I would never usually suggest any of the things in this post, but if
you're really stuck with Poulsbo hardware, you essentially have zero
good choices, so it's just a case of which bad choice you want to make.
Note that several years ago there was a proprietary driver which, while
in many ways being a pile of crap, more or less worked and gave 2D, 3D
and video playback acceleration.
Whoever was maintaining it gave up years ago, and you have 0 chance of
getting it to work on any modern distro, but you may be able to use it
if you run an old LTS build of Ubuntu. Ubuntu 10.04 should be old enough
for the proprietary driver to work, and still has support until mid-2015
according to https://wiki.ubuntu.com/LTS . Of course, the rest of the
environment will be from the middle of 2010. You could run an equally
old build of any other distribution too, of course, but few will have
any support at this point, and you'll likely be able to find old
guide/howto threads for running the GMA500 proprietary drivers on Ubuntu
more easily than any other distro.
If you want to go this route, the best thing to do is probably to start
Googling or searching the Ubuntu forums (where
Poulsbo-proprietary-driver-folk-wisdom tends to reside) with the magic
AFAIK none of the two or three different proprietary drivers put out by
different groups at Intel (yes...really) for the Poulsbo has been
maintained at all since 2011 or so, and you have no effective chance of
getting any of them working on distros with Xorg 1.10 or newer and/or
kernel 3.0 or newer. For anything modern you're stuck with vesa or the
gma500_gfx kernel driver and xorg-x11-drv-modesetting, which will be
barely any better than vesa, and both of which will be extremely
