cannot start kpowersave

Hello I am still trying 13.04 out, but when I tried to start kpowersave I receive Fontconfig warning: "/etc/fonts/conf.d/50-user.conf", line 9: reading configurations from ~/.fonts.conf is deprecated. and it does start up but then I cannot select anything, hibernate suspend no such option pop up. Which BTW happens also when I use control alt delete, there is no suspend or hibernate option. which I find odd. thanks Uwe Brauer
