gnome-flashback

如何安裝

執行下面指令，安裝「gnome-session-flashback」。

sudo apt-get install gnome-session-flashback

也會連同安裝「gnome-panel」和「metacity」。

關於「WM」，

除了可以搭配採用「metacity」，

也可以改搭配採用「compiz」

執行下面指令，安裝「compiz」

sudo apt-get install compiz

執行下面指令，安裝「compizconfig-settings-manager」

sudo apt-get install compizconfig-settings-manager

關於「compizconfig-settings-manager」這個「圖形介面設定工具」，可以用來設定「compiz」。

另外「gnome-flashback」除了原本的「gnome-control-center」這個「圖形介面設定工具」，

也可以安裝「gnome-tweaks」這個「圖形介面設定工具」。

而我比較慣用的是採用指令的方式來設定，

主要是透過「gsettings」搭配「dconf」來設定。

相關範例，可以參考「Ubuntu 微調」。

gnome-panel layout

範例

執行

ls -1 /usr/share/gnome-panel/layouts

顯示

default.layout
gnome-flashback.layout
ubuntu.layout

從「/usr/share/gnome-panel/layouts」這個資料夾，

可以找出有那些「layout」可以採用。

執行下面指令，清空相關設定。

dconf reset -f /org/gnome/gnome-panel/

執行下面指令，設定採用「layout」。

gsettings set org.gnome.gnome-panel.general default-layout "ubuntu"

重新啟動「gnome-panel」，就會採用新的「layout」。

gnome-panel --replace &

執行下面指令，可以看到相關的設定

gsettings list-recursively | grep org.gnome.gnome-panel

或是執行

dconf dump /org/gnome/gnome-panel/
