Just a couple of adjustments that I usually make whenever I use GNOME as my default DE

Changing the timeout of the “App is not responding” popup.

The default time is set to 5 seconds. In order to change it to a higher value or to remove it, follow these steps.

  1. Open the terminal and paste these values:

To 60 seconds:

gsettings set org.gnome.mutter check-alive-timeout 60000

To completely disable it:

gsettings set org.gnome.mutter check-alive-timeout 0
  1. Done

Changing the volume increment step

If I am not mistaken, the default value of the step is 6% and I don’t like this default value it is too much when I am switching volume using my keyboard. Follow these steps to change the value:

  1. Open the terminal and set the desired value (I like to set at 2%)
gsettings set org.gnome.settings-daemon.plugins.media-keys volume-step 2
  1. Check if the changes were applied by running this command:
gsettings get org.gnome.settings-daemon.plugins.media-keys volume-step
  1. Done
