Still other way is to change the "cvvis" capability to send the
"\E[?25h\E[?0c" command.
*** GNU/Linux: GPM mouse does not display but still otherwise works.
This happens on Linux kernel versions from 6.7 to 6.13. On these
versions, the Linux kernel does not allow programs to draw the mouse
pointer unless they have superuser permissions. The GPM daemon
normally has such permissions and it draws the mouse pointer for other
programs such as your shell and many ncurses based programs, but not
for Emacs.
To solve this, you need to change your kernel to a version with this bug
fixed, such as 6.14. See associated Linux kernel fix:
