Updates. I think compositing now should work everywhere where it can

(with 'export __GL_YIELD=NOTHING' for nVidia users and
'export LIBGL_ALWAYS_INDIRECT=1' for others for better performance).

For the TFP mode AIGLX needs to work. Also, it seems necessary to do

Configuration options:
======================
All general configuration option are in group [Translucency] in kwinrc config file:
UseTranslucency=<true|false> - enables/disables compositing support
GLMode=<TFP|SHM|Fallback> - selects texture creating mode
RefreshRate=<number> - manually specified refresh rate, should be usually automatically detected
GLDirect=<true|false> - enables/disables direct rendering
GLVSync=<true|false> - enables/disables synchronizing with monitor refresh
There is configuration module for most options. If you need to manually disable compositing,
use the following command:
kwriteconfig --file kwinrc --group Compositing --key Enabled --type bool false
