Why is it bad to run as root?
I recently fully switched from Windows into Ubuntu. And of course I loved Ubuntu. But the most annoying thing is, system requires password every single time you do something. Is there any way to configure system so that, to enter the password only on logon screen. I mean 1 time you enter password and logon. Then system must know that you're his boss, and no need to ask every time for password. I don't want to change any system file for this purpose, but if there is any legal way to do it, I'd be very happy.
Thanks in advance for wasting your time and trying to help
