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? ** Bug watch added: Red Hat Bugzilla #1298878 https://bugzilla.redhat.com/show_bug.cgi?id=1298878 ** Bug watch added: Debian Bug tracker #808916 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=808916 ** Bug watch added: freedesktop.org Bugzilla #92718 https://bugs.freedesktop.org/show_bug.cgi?id=92718 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1525509 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.

[Kernel-packages] [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?)
