我的 KDE 17.04 出现了问题。它经常崩溃，但我不知道原因。今天几个小时内，它已经崩溃了两次。有时键盘能用，但鼠标不行，有时什么都不能用，没有键盘，没有鼠标。有人有同样的问题吗？你知道该如何解决或从哪里开始检查吗？
更新
除了偶尔崩溃外，其他都运行良好
的结果sudo dmidecode

因此，根据我们的讨论，这是升级到 17.04 的问题，问题太多，症状千差万别，除了重新安装之外，没有 100% 的解决方法。抱歉。
继续并按照我的指南进行操作： 操作系统升级后，系统在登录界面冻结
我建议使用“格式化/擦除磁盘并安装 kubuntu”选项或“其他选项”，如果您不希望它尝试使用旧的 grub 。
