Git rebase vs merge - there can be only one.

Published: February 24, 2026

Introduction

Rebase vs merge, which is better? There are a lot of online discussions about these two “workflows”. One is pro-rebasing and the other swears by merging. Both sides are stuck in their own thinking and both think they are right. So which is it? In my opinion: neither or both. Before you get defensive, hear me out. I’ll try to explain this in the following post.

TL;DR

Rebase is a tool used while developing. Merging is a tool used for incorporating your branch into a target branch. Both tools or workflows serve each other in the end.

Question: How can I prevent multiple logins via lightDM

Published: February 9, 2026

Answer

I use xscreensaver and to forbid it:

! in .Xresources
xscreensaver.splash: false
! Set to nothing makes user switching not possible
*.newLoginCommand:

Lightdm supports .d directories, by default they aren’t created on Debian but upstream documents them clearly. In other words: /etc/lightdm/lightdm.conf.d/ is read.

Which means you need to drop a file, /etc/lightdm/lightdm.conf.d/10-local-overrides.conf and add the content:

[Seat:*]
allow-user-switching=false
allow-guest=false

To check your configuration:

lightdm --show-config
