Ok, so first of all I had an issue where the whole system would completely freeze and I'd have to hard reset it all the time. I googled around a bit and found a bunch of people saying that updating the kernel is a good idea. I followed the step by step instructions and , voila, the system stopped randomly freezing.


Unfortunately, after a few weeks, an unbelievable lagginess has set in (typing this, I'm about a sentence ahead of the words on the screen actually showing up). I tried to follow the steps listed in this thread (http://askubuntu.com/questions/133181/ubuntu-12-04-x64-very-slow-response-and-sluggishness) but ran into another problem - my update manager no longer works. It tells me the package information has not been updated in 523 days (which isn't true). When I try to update it tells me I have no internet connection.


This lead me to another thread. I try to update via the terminal, as suggested, and get the following output:

W: Failed to fetch http://ppa.launchpad.net/cscarney/unity-web-place/ubuntu/dists/precise/main/source/Sources 404 Not Found

W: Failed to fetch http://ppa.launchpad.net/cscarney/unity-web-place/ubuntu/dists/precise/main/binary-i386/Packages 404 Not Found

Then it tells me there are no updates.

sudo apt-get upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.
I feel like I need to update my graphics driver to fix the lagginess but I don't seem to be able to update anything. Please help!

The ppa for unity-web-place does not seem to have a version for precise.
Did you remove the entry from your sources?

If not, open the update manager, go to settings click and open, then go to other software.
Find the entries for the ppa and uncheck, and/or remove them.
close window, and click check.
With those entires removed the system should produce a clean up-to-date package listing.
Then install any updates that show up.

I do not know if this will resolve the lagginess, though.
But the system will be as up-to-date as possible.

This seems to have worked, for now - i can now run updates and the lagging seems to have gone as well. Thanks a lot!
