Estou instalando o Lubuntu em desktops antigos, uma mistura de arquiteturas de 64 e 32 bits. Instalei o Lubuntu 20.04 nos PCs de 64 bits e gostei da UI, e gostaria do mesmo em 32 bits onde apenas o 18.04 pode ser instalado. Como o Lubuntu abandonou o LXCE desde 18.10 para o lxqt, acho que preciso instalar o lxqt. Mas não posso fazer nenhuma alteração na UI: o programa lightDM GTK+ Greeter supostamente permite alterar o tema e os ícones, mas nenhuma das opções possíveis, sejam as instaladas com o Lubuntu ou outras que instalei, aparece, permanece sempre com o tema padrão e ícone. Aqui está o que o lightdm --show-configcomando mostra:
