KDE Fail start

Hello all.
I have trouble with my OpenSuse 11.1 box. Some time my KDE 4 work successfully. After reboot, my KDE not automatically start.
Browse my /var/log/Xorg.o.log I see that error with glx module. I try comment in /etc/X11/xorg.conf load glx, but problem remain.
I also try use default xorg.conf


Xorg -configure
cp /root/xorg.conf.new /etc/X11/xorg.conf

Test Xorg -config /etc/X11/xorg.conf succesfully. No error in /var/log/Xorg.o.log.
I try run startkde, but I get error that could’t connect to my X server or $DESKTOP not set. Then I create /root/.xinitrc and add line ‘exec startkde’. Run command startx, X shell start and I see that ‘kstartupconfig4 does not exist or fails’. In shell I see this errors:


/usr/bin/kde4-config: symbol lookup error: /usr/lib/libQtNetwork.so.4: undefined symbol: _ZN14Q...
/usr/bin/kde4-migrate: symbol lookup error: /usr/bin/kde4-migrate: undefined symbol: _ZN9QL...
kstartupconfig4: symbol lookup error: /usr/lib/libQtNetwork.so.4: undefined symbol: _ZN14Object

What’s this a how I may find solution?
Thank all.

Start Software Management and filter by repo, select ‘System’ and Try to do unconditional update of all packages.

Did you update Xorg packages? If yes, then a reinstall of NVidia or ATI driver could solve your problem.

No, i don’t update any packages.
