xautolock:如何根据用户活动自动解锁?

xautolock:如何根据用户活动自动解锁?

我需要在用户不活动一段时间后运行脚本。为此,我使用了很棒的程序xautolock

现在,我还需要当活动恢复时运行另一个脚本(例如移动鼠标或按下某个键)。

我怎么做?任何类型的反 xautolock 吗? xautoUNlock?

或者,也许,任何其他简单的如何抓住“闲散”停止的那一刻?

答案1

我编写了以下脚本来检查空闲状态并相应地使用 systemd-logind 更新会话空闲状态。 (通常这将由会话管理器完成,但我不运行会话管理器。)这让 systemd 自动将系统置于睡眠状态(基于和IdleAction),在确定系统是否处于运行状态时同时考虑 X11 和 ssh 登录。闲置的。部分基于IdleActionSec/etc/systemd/logind.conf

您可以修改 login1_idle 类来运行您想要的任何脚本。

#!/usr/bin/python

import ctypes
import os
import dbus
import time

# Timing parameters, in s
idle_threshold = 60 # Amount of idle time required to consider things truly idle
check_interval = 50 # How often to check the X server idle indication

class login1_idle:
  def __init__(self):
    self.flag = 0
    bus = dbus.SystemBus()
    seat = bus.get_object('org.freedesktop.login1',
                          '/org/freedesktop/login1/seat/'
                           + os.environ['XDG_SEAT'])
    active_session = seat.Get('org.freedesktop.login1.Seat',
                              'ActiveSession',
                              dbus_interface='org.freedesktop.DBus.Properties')
    session_obj_path = active_session[1]
    self.session = bus.get_object('org.freedesktop.login1', session_obj_path);

  def on_busy(self):
    self.flag = 0
    self.session.SetIdleHint(False,
                             dbus_interface='org.freedesktop.login1.Session')

  def on_idle(self):
    self.flag = 1
    self.session.SetIdleHint(True,
                             dbus_interface='org.freedesktop.login1.Session')

class XScreenSaverInfo(ctypes.Structure):
  """ typedef struct { ... } XScreenSaverInfo; """
  _fields_ = [('window',      ctypes.c_ulong), # screen saver window
              ('state',       ctypes.c_int),   # off,on,disabled
              ('kind',        ctypes.c_int),   # blanked,internal,external
              ('since',       ctypes.c_ulong), # milliseconds
              ('idle',        ctypes.c_ulong), # milliseconds
              ('event_mask',  ctypes.c_ulong)] # events

xlib = ctypes.cdll.LoadLibrary('libX11.so')
display = xlib.XOpenDisplay(os.environ['DISPLAY'])
xss = ctypes.cdll.LoadLibrary('libXss.so.1')
xss.XScreenSaverAllocInfo.restype = ctypes.POINTER(XScreenSaverInfo)
xssinfo = xss.XScreenSaverAllocInfo()

idle = login1_idle()

while True:
  xss.XScreenSaverQueryInfo(display, xlib.XDefaultRootWindow(display), xssinfo)

  #print "idle: %d ms" % xssinfo.contents.idle

  if xssinfo.contents.idle > idle_threshold * 1000 and not idle.flag:
    print time.strftime('%c') + " doing on_idle"
    idle.on_idle()

  elif xssinfo.contents.idle < idle_threshold * 1000 and idle.flag:
    print time.strftime('%c') + " doing on_busy"
    idle.on_busy()

  #print idle.session.Get('org.freedesktop.login1.Session',
  #                       'IdleHint',
  #                       dbus_interface='org.freedesktop.DBus.Properties')

  time.sleep(check_interval)

C/bash 实现的另一个类似问题是系统空闲时和再次活动时运行命令
