Lock Screen - Screen Shield - Avoid 3 Up Scrolling Arrows. Ubuntu 18.04

  • 772

By following this excellent question and answer How do I prevent the blank screensaver when using keyboard shortcut to lock the computer? I just made my Lock Screen persistent.

However, I don't want to see those transient 3 upward scrolling arrows on the screen at 08:25 34th second & 40th second. above the date feild Friday, December 14 in the animated gif.

How to achieve this?

    I tried to make the arrows invisible by hacking /usr/share/gnome-shell/theme/ubuntu.css file.

    Disclaimer: playing with shell files is very dangerous, small mistakes will stop access to GNOME desktop session. Only tty will work. I have several times reinstalled Ubuntu in such cases. although I have successfully achieved the required. Do this on your own risk.

    found this part,

    .screen-shield-arrows Gjs_Arrow {
  color: white;
  width: 80px;
  height: 48px;
  -arrow-thickness: 12px;
  -arrow-shadow: 0 1px 1px rgba(0, 0, 0, 0.4); }

    and made it to

    .screen-shield-arrows Gjs_Arrow {
  color: white;
  width: 0px;
  height:0px;
  -arrow-thickness: 12px;
  -arrow-shadow: 0 1px 1px rgba(0, 0, 0, 0.4); }

    hack: width & height fields made to 0px

    enter image description here

    Observe that at every 7th second, arrows should be visible..
    now no more with the above edits in /usr/share/gnome-shell/theme/ubuntu.css file.
