What is your video card model ?

You should be able to reconfigure your xorg with this command:

sudo dpkg-reconfigure xserver-xorg

you can try to use mesa module if you are not sure ..

I had a similar issue a couple weeks ago. After a while I discovered that an additional hardware driver got auto activated after the update.

I solved it by simply DEACTIVATING all Additional Drivers.

This should be fairly secure since open source drivers will work.

To try it out do the following:

Gear menu > System Settings > Additional Drivers > THEN deactivate any active (green) driver that you find. They all should be deactivated (Gray) just like in the image below.
