Perhaps the theory of backing up your data before fiddling with your system is unknown to you?

Your attitude stinks. Don't blame the tutorial for your own short-sightedness. ALWAYS backup before making huge system changes. And you can't say installing an entire desktop enviroment doesn't count as a huge change.

There are several options and warnings, dialogs and logfiles availble on your system that will highlight the preposed changes before the package installs, and list the changes made afterwards. Using thse, you may be able to correct your system. Of course, a backup beforehand would be easier to restore, but well done for your forward thinking, hm?

I would give more details to you about how to diagnose/correct your problems, but I'm sure you would appreciate my HELPFUL advice anyway.

To other users, be warned. Backing up is not as time consuming as one may think. Most people can have backed up in the time it has took to search for, and read these guides. Researching beforehand is good, and backing up in the meantime is better.

i installed gnome in kubuntu 9.10, and immediately it took out wicd and removed my audio driver. i reinstalled wicd, but now my connection is SLOW. i uninstalled gnome, but my audio driver is still not working – instead i'm stuck with pulse, and now every time i click a button in browser there's a stupid sound that i can't get rid of.

thanks a million for your HELPFUL tutorial.

sudo aptitude remove ubuntu-desktop

Really nice and interesting.

Thanks

Some tasks require a bit more skill, and require 'old fashioned' command line entry (usuakkl Alt-F2, or an application such as Terminal or my favourite, Konsole). Here Ubuntu offers both super-user access and sudo (super user – DO), which allows users to perform some super-user tasks. For this, I find that KDE is best, because Konsole allows 'clipboard cut and paste' (e.g. from internet posts like this), but only using the right mouse button (this is a bit awkward at first, as you can not paste anywhere but at the end – it is not possible to paste in the middle of a part-entered command).

Finally, Linux environments may be cash light, but they can be labor intensive and challenging to master. So back-up your work regularly, and do not be afraid to play. Remember though that super-user is scary, and try not to use it unless you HAVE recently backed up somewhere safe – like a memory stick or USB disk that you can unplug!

This should help you remember
