Re: Can't enable XGL
I disabled 3D, uninstalled compiz and emerald then logged out/in. Re-downloaded compiz then enabled XGL. As before, I could not log in.
When I changed the setting back to what I was using before (native support), I could log back into KDE4 as normal. And all the 3D effects were as normal (minus the emerald stuff obviously).
I do not know of any xgl.log existing, there is none in /var/log/ directory.
