I need to edit
Problem is it is owned by root, and I can only open it as read only.
How can I open it for editing ? Please note I'm new to Linux.
If you are in the sudoers file, you can edit the file by typing
Hold down Alt and press F2, it'll invoke the "run" dialog. Type in "gksu gedit /etc/lirc/lircd.conf" (without the quotes) [mind the forward slash / as opposed to the backslash \ that you typed in your question]. It'll ask for root password. Enter password and hit enter. It'll open the file. Make changes and save file (click button or do Ctrl+S).
