Public bug reported:

BUG: Invisible Cursor with Ubuntu 19.10 Desktop Upgrade and Install CD
Boot

This bug was reported here:
https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1851340

WHAT OCCURRED:


Upgrade from Ubuntu 19.04 to 19.10 results in having invisible cursor on main 
Gnome Desktop

Subsequent testing revealed that issues is able to be demonstrated by
just booting from Live iso image

B) Attempt Fresh 19.10 Desktop Install

B.1) Boot - Ubuntu 19.10 Desktop CD-ROM image via USB - Mouse / Cursor
not visible

So I have unable to proceed with clean 19.10 install as there was no
mouse cursor visible.

WHAT WAS EXPECTD:

Gnome Desktop with working cursor

POSSIBLE ROOT CAUSE:

Investigation has identified pull request for 5.3 Kernel that includes
fix for cursor issue with MatroX Graphics:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=574cc4539762561d96b456dbc0544d8898bd4c6e

See:

 mgag200:
   - cursor support fix


So issue possibly resolved with kernel update, as have two cases reported with 
Matrox G200 embedd graphics controllers.

Raising here so that can be verified and tested by Ubuntu Kernel team.
