help, my ubuntu is bumpy

[emuobo]

My first post in the ubuntu forums,please take it lightly with me.

I am a 1yr+ ubuntu user and recently i changed my pc to a laptop running core 2 duo 2.16 ghz and 3gb ram and intel x4500 GPU.I noticed a decline in performance in the new PC (my old one was a pentium d and 512mb ram and intel GMA 950 @ 128MB VGA which was a dumb Pc).I understand that my new intel chip gm45/gm47 is not too nice on my kernel 2.6.27-7.

recently, i installed debian lenny and noticed my performance skyrocket.Now , what went wrong?My debian kernel was 2.6.26-1.
IMHO that version of kernel was better than the ubuntu's own.Please i need help if whether a kernel update will help,

I couldnt just use ubuntu after seeing such speed and responsiveness with debian.

or maybe a kernel downgrade? i already can compile a kernel.
:confused::confused:

Hi emuobo,

Welcome to the forums - sounds like you've already got a fair bit of experience though. Intel graphics are, apparently, an issue in Jaunty (due to be fixed in Karmic). Have you tried this thread:
http://ubuntuforums.org/showthread.php?t=1130582

It has lots of helpful hints to improve things. Hope it helps - if not, someone with more experience of your hardware on the forums should be able to help.
