Does someone (Jared?) have a system with a gpm-mouse build and can
reproduce and debug this, please?

Remind us what this needs? A real linux console, ie not an xterm?

Yes, GPM is for linux virtual consoles.

It requires both a Linux kernel with GPM support as well as an Emacs build with GPM enabled
  

  
I have tested GPM under a VM in the past. I can bring it up and check the state of things.

I tested this locally at HEAD (b5845e) on Linux debian 6.1.0-13-amd64 
and everything is working fine.

Could you please describe what terminal (the output of "echo $TERM") and 
kernel version (the output of "uname -a") you are using when you have 
this issue? Can you try toggling M-x gpm-mouse-mode on and off and share 
if any errors are reported?

I can reproduce the issue in the Linux terminal (echo $TERM => linux,
uname -a => Linux strobelfssd 6.10.6 #1 SMP PREEMPT_DYNAMIC Mon Aug 19
12:15:23 CEST 2024 x86_64 GNU/Linux).  When I start emacs there with -Q,
`C-h v gpm-mouse-mode' says the value is t and I see the blinking cursor
in the emacs window, but moving the mouse I see no gpm cursor, though I
can make and yank selections and pull down menus in Emacs with the mouse
(the blinking cursor is not moved by the mouse).  When I type `M-x
gpm-mouse-mode' there are no errors and a cursor appears that moves with
the mouse (the blinking cursor remains visible and unresponsive to the
mouse), though `C-h v gpm-mouse-mode' now says the value is nil; I can
make selections as before (though the highlighting is a different color
than before) but I cannot pull down menus with the mouse.  This is with
emacs-29, emacs-30 and master.

Thank you, I am able to reproduce the issue locally on "Linux debian 
6.11.5+bpo-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.11.5-1~bpo12+1 
(2024-11-11) x86_64 GNU=Linux". I will investigate.
