Just as the title says, I can no longer select shutdown or reboot from the menu. The most recent thing to happen is my desktop crashed while exiting a fullscreen video in steam (I'm reasonably sure it uses chromium as a backend) leaving my apps open but the menu bars and anything desktop related were gone. I opened the terminal with Ctrl + Alt + T and used sudo reboot. Now my menu won't show shutdown or reboot. Anyway to jump start it?
