problem on the
    different Ubuntu flavours (LP: #1224098).
* debian/postinst.in:
  - Apparently the printf command treats string values
    with leading zeros as octal. Work around this by
    removing any leading zeros (LP: #1219650).
