As for the two models, 4174-A11 and 4174-AY9, I haven't been able to find any differences whatsoever between the two. (In fact, Lenovo tells me that the hardware in them should be identical.)
The 4174-A11 I have behaves a little differently in that sometimes when X starts, it thinks that VGA is connected (it isn't) and sets the display to 1024x768 in mirroring mode. But even when this doesn't happen and it boots without VGA and running at native 1600x900, there's no corruption on the A11 model. The A11 is running the same BIOS as the AY9 (1.09 before, and new freshly upgraded to 1.25). But I only have one A11, so it possible that it's a fluke that it works correctly. I have a whole pile of AY9s, and they all exhibit the corrupted display behavior. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/812638 Title: video problems with Thinkpad T420s integrated intel graphics To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-backport-natty/+bug/812638/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
