Hi, Efraim Flashner writes: > This increases the size of 'guix size sdl' from 491.1MiB to 491.2. Do we > need anything similar for sdl2? I tried to fix sdl2. Do you mean ‘sdl’? I tried to run tuxpaint which was build from our Guix package collection and sdl version 1. The cursor is black, so I cannot say is it broken or not. Also I checked other ‘sdl’ games, but no custom cursor there, too: meritous, knights, prboom-plus, lierolibre, chromium-bsu, tuxpaint, kobodeluxe, enigma. NIX's SDL package doesn't contain libXcursor input, but SDL2 does contain. I think we should follow this decision. I worry about qemu and other sdl2 dependent packages. Should the patch be merged to core-updates? Marius Bakke writes: > Woow, nice find.

I'll add “Enable X11 cursor support in dependent programs” above ‘("libxcursor" ,libxcursor)’. Also I'll place the libxcursor to ‘inputs’ instead of ‘propagated-inputs’ of SDL2 package, because it's enough as I tested.
