Ubuntu 18 和 TinkPad Yoga 12：挂起功能仅在每隔一段时间起作用，根本不休眠

我放弃了休眠调试，但我希望暂停功能可以正常工作。现在，第一次尝试暂停时，屏幕熄灭，红色 LED 开始闪烁，但 PC 已打开电源，LED 一直闪烁。我必须按下电源按钮才能唤醒它。第二次暂停时，PC 正确暂停。第三次暂停时，情况与第一次相同。依此类推。有人遇到过这种情况并修复过吗？

我编写了一个小型实用程序来自动执行关机、注销、锁定计算机、挂起和休眠。根据需要更改声音，然后编译并更改 chmod u+x 文件名。从终端运行它。我编写了一个小脚本，双击并在终端中运行。

#include <iostream>

using namespace std;

#define bold_on "\e[1m"
#define bold_off "\e[22m"
#define red_on "\033[31m"
#define reset "\033[0m"
#define yellow "\033[33m"
#define b_green "\033[1m\033[32m"
//======================================================================

int main(int argc, char *argv[])
{
 char answer;

  cout << b_green "\n\n Please make you choice? Any other key to quit the program. \n" reset << endl;

  cout << bold_on red_on "      S"  bold_off reset yellow" - Shutdown the Computer"  << endl;
  cout << bold_on red_on "      R"  bold_off reset yellow" - Restart the Computer"<< endl; 
  cout << bold_on red_on "      L"  bold_off reset yellow" - Logoff the Computer"<< endl;
  cout << bold_on red_on "      U"  bold_off reset yellow" - Suspend the Computer"<< endl;  
  cout << bold_on red_on "      H"  bold_off reset yellow" - Hybernate the Computer"<< endl;
  cout << bold_on red_on "      X"  bold_off reset yellow" - Lock the Computer \n\n" red_on;   


  cin >> answer;
    if( answer=='L' ) {
     system("paplay /home/dad/Music/desktop-logout.wav");
     system("cinnamon-session-quit"); 

    } else if( answer=='R' ) {
     system("paplay /home/dad/Music/desktop-logout.wav");
     system("systemctl reboot") ;             

    } else if (answer =='S') { 
     system("paplay /home/dad/Music/desktop-logout.wav");
     system("systemctl poweroff" );

    } else if (answer =='U') { 
     system("paplay /home/dad/Music/desktop-logout.wav");
     system("systemctl suspend");

    } else if (answer =='X') { 
     system("paplay /home/dad/Music/desktop-logout.wav");
     system("cinnamon-screensaver-command -l");

    } else if (answer =='H') { 
     system("paplay /home/dad/Music/desktop-logout.wav");
     system("systemctl hibernate");
     }
 }

这是我桌面上的脚本。

#!/bin/bash
/home/dad/LRS
exit
