静态 tty 屏幕

我的 tty 终端出了问题。启动时，tty 运行良好，但使用大约一小时后，当我切换到 tty 时，系统会提示我输入静态登录提示，而没有闪烁的插入符号。所有 tty 都在顶部显示 tty6。我可以通过盲目输入凭据来登录，甚至可以使用“sudo chvt 7”切换回 gui，但屏幕仍然保持静态。tty7 运行良好，但如果 gui 出现问题，那就太糟糕了。因此，如果我能让它正常工作，那就太好了。任何帮助都将不胜感激。

以下是我的 的内容/etc/default/grub，希望对您有帮助：

# /boot/grub/grub.cfg.

Arch Linux 论坛上有与此问题相关的帖子。他们的问题通过切换到较新的内核得到解决。对我来说也是一样。我必须安装内核 4.6。

这里是针对相同内容的分步指南。

wget http://in4serv.com.br/backup/kernel-4.8.1-stable
sudo chmod +x kernel-4.8.1-stable
sudo ./kernel-4.8.1-stable
sudo reboot

kernel-4.8.1-stable 脚本：

#!/bin/sh
echo "$(tput setaf 3)--- (www.ubuntumaniac.com) | Kernel 4.8.1 Stable will be installed in an `uname -i` system ---$(tput sgr0)"
echo ""
sleep 2
read -p "Press Enter to continue, or abort by pressing CTRL+C" nothing
echo ""
