Hi, I spent a while debugging why I cannot switch back to SDL window from which I've switched away, and noticed that it's actually easy to fix. Application switcher needs to know which window matches to which .desktop file. This is done using the standard WM_CLASS X property. So, e.g. to be able to switch back to the Bomberman game, you need to... Add following line to Bomberman .desktop file for application switcher: StartupWMClass=Bomberman And ask SDL to use that WM_CLASS definition for the Bomberman game window through an environment variable by adding following line to the "launch-bomberman" script: export SDL_VIDEO_X11_WMCLASS=Bomberman I.e. only two lines need to be added and no actual code needs to be changed! - Eero
