![当使用 LightDM 时,谁调用 /usr/sbin/lightdm-session](https://linux22.com/image/1173961/%E5%BD%93%E4%BD%BF%E7%94%A8%20LightDM%20%E6%97%B6%EF%BC%8C%E8%B0%81%E8%B0%83%E7%94%A8%20%2Fusr%2Fsbin%2Flightdm-session.png)
我想知道在启动过程中究竟是谁调用了 /usr/sbin/lightdm-session。似乎 LightDM 中某个地方有硬编码,当用户登录并启动新会话时执行此脚本?
答案1
看一眼/lib/systemd/system/lightdm.service
。
答案2
我发现唯一调用它的地方也被注释掉了,所以它在第 11 行不再被调用:
$ cat /usr/lib/lightdm/config-error-dialog.sh

export TEXTDOMAIN=lightdm
. /usr/bin/gettext.sh
PARA1=$(eval_gettext 'Error found when loading $CONFIG_FILE:')
PARA2=$(gettext 'As a result the session will not be configured correctly.
You should fix the problem as soon as feasible.')
TEXT="$PARA1\n\n$(fold -s $ERR)\n\n$PARA2"
if [ -x /usr/bin/kdialog ]; then
TEXT_FILE=$(mktemp --tmpdir config-err-kdialog-XXXXXX)
echo -n "$TEXT" > "$TEXT_FILE"
kdialog --textbox "$TEXT_FILE" 500 300
rm -f "$TEXT_FILE"
elif [ -x /usr/bin/zenity ]; then
zenity --warning --no-wrap --text="$TEXT"
fi
答案3
当lightdm.service
对用户进行身份验证时,将启动并session-wrapper
执行新的会话。您可以在/etc/lightdm/lightdm.conf
或默认:lightdm-session
被执行。
