Title:
second, dead, mouse pointer left on screen after login, x11 session
Status in mutter package in Ubuntu:
Confirmed
Bug description:
This seems to have become repeatable, and applies even on the first
login session immediately after booting the computer. I don't know if
this is the right package to report against; another possible culprit:
gdm:
When I log into the default "Ubuntu" session (ie: on xorg), gdm's
mouse pointer remains on screen during the screen blank, and after the
gnome desktop comes up. It stays on the top just like you'd expect of
the mouse pointer, but it's immobile and unresponsive. It's left at
the same position on the screen that it was while using gdm, and is
the same size as it was in gdm (ie: gdm is not scaled, but gnome
session desktop scaled to 150% - the *working* in-session mouse
pointer is also 150% larger than gdm's dead one).
It looks like gdm and gnome are running in the same x11 session?
Seeing as the mouse pointer stays solid *during* the transition from
gdm into the gnome desktop. Not even a flicker. It's almost as if
we're trying to have smooth transitions for these sorts of things,
which is good of course, but maybe is a bug in that?
It disappears when I log into a Wayland session, it appears only to
affect x11 sessions.
I've taken to just moving the mouse pointer to the far bottom right
corner of the screen before logging in, so at least it's not very
intrusive.
There are a few reports of similar in askubuntu from a few years back,
but with no helpful or applicable solution. eg:

To answer the points made there, the xinput --list output is shown
below. Executing that command and rebooting makes no difference. In
the Displays Prefs there is no second "Unknown" display to disable.
(The machine has precisely one display, and that's all Settings sees.
It's a desktop, not a laptop, and it only has an AMD Vega integrated
graphics. It also has only one mouse.)

I thought of a couple of things to try after starting to write this
ticket but didn't want to lose the ticket in progress, so will add
comments if they show up anything. In particular, I am running the
experimental feature to enable xrandr fractional scaling. This issue
didn't show up right after enabling that, only a couple of days later,
so it didn't seem immediately relevant.
Also, trying with a different pointing device attached in case that
transceiver is doing something odd. (never had problems before, had it
years, no idea if that doubling-up has always been there.)
