Update done wrong?

Hello!
Last week I did an update - probably something wrong (it was quite a lot of packages to update - all around 25). Update on my computer did automatically. I approved all that was needed to upgrade. I was surprised a little that so much, but I understood everything, because recently I was doing updates and usually come out 1-2. At the end came, that computer must be restarted.
Now I can not go to Linux in normally, only in safe mode. When I try to access it normally get a black screen and I have to do restart the computer. Therefore remains safe mode.
I can not easily give my computer into standby. I get an inscription about the problem (KDE screen lock).

And here they appear in the tab Developer Information:

Application: Blokowanie ekranu KDE (kscreenlocker), signal: Segmentation fault

At the end came, that computer must be restarted.

This indicates that you updated the kernel and that you (possibly) have to re-install the graphic driver for you graphics card. Can you please post some information about your system?
