[SOLVED] How to get default SDDM theme back?

[dowkf]

Hi,
All I did was changing mouse pointer theme in SDDM configuration and clicking Apply. After this the SDDM was a white screen with almost nothing visible (I could login though). How can I get default Kubuntu 18.04's SDDM theme back? I've tried few themes from repository but they don't look as good as the default one.

The KDE SDDM configuration module is editing /etc/sddm.conf

[Autologin]
Relogin=false
Session=
User=

[General]
HaltCommand=
RebootCommand=

[Theme]
Current=breeze
CursorTheme=breeze_cursors

[Users]
MaximumUid=65000
MinimumUid=1000

Does your config file has the "Current=breeze" line ?

and the theme configuration (breeze): /usr/share/sddm/themes/breeze/theme.conf.user

[General]
background=someimage.jpg
type=image

Does your /usr/share/sddm/themes/breeze/ directory have the "someimage.jpg" file ?



You could test your SDDM theming with the command:

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

$ sddm-greeter --help

Yes, I had to find and add the background file because it wasn't set. It's strange because all I did was changing mouse theme. Thank you for your help.
