I got some problems when i tried to install LightDM to my netrunner installation. When I tried to install the lightdm packages i got the following message (original error msg is in German so i give a rough translation):
lightdm and sddm are in conflict (displamanager), remove sddm?
When I try to remove sddm I get a message telling me that several packages depend on the package sddm, among them the package netrunnerarch-default-settings. After a short look into the purpose of that package (it contains the default configuration for several kde applications) I didn’t dare to go any further :).
Does anyone have any idea what i can do to get LightDM on my system? Do i overestimate the importance of the package netrunnerarch-default-settings? Or do I have to open an error report and ask the developers to remove the dependency of a central component to SDDM ?
SDDM is replacing KDM and will be the default for Plasma 5 once it becomes our default desktop as the lock screen needs it to work properly, just a FYI.
Anyway, this is a problem in Netrunner Rolling at the moment, the Netrunner development team need to work on their netrunner specific packages so they don’t conflict with the way a Rolling Release model is supposed to work.
Then i used this page from the manjaro wiki to configure lightdm: https://wiki.manjaro.org/index.php?title=Install_Display_Managers
Attention: The entries for the lighdm.conf file as described in that page contain a nasty little bug. If you enter the comments as given in the example, lightdm will add some space characters to the filename it searches for further configuration, resulting in a “config file not found error”. I simply dropped the comments and everything worked right.
I set the user-session parameter to “kde-plasma”.
If anyone else as crazy as me wants to do the same, that might be helpful.
