如何更改访客会话警报消息

当访客用户登录时，他们会收到一条警告消息，内容为“此访客会话期间创建的所有数据...”。我想更改该消息的文本，但找不到该文本的来源。我知道 Zenity 用于显示它，但我找不到该文本的来源。

答案1

我建议你创建自己的对话框，并禁用默认对话框。请参阅本教程寻求指导。

编辑（示例代码）：

$ cat /etc/guest-session/auto.sh
TITLE='Temporary Guest Session'
TEXT="Hello my Dear Guest. Hope you'll enjoy Ubuntu!"
{ sleep 4; zenity --warning --no-wrap --title="$TITLE" --text="$TEXT"; } &

答案2

该文本的来源是以下脚本：

/usr/lib/lightdm/guest-session-auto.sh

您必须修改它才能更改消息，因为无法自定义 $TEXT 设置：

    TEXT=$(gettext 'All data created during this guest session will be deleted

    para2=$(gettext 'Another alternative is to save files in the

    test -w /var/guest-data && TEXT="$TEXT\n\n$para2"
}
test -f "$HOME"/.skip-guest-warning-dialog || {
    if [ "$KDE_FULL_SESSION" = true ] && [ -x /usr/bin/kdialog ]; then
        dialog_content
        TEXT_FILE="$HOME"/.guest-session-kdialog
        echo -n "$TEXT" > $TEXT_FILE
        {
            # Sleep to wait for the the info dialog to start.
            # This way the window will likely become focused.
            sleep $DIALOG_SLEEP
            kdialog --title "$TITLE" --textbox $TEXT_FILE 450 250
            rm -f $TEXT_FILE
        } &
    elif [ -x /usr/bin/zenity ]; then
        dialog_content
        {
            # Sleep to wait for the the info dialog to start.
            # This way the window will likely become focused.
            sleep $DIALOG_SLEEP
            zenity --warning --no-wrap --title="$TITLE" --text="$TEXT"
        } &
    fi
}

# run possible local startup commands
test -f /etc/guest-session/auto.sh && . /etc/guest-session/auto.sh
