I'm using SDL to display images on a monitor, without X installed.
When my program ends successfully, the monitor goes back to the login prompt (as expected). But when my program crashes, the last image stays frozen on the monitor (even if I launch the program again, the last image of the previous execution stays stuck on the monitor).
How could I kill the display in order to "use" it again ? The only solution that I found is to reboot the computer but I need to avoid that because other processes run on the computer and cannot be interrupted.
