Ubuntu 9.04 on my HP Pavilion dv5-1153ei Notebook

I am very disappointed in Ubuntu 9.04 performance on my laptop. I had Ubuntu 9.04 installed in my HP Pavillion dv5-115ei laptop with the following specs:

  • 2GHZ Intel Core 2 Dou processor T5800
  • 2GB RAM
  • 512MB NVIDIA GeForce 9600M GT video card
Ubuntu GDM

For some reason its running slower than the previous version of Ubuntu (Ubuntu 8.10) that I am using before. Its becomes completely unresponsive if I am using multiple applications at the same time especially when I am running firefox. Running firefox is very frustrating, it freezes every 5 minutes or so, scroll on any windows takes time. If I've minimized anything for some time, it takes forever for it to reappear.

My CPU usage is not unusually high, and I am using less than 50% of my 2 GB of RAM. Also during the shutdown process, the screen gets white and the laptop does not shutdown at all.

Ubuntu Error

I don't think its a hardware issue but something is wrong with this version of Ubuntu. I already tried google for possible solutions for this problem but with no luck. Right now I am planning to downgrade to the previous version of Ubuntu or just simply give Fedora a shot.
