It appears on the first console (Ctrl-Alt-F1) where I run the SDL program.

I tried setting environment variables SDL_MOUSEDEV=/dev/mouse and
SDL_NOMOUSE=1, but neither worked,
no images appears.
I have attached the respective strace. With SDL_NOMOUSE=1 it never
returns, then because of size I edited the strace file and I added
comments with "//" to indicate the repeated lines.

In the strace file attached at original email, I interrupted it (ctrl-c)

Yes, I'm running it as root
