I am a first time user of Ubuntu. I have installed Ubuntu 12.04 dual boot with Windows. Ubuntu is screwing up the Windows clock. I looked this up and found the following lines to use:
gedit /etc/default/rcS(in Terminal)
UTC=no(in edit tool)
rcS file will not save. The editing tool won't let me to save it. The editing program says I do not have permission. I am a noob. If there is a clear guide on how to get permission to edit and save
rcS, step by step with actual command lines if possible, please direct me to it. If there is a very quick way to get permission to edit this file prior to editing, please let me know.
