Kwin: OpenGL compositing disabled

Question

Recently I tried to start KDM via inittab as mentioned in the wiki. Before that I used daemon and everything worked fine using Nvidia driver. After the change (for some reason) compositing is gone with following message:
[tuhyk@dell documents]$ glxinfo | grep -i direct
direct rendering: Yes
    GL_EXT_direct_state_access, GL_EXT_draw_range_elements, GL_EXT_fog_coord,
Any ideas? Return back to daemon did not help.
EDIT: Xrender setting works, OpenGL does not at all. I discovered that issue is not user related. Also, new Xorg.conf generated via nvidia-xconfig did not help. Reinstalling nvidia and nvidia-utils packages did not help either.

Answer 1

After reading a couple of previsou threads I tried compiz:
[tuhyk@dell documents]$ fusion-icon
* Detected Session: kde
* Searching for installed applications...
* NVIDIA on Xorg detected, exporting: __GL_YIELD=NOTHING
* Using the GTK Interface
* Starting Compiz
... executing: compiz --replace --sm-disable --ignore-desktop-hints ccp
compiz (core) - Error: Plugin 'text' not loaded.
compiz (ring) - Warn: No compatible text plugin found.
* Setting window manager to KWin

Compiz seems to work fine...
And for the record my xorg.conf. I did not alter its configuration before the error occured.
