[gentoo-user] kwin opengl compositing w/ nouveau?

[Doug Hunley <doug.hunley@gmail.com>]

Me again ;)

I just ran 'startx' on my machine for the first time in a dog's age
and had to switch the rendering engine to XRender from OpenGL to get a
usable desktop (couldn't see the desktop. was a bunch of black
squares). I'm not sure what changed, and the online wiki/forum  pages
I just spent two hours reading were stale and of little help. Anyone
see anything stupid herein:
-- make.conf --
VIDEO_CARDS="nouveau"

-- eselect --

At this point, I don't care if it's OpenGL or OpenGL ES (kwin_gles)
that we get working.. I just want to use something 'better' than
XRender again (it lags badly for me)

Thanks!
