I recently started using Awesome (the X windows manager) in my Ubuntu. It is awesome! But some times (once a day max) it kinda crashes — or at least stop accepting shortcuts input. I get stuck on the workspace (tag, I belive they call it) I am. Clicking on the other ones, or using Mod4+numbers won't work. It simply stops listening. If I type mod4+j, it types
j, as if only the awesome's keylistener had aborted or something. But everything runs fine in the current workspace, the awesome UI still render on the top, and even the clock keeps ticking!
The only thing left to do is to manually shut down the machine, as I can't even turn it off properly... I have no idea what is going on. It might as well be a shortcut to disable all shortcuts or something that I eventually accidentally type, or a weird semi-crash, but I've searched Google a lot for references and found nothing. Does anyone have a clue on what happens and how to fix it (or better yet, prevent from happening)?
