I would consider having a look at bug 43655, it might be related. Could you try workaround proposed in comment 8 (bug 43655#c8) or comment 13 (bug 43655#c13)? I am not using grub2, so I do not believe that the workaround in BUG 43655 are relevant. I do not have these lines in my grub.conf Created attachment 64758 [details] [review] Cleanup and fix mc programing This patch should fix your issue I do not see any improvement after applying the proposed patch Maybe I have the same problem. Tested on ubuntu 13.04 and 13.10， my new HD6450 just gives me the same corrupted screen as yours. On windows, it works with no problem.

I believe kernel-3.8 and 3.11 already have these patches, but it looks like doesn't work. (In reply to comment #5) > I would consider having a look at bug 43655, it might be related.
