Safe way to edit your DM

#1 Post by ponasm »

Hey. I'm trying to change the Gnome Display Manager a bit, and I was wondering if there was a way to do it and test the changes without the risk of damaging my computer.
And also, I wanted to know the correct way to do it. Shall I download the source of the package with apt-get, then build a .deb file and edit it's contents, or are these kind of things done another way?

You know, look around, see how it works, and add a few lines to some file. Not much.

Code: Select all

apt-get source gdm3
You need some deb-src lines in your sources.list though.

Backup your computer first :)

Or test the altered package in a virtual machine, I recommend QEMU/KVM.

Does GDM have a user configuration file?

I don't use it but what I would do is to copy any and all files that I wanted to change and save under my username. Something like gdm.config.pon ; something of the sort. Then, when things go wrong (which they will) you'd have a drop-in replacement.

Do as much as possible using CLI so that your changes are saved and can be seen when you have to do a CLI rescue.

Take notes on a piece of paper.

i am wondering if op just wants to change some configuration, or actually change the program gdm itself?
unless they specify, there's no clear recommendation to make here.
