自从我安装Ubuntu 16.04后,我的笔记本电脑(HP Probook 450 G2)出现了从挂起状态唤醒的问题。很少能设法从暂停中正确唤醒,但大多数情况下,屏幕要么保持黑屏,要么打开,并在2或3秒后完全冻结,然后在这两种情况下风扇活动都变大了。我不能切换到tty外壳,或者除了按住电源按钮来切断电源以外,无法执行其他任何操作。
我尝试了以下不同的解决方案,例如禁用USB Legacy,将acpi_backlight = vendor acpi_osi ='!Windows 2013'acpi_osi ='!Windows 2012'添加到GRUB_CMDLINE_LINUX_DEFAULT,但没有任何效果。
我昨天切换到Linux Mint只是为了测试那里是否有问题,但问题仍然存在。这是/var/log/kern.log的输出,该输出显示了我上一个会话的最新消息。
