[Bug 1525509] Re: regression on 4.3.x: i945/Display corruption (before X, X never starts))
The 4.4.0-999-generic daily (201512120150) seems to work.
Although there's a whole bunch of slowpath warnings in the logs.
(I say seems to work - I'm running it now in KDE apparently OK; on the first boot the desktop didn't complete starting up but ti wasn't obvious why, X was still responsive just apps didn't start; but that seems different?)
Here's the current boot warnings in the working 4.4:

Title:
regression on 4.3.x: i945/Display corruption (before X, X never
starts))
Status in linux package in Ubuntu:
Confirmed
Bug description:
This laptop works with 4.2.0-19 and fails with 4.3.0-2.
At boot (before X) the display is corrupt - with the entire screen
shifted halfway across the screen with the kernel boot text mostly
readable, just shifted over (and some crud at the top). X doesn't
start. Returning to 4.2.0-19 (as now) and it's fine.
In the 4.3.0-2 world I see the following warning in the dmesg:
