They are using grub2 now. It reads from several files now (one of which
probes for operating systems) when generating the config. These are
sourced from /etc/grub.d/ . I have not sat down to really learn the
ins-and-outs of configuring the new grub yet, aside from turning on the
highres boot prompt in /etc/default/grub.

From /etc/grub.d/README:

"""
All executable files in this directory are processed in shell expansion
order.

  00_*: Reserved for 00_header.
  10_*: Native boot entries.
  20_*: Third party apps (e.g. memtest86+).

The number namespace in-between is configurable by system installer
and/or
administrator.  For example, you can add an entry to boot another OS as 
01_otheros, 11_otheros, etc, depending on the position you want it to
occupy in
the menu; and then adjust the default setting via /etc/default/grub

I may pull out an old monitor to try on my desktop. I know I've had
issues attaching an external display to my intel-based laptop, but I
think that is a probing issue with my KVM.

If you're using the nouveau or nv driver, this is a bug. If you're using
the nvidia binary driver, I think they still want you to use their
nvidia-settings utility and xorg.conf.

Ubuntu has been using pulse for several releases now. I haven't noticed
any issues switching between applications.

What I have noticed is that audio hardware is powered down when idle.
This should save a bit more power on laptops, etc. Unfortunately,
certain audio hardware pops when powered back up. I seem to recall
somebody seeing if there was a way to stop it, but I think it comes down
to the components used and/or design of the audio device. My intel hda
audio on my laptop pops, albeit quietly. Apparently some other intel
cards do not.
