After upgrading to Kubuntu 15.04 (via 14.10) from 14.04, I started
having new issues with overheating. I have a Dell XPS 13 (Developer
edition) with Intel HD4000.

In particular it is now difficult to watch HD videos (e.g. from
Crunchyroll.com), whether through Firefox or Chrome. After a couple of
minutes, the CPU throttles hard as it gets too hot (verified with
sensors), making the video unwatchable. This is not an issue I observed
back when I was running 14.04.

After reading around, I installed the vdpau libraries, but that didn't
help. I then found this issue, and saw that vdpauinfo gave the same
error report.

I don't know that it is a very good workaround yet, but doing 
VDPAU_DRIVER=va_gl firefox
got me through the video I was watching without throttling (it still got relatively hot though).

The suggestion with the ppa above did not work as apt refused to use
that repo.

To me, due to the overheating, this seems to be a rather critical issue.

Bug description:
  This has been bothering me at least since precise (although there the
  missing link went to libvdpau_nvidia.so which was all the more
  mysterious since I do not own NVIDIA hardware).  In numerous cases do
  I get a warning that libvdpau_i965.so is being tried to be accessed
  but it fails.  I also can't find that file anywhere on my system or in
  the Ubuntu repository.  I tried poking around with ldd to find out
  where the call to that lib comes from but so far unsuccessful.

  $ vdpauinfo
  display: :0   screen: 0
  Failed to open VDPAU backend libvdpau_i965.so: cannot open shared object file: No such file or directory
  Error creating VDPAU device: 1

  libvdpau1:i386 is version 0.7-1 and vdpauinfo is 0.1-1
