[drakeman007]

Thanks Guys to your help, i think i found the solution to find the packages installed via command line,
i put
dpkg -l | grep packagename ( in this case, openoffice)

and it list the openoffice packages and now i have to uninstall one by one!! thanks for your help guys!

Hi! I have kinda a the same problem, I installed a whole bunch of program (sound editing) with the terminal and let terminal download and install all the necessary files. And now my PC wont start to desktop. I type in my password and press enter, the log in sound plays and a blue screen appears and nothing happens, I can however open terminal and open program with that, but is there away to unstall all sound editing program with the same way I installed it? Just type something and it will unstall automatically? Or do I need to unstall one-by-one?
