Is it possible to replace the I-beam cursor system wide through X or Wayland (trying to think ahead here)? In explanation, years ago I suggested (to deafening silence), that Open Office offer a block/blinking block or underscore/blinking underscore cursor. However, I'd prefer no I-beam cursor in any application (browser, spreadsheet, email ... you name it). If I understand correctly, X displays what the application directs. Would it be possible to amend X to display a different cursor anytime it's directed by the application to display the I-beam?
