Hello everyone!

I just installed ubuntu 12.10 and KDE over it. For the first week my system works as butter.

But suddenly I have started experience hangs/crashes. After approsimately 15-20 minutes of usage my system hangs and I get the subjected error message. Only option left after this is hard reset!!! Please help

At system startup i get a warning message that ubunut had an internal error and the error details show:

/usr/bin/nepomukservicestub is the thing that crashed. have already sent a bug report as it asks me.


/var/log/syslog snippet:

Not that I understand the message but my guess is that somthing that involve nouveau probably is problem with the nouveau driver. Have you tried the closed Nvidia driver?

Installing NVIDIA closed driver works. Thanks.!

$sudo apt-get --install nvidia-current.
