Is there any way to set default login screen brightness? Because by default it is too bright and hurts my eyes in dark room.

P.S. I am on KDE 5.8.4.

Any help is appreciated.

As default the KDE is using the SDDM. The default plasma 5 greeter theme is the Breeze.


Plasma 5.8.4 Breeze SDDM theme

The Plasma 5.8.4 Breeze SDDM theme background is set at the /usr/share/sddm/themes/breeze/Background.qml. As default the background color is '#1d99f3'. The user can change a darker color to the background. Color QML Basic Type: http://doc.qt.io/qt-5/qml-color.html



Image background brightness and contrast can be set with the BrightnessContrast QML Type: http://doc.qt.io/qt-5/qml-qtgraphicalef ... trast.html .


Breeze Nightmode

Copying the /usr/share/sddm/themes/breeze/ to /usr/share/sddm/themes/breeze-nightmode/.

Editing the metadata.desktop:

Code: Select all

}

When right double clicking the Breeze Nightmode greeter the background is set to the 'midnightblue'. If left double clicked the background color is set to the '#1d99f3'.




With the background image there is an option to lower the brightness pressing and holding the right mouse button. If left mouse button is pressed and hold the brightness will return to the default.

Thanks for such a detailed answer.

I knew it was sddm and have read man page for sddm and sddm.conf but there is no such info there.

I will play around with sddm settings later today.

Btw what is the name of theme from last screenshot? My default sddm theme doesn't have keyboard layout button in bottom left corner and background image looks nice.

All images are from the standard Breeze theme. I only added the mouse actions to the Background.qml.

The background image is 'Dreamworks-Concept-Art-Collection-22.jpg': http://www.iamag.co/features/dreamworks ... ollection/

Bug 370521 - [Regresion] SDDM breeze theme unable to change backgound: https://bugs.kde.org/show_bug.cgi?id=370521

At the beta stage the kcm-sddm module doesn't have the color picker. The user can add to the /usr/share/sddm/themes/breeze/theme.conf.user the background color and the background type to the configuration file - example:

Code: Select all

[General]
type=color
color=darkgreen


Colors are the Qt supported colors: http://doc.qt.io/qt-5/qml-color.html

...another theme: SDDM Theme Breeze Slider
https://store.kde.org/p/1174674/

SDDM Theme Breeze Slider is a modification of the standard Breeze (Plasma 5.9.4) theme.

This sddm theme is using a semitransparent (color: "#F2000000") rectangle. The sddm texts are on the rectangle and moving out the sight when not needed.



The rectangle is moving:
- up when up arrow is pressed
- down when the down arrow is pressed.
- mouse movement will also trigger the down movement.
- after 3 minute inactivity the rectangle is sliding out of sight.

SDDM language and locales - in general

The SDDM is following the system locales: What locale settings sddm respects?
https://www.bountysource.com/issues/379 ... m-respects


Example at here (Arch Linux)

Writing /etc/default/locale

Code: Select all

LC_TIME="en_US.utf8"

and adding to the /lib/systemd/system/sddm.service

Code: Select all

[Service]

EnvironmentFile=-/etc/default/locale

After reboot the time format is using US time format.

Note !
When launched from the terminal:

Code: Select all

sddm-greeter --test --theme /usr/share/sddm/themes/breeze-slider/

The SDDM is using users locales.

Thank you so much for the support and speedy reply. This worked perfectly.

Hi! I've been trying to change the initial icons for login (power shutdown suspend reboot) But i cannot seem to locate where the images are to change them. I've done extensive file searching but still can't find it, unless i've already changed it and some sort of icon cache for the sddm exists. Any ideas how i can accomplish changing them? Or really I just need the path to them

Thank You
