我买了 Wacom 平板电脑，我认为它可以在 Ubuntu 18.04.5 LTS 上顺利运行。第一次插件后设备一切正常，但重启后机器平板电脑随机运行，就像混乱一样。会发生什么？
我记得之前该命令向我显示了四个项目，而不仅仅是两个：
twaszczyk@ktwtomwasnb:~$ xsetwacom --list devices
Wacom Co.,Ltd. Intuos BT M stylus id: 10 type: STYLUS
Wacom Co.,Ltd. Intuos BT M eraser id: 16 type: ERASER
这是否意味着该命令：
xsetwacom --set "Wacom Co.,Ltd. Intuos BT M stylus" PressureCurve 0 20 80 100
我每次都需要在引导机器上执行吗？是否可以安装已编译的软件包和驱动程序，同时我看到存储库不起作用..
twaszczyk@ktwtomwasnb:~$ sudo add-apt-repository ppa:doctormo/wacom-plus
Wacom sometimes needs updated drivers, these drives will sometimes be better than the ones shipped but you should double and triple check. Please test and send error reports to me (see launchpad profile page) https://launchpad.net/~doctormo
