Hi people, (on kde4.3 - compiled from source with nvidia drivers) My kde 4.3 env, has been working normally since I compiled it. I'm actually very satisfied. Much better than version 4.2. Unfortunately, I just restarted my laptop and, don't know why, the compositing functionality was turned off. I tried to turn it back on, (alt+shift+F12) nothing. On "Desktop Effects - System Settings" tried to turn it back on by clicking the suspend/resume button, and again nothing, altough it did say composing enabled. I should have known since it does not even enable the "Apply" button. So, by disabling and enabling desktop effects "Apply" gets enabled, and after clicking it, I got something like "failed to enable composting at least with your current settings"... Not very informative. Also, a message popped up saying that it had failed to enable all the effects that I have selected. (minimizing animation, window open animation, etc.) Then I tried to restart the computer, with no effect. Tried to check the driver, it could have changed somehow, but no, the driver was still nvidia closed source binary. Tried a few applications that use opengl, textures, blending, everything ran normally. Glxinfo states direct rendering enabled. Then I tried to select xrender, and it finally enabled the desktops effects, but super slow... Then I tried to select the OpenGL driver again, no luck, it always gives an error, and gets me back to the previous xrender config. Finally, I noticed the "Disable functionality checks" which got me wondering what it was. I click on it, and "Apply" and "OpenGL" and bam! That did the trick. Desktop effects back working nice and fast. So if you have the same problem, just try to click that wonderful box, maybe it will help. Now, what I don't know why I never needed that, and now all of the sudden I do. I haven't changed anything since I compiled kde. I'm still using nvidia-drivers-180.44 (time to change...), it was working just perfectly but all of the sudden after a reboot it was gone?!?!? I smell buggg. Where? I don't know.
