不久前，我将 Toshiba Satellite C55-B5356 升级到了 Ubuntu 18.04，但触摸板一直有问题。不过我通常使用 USB 鼠标，所以到目前为止，我从未需要修复此问题。不过最近我决定开始备份硬盘，并购买了一个 USB 工具来连接另一个驱动器以复制我的文件。不幸的是，由于其他 USB 端口都已损坏，我只有一个可用的 USB 端口，所以我现在需要触摸板才能工作。我尝试了一些方法，例如安装 xserver-xorg-synaptics 包，但在我进一步搞砸事情之前，我想咨询其他人。
我目前的情况是：
- 触摸板在 Ubuntu 中不响应任何输入。虽然它在 BIOS 中可以工作
- 查看设置确实会显示触摸板部分，并且选择器开关设置为开启
- 的输出
cat /proc/bus/input/devices是：
I: Bus=0011 Vendor=0002 Product=0007 Version=01b1
N: Name="SynPS/2 Synaptics TouchPad"
P: Phys=isa0060/serio1/input0
S: Sysfs=/devices/platform/i8042/serio1/input/input5
U: Uniq=
H: Handlers=mouse1 event5
B: PROP=9
B: EV=b
B: KEY=6420 30000 0 0 0 0
B: ABS=260800011000003
- 输出也是

根据我所读到的内容，我的问题似乎与驱动程序有关，因为触摸板似乎已被识别，尽管我以前从未处理过这个问题，所以我不确定如何继续。是什么导致我的触摸板无法正常工作？
