Today we go with a very simple tutorial but that allows us to give a very professional touch to our Ubuntu system. We will do this by customizing the Login screen that falls on the program Lightdm in the case of Ubuntu.
Lightdm is Ubuntu’s standard session manager since the incorporation of Unity. Its modification is very simple and not in danger. The first thing we need to do is have on hand the images and icons we want to modify, as well as know the addresses of the files to make the customization faster.
Dconf-tools, tool to modify the Login screen
To do the customization we will have to open the dconf program, Which usually comes by default installed on Ubuntu but if we do not have it installed, open the console and type
sudo apt-get install dconf-tools
we will install the dconf, A very powerful tool that will allow us to make the modification without any danger.
Now we go to the dash and type dconf, we open the program and the following screen will appear
Dconf is a program similar to the Windows registry: a column on the left with programs that can be modified and / or customized, on the right the options that can be modified.
In the left column we look com → Canonical → unity-greeter . Then mark us will appear in the right column the options that we can modify in our login screen.
The options we can touch are the following:
- background: It is the background image, to change it we only have to indicate the direction of the new image that we want to put and press the integer.
- Background-color: Indicates the color we want to put on the login screen. It’s a good background alternative if we don’t want to have an image.
- Draw-grid: It is the Ubuntu watermark, we can only change the selection option, adding or not the watermark.
- Draw-user-backgrounds: By checking this option we set the wallpaper of our desktop as the background image.
- Font-name: Font and size to use on the Login screen
- Icon-theme-name: Name of the icon theme we will use.
- logo: This is the image that will be displayed at the bottom of the screen. It should be 245 × 43 in size.
- OnScreen keyboard: This option will enable a virtual keyboard to enter the characters on the login screen.
- Theme-name: We will indicate the desktop theme we want to use.
Now all you have to do is modify it to your liking. The options are a bit limited but we can change the look to a professional level that other operating systems do not allow us like Windows. One last detail, if you want to check the modifications you can open the console and type this
lightdm -test-mode -debug
this command will allow us to run and view the login screen without logging off the session we are using. Also comment that Dconf gives us the option to return everything to how it was before modifying it using the button “set defaultThat is, we can customize it without any problems.
