Hello !
When I put the computer to sleep, and then wake it up, the bottom KDE bar is lost, and the title bar at the top of each application is gone. The only thing remaining is the desktop widget showing the files in my Desktop directory.
I just installed Kubuntu 13.04 yesterday, I did not do any configuration, besides updating the source server and installing all system updates (up to July 15). The computer is Desktop computer, not a laptop.
Any pointers to get started on this problem?

It's a bit annoying, anyone has seem this problem before?
When I resume from sleep, there is not even the contextual menu upon a right click. Looks like if the KDE shell is gone.
Some more information about my system:
uname -a

Is this more a Kubuntu / KDE / Nouveau driver / Video card or Xorg problem ?
Is this the right subforum to ask for this problem ?

I am looking at syslog, and found these messages :

Then, there is a few thousands of these messages :

Timestamps of the events :
21:58:24 boot time
22:39:55 sleep time
05:25:23 wake up time
Are these TRAP and SHADER events normal ?
