 Still other way is to change the "cvvis" capability to send the

+*** 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:
