我已将 Kubuntu 升级到 16.04。从那时起，我无法立即关闭会话。当我选择菜单选项时，一切最初都按预期进行。然而，在我的 HP Probook 4340s 关闭大约 5 秒后，它再次启动，就像再次按下电源按钮一样（但事实并非如此）。
安装laptop-mode-tools没有帮助，grub 设置的修改（“ acpi=noirq/ ”acpi=force和“ apm=power_off”）也没有帮助。BIOS 中的 Wake-on-LAN 设置也已关闭。
当研究journalctl关机和启动程序的日志时也没有发现任何可疑的东西。
我不认为该问题与硬件有关，因为在以前的 (K)Ubuntu 版本中没有出现过该问题。
问题可能出在哪里？我还应该检查什么？
