Just bought 3 intel boards with Ivy Bridge i3 3220t processors. Integrated graphics. When I run LM13 Mate Live CD, or if I install it, the monitor has serious corruption. Lot's of blocky things, blank spaces, half of wrods showing...
I can run a Live CD of LM9 & all looks normal. Not sure if this is just Mate, or if it affects Cinnamon as well.
I'm displaying on an LCD through teh DVI port. When I check for proprietary drivers their aren't any.
Edit - Found it. It's a bug which is fixed by loading:
This was actually already on the system but updating it fixed the problem.
