Ubuntu 20.04 Login with no "see password" option

  • 772

is there a way to disable the eye icon in the login screen to prevent from someone "accidentally" turning it on and thus showing their password in plain sight? Thank you!

    Assuming you have a fresh install of Ubuntu 20.04, The workaround is to set the eye-icon size to 1px so that it is not visible and not reactive..

    To use the workaround

    Download the script from github with below command..

    wget -qO - https://github.com/PRATAP-KUMAR/focalgdm3/archive/remove-eye-icon.tar.gz | tar zx --strip-components=1 focalgdm3-remove-eye-icon/focalgdm3

    Run the command

    sudo ./focalgdm3 \#4f194c

    Optionally you may change the color #4f194c in above command with any color or you may replace the color \#4f194c with an absolute path of the Image if you wish an Image as background.

    For reverting back to normal

    Run the command

    sudo ./focalgdm3 --reset

    The above works only for login screen.. and not for lock screen, to use the same theme file for lock screen, we need to configure it separately.

    Configuring the same file for lockscreen

    copy the gresource file used for login screen with below command to system default folder

    sudo cp /usr/local/share/gnome-shell/theme/custom/custom-gnome-shell-theme.gresource /usr/share/gnome-shell/theme/Yaru/

    enter image description here

    $ ls /usr/share/gnome-shell/theme/Yaru/
custom-gnome-shell-theme.gresource  gnome-shell-theme.gresource
$

    Now to get away the changes we are doing from system upgrades.. make a local copy of the file /usr/share/gnome-shell/modes/ubuntu.json

    sudo mkdir -p /usr/local/share/gnome-shell/modes
cp /usr/share/gnome-shell/modes/ubuntu.json /usr/local/share/gnome-shell/modes

    Open the file ubuntu.json

    sudo -H gedit /usr/local/share/gnome-shell/modes/ubuntu.json

    Now edit the ubuntu.json file to use our login screen gdm3.css file with below content..

    {
    "parentMode": "user",
    "stylesheetName": "gdm3.css",
    "themeResourceName": "theme/Yaru/custom-gnome-shell-theme.gresource",
    "debugFlags": ["backtrace-crashes-all"],
    "enabledExtensions": ["[email protected]", "[email protected]", "desktop-icons@csoriano"]
}

    Now reboot to see the changes..

    enter image description here

    To revert back to normal, remove the two files we created for lock screen purpose..

    sudo rm /usr/local/share/gnome-shell/modes/ubuntu.json /usr/share/gnome-shell/theme/Yaru/custom-gnome-shell-theme.gresource
