Now, NO Window Decorations on Nvidia Legacy 304xx

[David Baron]

KDE applications did get them.
Now, nothing gets them.

Please, kwin maintainers: Since I can get the decorations by toggling 
compositors, the graphics driver can display them. There should be some fix 
possible. I am unsuccessful trying to downgrade 304xx packages.

Would be nice to have Nouveau back and get off proprietory stuff, but that is 
another issue.
