Public bug reported:
This affects both Ubuntu GNOME and Ubuntu Wily 20151017.1. The graphics
are so badly garbled I can only file this bug on an unaffected OS where
I've held back the update on just that one package to about Alpha 2
status:
lance@lance-INTEL-desktop:~$ apt-cache policy xserver-xorg-video-intel
xserver-xorg-video-intel:
Installed: 2:2.99.917-1ubuntu1
Candidate: 2:2.99.917+git20150808-0ubuntu4

I'll attach a picture of the garbled screen with the updated xserver-
xorg-video-intel package. Oddly a screenshot taken from the affected OS
displays perfectly OK in the unaffected OS so I used my camera.
The info provided by lspci may not be very helpful:
lance@lance-INTEL-desktop:~$ lspci -v -s `lspci | awk '/VGA/{print $1}'`

The tech specs show:
Internal Graphics:
• Intel ® GMA4500 onboard graphics subsystem with support for:
― Analog displays (VGA)
― Digital displays (DVI-D)
I'm just using VGA ATM.
Something else worth mentioning is this warning displayed while filing
the bug report:
Your system is providing 3D via software rendering rather than hardware
rendering. This is a compatibility mode which should display 3D
graphics properly but the performance may be very poor. If the problem
you're reporting is related to graphics performance, your real question
may be why X didn't use hardware acceleration for your system.
I did try booting an earlier kernel to no avail, but holding back just
this one update prevents the borkage.
