12.04upgrade
I downloaded the 12.04 and used Unetbootin. Then when I tried to install, it asked whether to upgrade, so I upgraded (from 10.04). I think it didn't format my file system, as some of the apps are intact. But I doubt, if the installation has taken more space in addition to previous 10.04.
But now, after upgrade, loading apps have become very slow and also when I browse the youtube, the video and audio isn't smooth. I feel the upgrade has bloated my system.
Any solutions pls?
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/
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:

For any operating system for any time upgrading from older version did not worked well for me. I always advice clean install. It is more easy to install your previous applications and restore your application specific files instead of cope with numerous errors after an upgrade. I have witnessed lots of unsuccessful Ubuntu upgrade attempts before and my advice is "Do not upgrade!".
