Public bug reported:
I added:
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "uxa"
EndSection
to /etc/X11/xorg.conf and restarted lightdm which seems to have given me
some hardware acceleration. It still isn't the same as what the laptop
performs like running Windows 8 however it does make ubuntu usable
again. the laptop is an Acer Aspire S3-391-32364G52add
