我在启动 Ubuntu 时遇到了一些问题。尝试重新启动一段时间后,我最终打开了 4.4.0-31 恢复模式。在启动恢复模式时,系统提示/dev/ubuntu-gnome-vg
需要fsck
手动操作。
当这种情况发生时,计算机的触摸屏就会反复连接和断开连接。
屏幕上显示的内容如下:
usb 2-7: new full-speed USB device number 42 using using xchi_hcd
usb 2-7: New USB device found, idVendor=04f3, idproduct=016f
usb 2-7: New USB device strings: Mfr=4, Product =14, SerialNumber=0
usb 2-7: Product: Touchscreen
usb 2-7: Manufacturer: ELAN
usb 2-7: ep 0x2 - rounding interval to 64 microframes, ep desc
says 80 microframes
usb 2-7: USB disconnect, device number 42.
然后重复此操作,设备编号为 43。
我该如何阻止这种情况,以便我可以真正尝试修复磁盘上的问题。另外,如果你们对 /dev/ubuntu-gnome-vg 需要进行 fsck 有什么建议,那就太好了。

这看起来与损坏的 USB 电缆或端口非常相似。我可以肯定地说,因为我正在使用这样的设备:每次我触摸 USB 集线器的电缆时,我都会在/var/log/syslog
墙上看到关于(dis)连接,并增加设备号;并且连接的鼠标会重置其灵敏度。
仅供记录,这是我的日志的一个例子:

答案2
暂时断开触摸屏设备与 USB 端口的连接。然后从 GRUB 菜单启动计算机进入恢复模式,选择 ROOT,然后输入sudo fsck -f /dev/ubuntu-gnome-vg。让我们知道这是如何运作的。干杯,Al
答案3
电缆故障可能会导致这种情况。
也可能是电源问题。自从换成有源 USB 集线器后,我的一些 USB 拇指驱动器使用起来就好多了。
