Can't take screenshots in fullscreen app

[EpsilonDelta]

Hi all, I'm writing a game in c++/sdl. At first I couldn't get fullscreen to work properly, but I fixed that by disabling "Unredirect Fullscreen Windows" in CompizConfig.
However, none of the hotkeys for minimize/screenshot etc. appear to be working now. Is there any way to make fullscreen screenshots?

No, all normal hotkeys are disabled when in fullscreen mode. I can't even alt-tab to a terminal. Perhaps unredirect fullscreen windows should be turned on, but then the gnome panels stay on top over my fullscreen app, and they will be in the screenshot.

No, all normal hotkeys are disabled when in fullscreen mode.
Even the PrtSc button?

Yes. PrtScn, alt-f4, none of the normal hotkeys is working while in fullscreen. So I can't go to a terminal or take a screenshot. Note that this is only after I disabled "unredirect fullscreen windows" in CompizConfig -> general settings. But before disabling that, the gnome panels would stay on top (over my fullscreen window) and flicker every once in a while. And If took a screenshot, the gnome panels would be in it.
Perhaps I'll just take the screenshots in Windows then... but there must be a way to do this in Ubuntu, right?

Did you ever find a way to take a screenshot in fullscreen apps? I'm suffering the same problem =(

Does hooking up one of the screenshot programs to my program here (http://ubuntuforums.org/showpost.php?p=2901208&postcount=7) get you any love?
