[TIBOR]

Zdravim vsetkych.Po instalacii compiz mi nvidia-settings hlasi

error: unable to determine number of nvidia gpu-s on  ':0.0'.
error: unable to determine number of nvidia frame lock devices on  ':0.0'.
error: unable to open file "cesta k mojmu home adresaru"/.nvidia-settings-rc' for writing.

a po otvoreni okna nemam ziadne moznosti nastavenia GK.
Instalaciu compiz som robil podla http://forum.ubuntu.cz/viewtopic.php?id=1236
Neviete co by pomohlo aby som bezpecne spojazdnil nv-settings?
Pripadne podla vas pomoze preinstalovanie aj v pripade ked sa pouziva /usr/bin/Xgl namiesto /etc/X11/X
