Hello,
I am trying to turn on some effects in Desktop effects and I get this error:


Using propietary AMD drivers, ubuntu version 12.10. How can i fix that? Is some packages missing or what?

hi,

visit advanced tab and check "use opengl 2".

Depending on the driver (fglrx) and version that won't be possible.
You'll have to use:

KWIN_DIRECT_GL=1 LIBGL_ALWAYS_INDIRECT=0 KWIN_COMPOSE=O2 kwin --replace &

(that's O2 like OpenGL 2) but be aware that overriding the system detection may result in crashy behavior.

On a sidenote: the explosion effect is yet unmaintained and pretty much broken anyway.
