openSUSE에서 GNOME을 KDE로 교체

openSUSE Leap 15저는 GNOME 데스크탑 환경을 사용하고 있었습니다 . KDE 플라즈마를 이런 식으로 설치했습니다:

https://en.opensuse.org/SDB:KDE_install

KDE Plasma를 설치한 후 다음 지침에 따라 Leap 15를 Tumbleweed로 업그레이드했습니다.

https://en.opensuse.org/openSUSE:Tumbleweed_upgrade

이 파일을 편집하고 다음 Gdm으로 대체했습니다 .KdmGnomePlasma5

me@linux-iwyn:~> sudo vim /etc/sysconfig/windowmanager 
me@linux-iwyn:~> sudo vim /etc/sysconfig/displaymanager 

이제 openSUSE TumbleweedKDE Plasma 데스크탑 환경을 사용하여 로그인했습니다. 그러나 나는 gdm 및 gnome 관련 항목이 여전히 내 시스템 전체에 흩어져 있다는 것을 관찰했습니다.

Gnome/Gdm을 완전히 제거하는 방법을 알고 싶습니다.
