How to change resolution and refresh rate in GNOME desktop every time you boot up using a script and a desktop file.

README.md

1. Create a executable script. 🙂

Open your terminal first: Press the start button and type terminal and select the Console, Konsole, Terminal or anything but in the result of search.

Use your desired editor to create a new file with .sh in the end of the file at any places. Just remember don't delete it.

For vim, you type vi and path of your like.

Example: vi /home/user/abc.sh

For nano you type nano and path of your like.

Example: nano /home/user/abc.sh

2. Getting the "modeline" thingy 😎

Before we get to the editing part, you need something named "modeline" which represents your configuration by into numbers code.

Exit the editor.

For vim, first press the esc button on your keyboard to exit INSERT mode and enter :qw to exit

For nano, press Control, X together in your keyboard and press Y to exit and save the script.

We're back to the screen to proceed the next step. If you still in the editor, try again.

If you want the resolution is 1920x1080 120hz. Then type command gtf 1920 1080 120. Change them as you want.

You will get the result like the below photo (ofc without the logo lol)

Copy all the text after "Modeline" and the space

3. Filling the script that we create in step 1. 😝

Before we get to filling it. We need to get the display that your using.

Create a new tab in your terminal and type in xrandr -q | grep -i connected primary

Use this as a reference to my next steps with "display"

Repeat all the steps of step 1.

After your editor appeared on your screen with your script created before, enter this.

#!/bin/bash
xrandr --newmode "the copied code"
xrandr --addmode "display" "the quoted text in the copied code"
xrandr --output "display" --mode "the quoted text in the copied code"

Save the script and exit the editor as I said before.

4. Make the script executable. 🤨

There's something missing in this script which cannot make it being executed which is the permission.

Open your terminal and type the below.

chmod +x "your script place"
chmod 775 "your script place"

You're done with this script. You can move on to the next step which is the final step of this tutorial.

5. Make it run automatically when you boot up 🥳

Open your terminal.

Create a new file at /etc/xdg/autostart/ but now the name isn't end with .sh but .desktop.

Enter these texts in the file.

[Desktop Entry]
Name="You like"
Exec="Your script path"
Terminal=false
Type=Application
X-GNOME-Autostart-enabled=true

Exit and save it as I said before.

Reboot the computer and if it changes as you want it. You're finished and COMPLETED this tutorial.

Congrats of you followed the tutorial and suceed. This means you're a semi-pro in Linux now.

You can now sit back and enjoy your auto resolution script in every boot up!!!
