[Bug 889226] Re: X fails to correctly find my USB input devices

[Steve Langasek]

Setting up udev (175-0ubuntu1) ...
Installing new version of config file /etc/init/udev.conf ...
restart: Job failed to restart

The problem is that udev is calling 'restart udev || true'.

- restart is the wrong interface.  This needs to be using invoke-rc.d instead.
- ignoring the return value is wrong.
- the restart is failing because restart is the wrong interface, with the wrong semantics - 'restart' causes the process to be kill -HUP'ed and respawned via the existing job configuration, *not* using the one from the just-upgraded package.  And there are crucial differences in the job file here, because udevd has moved on disk.  So of course trying to restart 'udevd' will fail, it needs to start up /lib/udev/udevd instead.

This will consistently cause udev to fail to restart for all users when
upgrading to precise, leading to difficult-to-diagnose bugs.  Should get
fixed for alpha-1.

  X fails to correctly find my USB input devices

Bug description:
  For some reason, when I plug my USB kvm into my laptop today, X fails
  to register the attached input devices (keyboard and mouse).  The
  devices are correctly registered in the kernel, but X somehow gets the
  wrong device name for them: it's looking for non-existent event13 and
  event14, when the correct devices are event9 and event10.

  I'll attach the Xorg log separately, since this is all happening on :1
  instead of :0 (due to an unrelated bug).
