[Bug 1367241] Re: Incorrect udev-fallback-graphics.conf

[Martin Pitt]

Utopic fix committed to git, thanks! I keep this open for trusty, but as
it's neither a data loss nor critical bug and just a cosmetical corner
case I keep it as low importance.

You say "since 3.13.0-16.36" which is trusty -- i. e. precise's kernel
still has it as a module? So it seems to me that this doesn't affect
precise at all. But even if it would, if such a cosmetical bug hasn't
caused trouble in 2.5 years, it's certainly going to be fine for the
other 1.5 years.

Bug description:
  [Impact]

   * When setting up primary display driver fails an attempt to load vesafb
     module is undertaken. This fails since from 3.13.0-16.36 version
     vesafb is compiled in the kernel (so no actual modprobing is needed).
     This causes false alert in the log:
     "Starting load fallback graphic devices: [fail]"

  [Test Case]

   * Start Ubuntu unable to load primary graphics driver (the simplest way is to remove module responsible for the device).
   * Wait for loading graphics devices.
   * If the primary device module has failed to load, falling back to vesafb will be attempted.

  [Regression Potential]

   * Implemented by the bug reported.

   * Affects only the debian/ directory.

  [Other Info]
   
   * Original bug description:

  The udev-fallback-graphics.conf script tries to load vesafb module if
  PRIMARY_DEVICE_FOR_DISPLAY has not been set earlier.

  The problem is that from kernel version 3.13.0-16.36 vesafb is
  compiled in permanently into the kernel (CONFIG_FB_VESA=y), so
  whenever the fallback mode is triggered this script will FAIL
  confusing the users.

  Most probably this file is no longer needed (or it just be used to
  print informative message).
