[Bug 1777257] [NEW] Dell Inspiron 17r 5737 Ubuntu 18.04 Video Looks Very Strange

[Merlin]

Public bug reported:

When booting 18.04 on my Dell 5737 I am greeted with an image like the
attached. The colours are clearly incorrect and the display looks to be
of low resolution. This is true whether booting from a fresh
distribution copy on a memory stick or the subsequent patched install.
The image on an external monitor appears unaffected.

This looks like a reappearance of

to have the same issue on a similar machine:

installing-18-04-on-dell-inspiron-3737/1047143#1047143

Adding "nomodeset" does make the machine usable but obviously isn't
ideal.

"lsb_release -rd" gives Ubuntu 18.04 LTS release 18.04.
