"In release 2.0.6, when Linux evdev keyboard support has been moved to a separate source file, a feature was added to disable normal keyboard event processing to prevent "spilling" keystrokes to background virtual console. This feature has one unpleasant side effect: if application fails to call `SDL_Exit` before termination or crashes with fatal signal, console is left in unusable state with keyboard not working and no possibility to switch virtual console. If user has a chance, he can login remotely and restore keyboard with `kbd_mode`, otherwise the only option is to reboot the machine. This patch fixes that problem by intercepting fatal signals (with `sigaction`) and process termination (with `atexit`), to restore keyboard state, if it wasn't properly restored with `SDL_Exit`. The function registered with `atexit` also restores original signal handlers, to prevent leaving invalid handlers after SDL library is unloaded, if it was loaded dynamically with `dlopen`. No signal handlers or `atexit` function are installed if SDL boolean hint `SDL_HINT_NO_SIGNAL_HANDLERS` is `SDL_TRUE`. Additionally, if environment variable `SDL_INPUT_LINUX_KEEP_KBD` exists, keyboard initialization function completely skips disabling keyboard. This can be useful for debugging." Fixes Bugzilla #4193. |
