*another* possible way if you can live without beryl XD will be
* write beryl-manager -d
------ I dont know what mean "-d"
* hit 4 times the down key, 1 time right key and see your menu for memorize how to load metacity or kwin XD.
I know it is not fix beryl... but I suppose it should work instead of try to hit the correct menus in a black screen!!!!!
Actually will be interesting if some 1 know how to do the same that with the menu, but with a direct command...
Also what about
: with ALT+F2??? (the following will work?? or it only blow it down!!!) (you should check it out... this are only ways that I suppose perhaps work, but havent tested the myself, they are only options that show when I try to call in a console metacity).
