Don't confuse DM (Display Manager) with DE (Desktop Environment). The DM is the thing that presents the login GUI and then invokes a DE, which may be KDE, Gnome, Xfce etc. The preferred DM for KDE is SDDM, but it can invoke the Gnome DE if you like. Gnome normally uses GDM and the same applies in reverse. If switching between DMs then yes, you do need to log out and run a script, but there's normally no need. You can switch between DEs from the login screen. Plasma is not the whole DE. You can restart it at any time without logging out if you have a working terminal emulator. poc -- _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
