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.
