Yeah..I understand I won't be able to compile using YaST. Just had a
dilemma as to install a new pre-compiled kernel or get a kernel from
kernel.org and build it myself.

Well..as you have rightly said, improvement in performance will come by
improvement in Hardware. I understand that my hardware isn't too great but
the problem is quite serious.

Whenever I minimize or maximize windows, and if I am playing amaroK at the
same time, then amaroK stops playing until the window maximizes or minimizes
and then continues playing.

This doesn't happen on other Linices I have installed (Slackware Current)
. I didn't happen on SuSE 9.3 either. But only on this version...I am
experiencing this problem. SuSE 10.0


Also, there are other problems. The mouse doesn't move smoothly on the
screen sometimes. The CPU Usage is always close to 100% (thats what worries
me the most) .
