进入 TTY 时,我可以按 alt+F7 返回 xfce 而不会出现任何问题,但我无法执行任何其他操作。
注意:我知道板载 USB 控制器很差。它真的很难识别插入的设备。我只在转向 Linux 前几周才添加了一个 PCI 控制器。

答案1
我遇到了同样的问题,解决方案建议这里解决了我的问题。我只需拔掉笔记本电脑的电源插头并取出电池,让电量完全耗尽,然后重新启动电脑,一切就都正常了。在选择更复杂的选项之前,值得尝试一下。
答案2
对于仍然遇到此问题的人来说,这绝对是 USB 控制器的问题。我在 Ubuntu 和 Fedora 上都遇到过这种情况。
更换了 USB 控制器后,噗的一声,它就消失了。
