Currently, I have Plasma desktop. I want to install Xfce with Manjaro theming, and apply it to my existing user account. What to do, so the Manjaro theming will apply to my existing user account? I ran the commands posted below, rebooted, and logged in under Xfce desktop, but the Manjaro theming did not show on the desktop. I saw the mouse and generic Xfce theme, so I rolled my system back.
When I first tried to run
sudo pacman -S manjaro-xfce-gtk3-settings manjaro-settings-manager
it failed with an error message that a certain file in /usr already exists. So I deleted that file (don’t remember its name) from root, and ran the above command again. The installation succeeded, but no Manjaro theme.
sudo pacman -S xfce4-gtk3 xfce4-goodies xfce4-terminal network-manager-applet xfce4-notifyd-gtk3 xfce4-whiskermenu-plugin-gtk3 tumbler engrampa sudo pacman -S lightdm lightdm-gtk-greeter lightdm-gtk-greeter-settings sudo systemctl enable lightdm.service --force sudo pacman -S manjaro-xfce-gtk3-settings manjaro-settings-manager
