Shutdown beryl during hybernation

[niccoswe]

Hi i'm pretty new to using linux. I really enjoy using beryl (also beeing an mac-user, i find the scale effect usefull). The thing is that i can't get firefox or opera to function properly after i hibernate with beryl running. When i get back from hibernation, it'll work for a while, but after some time, it will just freeze the computer (allways happens while i'm using the browser) - i can't even move the mouse pointer . I have managed to figure out a (kind of rough) workaround for this problem. If i shut down beryl and use metacity before i hibernate, then restart beryl when get back up, opera will work just fine.

The question is: How can i do this automatically at hybernation?
