[Bug 1525509] Re: regression on 4.3.x: i945/Display corruption (before X, X never starts))
While I can't claim any authority on the subject I don't think bug
#1522922 is a duplicate because this bug is a regression starting from
4.3 without any mentioning of Displaylink.
There are similar reports for Fedora
(https://bugzilla.redhat.com/show_bug.cgi?id=1298878), Debian
(http://bugs.debian.org/808916) and upstream
(https://bugs.freedesktop.org/show_bug.cgi?id=92718).
If you're experiencing the problem can you please check if upgrading the
kernel to 4.4 helps?

Title:
regression on 4.3.x: i945/Display corruption (before X, X never
starts))
Status in linux package in Ubuntu:
Incomplete
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:
