12.04upgrade
After upgrading to 12.04, my system became terribly slow. Applications are running very slowly and become very unresponsive. I am not able to do anything. Before upgrading, it was running very good, even better than Windows.
I also often get errors when I try to run an application
What should I do? I want to make my Ubuntu work faster again. Please help me.
Since today (at least for me). In the Ubuntu 32 bit and 64 bit version of 12.04, updating to the latest Nvidia 295.49 fixed all lag problems.
Confirmed on both 32/64 after restarting and toying around with several windows and wine apps. Everything feels correct again.
Here is the launchpad information about it.
But I can add to it that it should also include the 9500 GT, 220 GT and 440 GT. All of them were also suffering from the same problem but now is gone.
Problems like the following which I was having are gone:
Ideapad Z580 users seem to be experiencing an ACPI issue. Booting with ACPI=Off works but I have read this cripples hyperthreading (so what is the point?) Here is a related thread:

I had a problem with an upgrade a few years ago that made my laptop unusably slow. I eventually found the problem was a malfunctioning CPU frequency governor, which meant my system never got off its lowest CPU frequency. The problem went away when I made the system use the conservative governor by default instead of the ondemand one. For more on frequency scaling, see for example: https://idebian.wordpress.com/2008/06/22/cpu-frequency-scaling-in-linux/
