Hi,

When Ctrl+Alt+L for session lockdown, there is a mouse clickable option to start a new session. What can I do to hide this option? I only want my user to show, with the input field for password entry. This is just a personalization issue, not a real problem.

Thanks!

I wish I knew too! I came here to ask the same question.

How to Customize the Lock Screen on KDE: https://www.maketecheasier.com/customiz ... ck-screen/

Changing: /usr/share/kde4/apps/ksmserver/screenlocker/org.kde.passworddialog/contents/ui/Greeter.qml

From

Code: Select all

visible: switchUserEnabled

to

Code: Select all

visible: false

Result:



Plasma 5

With the plasma 5 the screen locking qml code is part of the Look and Feel theme.

Paths
System: /usr/share/plasma/look-and-feel/<THEME_NAME>
User: ~/.local/share/plasma/look-and-feel/<THEME_NAME>




With the Plasma 5.8.4 based theme. Changing .../contents/lockscreen/LockScreenUi.qml:

From:

Code: Select all

if (sessionsModel.canStartNewSession) {

to

Code: Select all

if (false) {

Result:

Brilliant--thanks Rog!

To do it properly™ use KDE's Kiosk Framework:

Add the following to ~/.config/kdeglobals (or /etc/xdg/kdeglobals if it should be for all users, in Plasma 4 should be ~/.kde/kdeglobals or ~/.kde4/kdeglobals iirc)

Code: Select all

[KDE Action Restrictions][$i]
action/start_new_session=false


The [$i] is so that the user cannot change or override it (normally stuff in ~/.config takes precendence over /etc/xdg)

There's also a action/switch_user

Same kind of: viewtopic.php?f=289&p=368119#p368058

Thanks, kbroulik. It would be nice to expose that setting in the GUI.
