Linux Mint 17 Xfce で xscreensaver を gnome-screensaver に変更したときのメモ。
Settings Manager にスクリーンセーバの切り替え項目はなく、/usr/bin/xflock4
が light-locker-command
、xscreensaver-command
、gnome-screensaver-command
の優先順位で自動的にスクリーンセーバコマンドを検出するようになっている。

xscreensaver を削除して gnome-screensaver を新たにインストールする。xscreensaver の方は xscreensaver-data などのパッケージもあるので不要それらも削除する。
sudo apt-get remove xscreensaver
sudo apt-get install gnome-screensaver
