my mouse pointer is missing after updates installed

Hi,
I’ve been using OpenSUSE 11.1 on my Dell Studio 15 for a year and I’ve never had problems till yesterday. The Kupdateapplet advised me to install 4 available updates and I accepted (I always do so). Well, after rebooting my computer, the pointer was disappeared. How could I solve my problem?
Ah, important: I’m not an expert (or better: I know just elementary things about Linux), so, please, try to answer me using easy words :shame:
Thanks! :wink:
