I get a scrambled screen (four blurry miniaturized version of the same display) when I boot in EFI mode (EFI stub).

I can provide further debug information if needed.
Comment 5 Bastien Dejean 2012-12-20 18:03:10 UTC
I'm still willing to help.
Comment 6 Alex Deucher 2012-12-20 18:20:05 UTC
Are you using gfxpayload=keep in your grub config?  If so does it help if you remove it?  Can you also try a 3.8 kernel?  Specifically this patch:

Comment 7 Bastien Dejean 2012-12-20 19:42:29 UTC
I don't use grub (I boot through rEFIt thanks to EFISTUB).

I'll try 3.8 ASAP.

Thanks.
Comment 8 Bastien Dejean 2012-12-20 19:44:02 UTC
Sorry, I meant rEFInd.
Comment 9 Bastien Dejean 2013-03-23 09:44:53 UTC
Tried 3.8.4: no improvements.
Comment 10 Alex Deucher 2013-03-25 14:12:29 UTC
Does it work ok with grub?
