How the GDM login interface on Linux adapts to high split screen

Guide

GDM (Gnome Desktop manager) is a GNOME display environment manager, which is a small program (script) running in the background for running your X session, displaying a login interface and allowing you to log in when you enter your password correctly. GDM wins XDm in all respects and does not xdm so many loopholes.

GDM (Gnome Desktop manager) is a GNOME display environment manager, which is a small program (script) running in the background for running your X session, displaying a login interface and allowing you to log in when you enter your password correctly. GDM wins XDm in all respects and does not xdm so many loopholes. It does not use any code from XDM. It supports XDMCP and actually expands the XDMCP, bringing some features I think XDm are missing (but still compatible with XDm XDMCP).

Background introduction

Linux for high-split screen adaptive is not very good, the use of the process due to high screen resolution, the system adjusts the zoom level factor is large, directly caused the display window is too large. I Google the relevant information, today write a how to modify the GDM login interface and the GNOME interface zoom level factor of the tutorial.

For high-split screens, the GDM login screen is very large, and the GNOME desktop is occasionally self-adapting.

Workaround

GNOME Desktop

Let's start by introducing the GNOME desktop zoom level modification method.

The simplest solution is to open the Gnome-tweak-tool to see the zoom Value Scale of the window and adjust it to 1
Can. But sometimes it has a value of 1 in case the screen is still very large, adjust it to 2 without any change. At this point, you need to use

Gsettings

command to see the scale value found is actually not 1, but 2 .

$ gsettings Get Org.gnome.desktop.interface Scaling-factorunit32 2

This means that the current zoom level is actually 2and is adjusted to 1 using the following command.

$ gsettings Set Org.gnome.desktop.interface Scaling-factor 1

GDM Login Desktop

All right, here's the point. In fact, the way to modify the same as the above method.

Configure X Service access rights:

# Xhost +SI:LOCALUSER:GDM

Open dconf Tool directly modify, if not dconf please install first:

$ sudo DNF install Dconf-editor

$ sudo-u GDM Dconf-editor

The following interface is displayed:

650) this.width=650; "class=" AlignCenter size-full wp-image-62953 "src=" http://www.linuxprobe.com/wp-content/ Uploads/2017/04/084254g3a2efx5zr23g5gz-2-1.png "width=" "height=" 646 "style=" Height:auto;margin-left:auto; Margin-right:auto; "/>

Then follow the path /org/gnome/desktop/gnome/interface Enter, the drop-down scroll bar to find the scaling-factor option, modified to 1 .

650) this.width=650; "class=" AlignCenter size-full wp-image-62954 "src=" http://www.linuxprobe.com/wp-content/ Uploads/2017/04/084254g3a2efx5zr23g5gz-2-2.png "width=" "height=" 646 "style=" Height:auto;margin-left:auto; Margin-right:auto; "/>

Restart the system at this time, you will find the login interface is not so ugly!!!

Tip: Dconf-editor can also modify GDM's GTK theme, icon theme, cursor theme, background.
