slow

I have tried for quite a while now to reduce my boot time, disabled some startup items, removed packages that were causing crashes after boot, removed ureadahead pack files, reinstalled ureadahead, uninstalled ureadahead and installed e4rat....and nothing has made that much difference. e4rat made the biggest difference with a reduction of a few seconds but my boot time is still around 80 seconds.

Can anyone help?

Will final version of 12.04 use the power management changes found in kernel 3.3

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version. In this case, kernel 3.3 has seen some very good power management enhancements that are… >>> More
