我在 Ubuntu 20.04 中的图形输入板 (Huion WH1409) 出现问题。它以前在 Ubuntu 中运行良好,开箱即用,基本运行良好,无需安装驱动程序或配置。
现在它只是没有输入。它显示得很好,并且 uclogic 驱动程序似乎正确加载。
这是插入平板电脑时的 dmesg 输出:

这是相关部分xinput --list

xev
不显示笔或笔或数位板上的任何按钮的输出。
我已经确认这款平板电脑在 Windows 中运行良好,而且在以前的 ubuntu 版本中也确实可以正常运行。
编辑:我还想指出,我使用 xorg 将平板电脑设置为使用以前也可以使用的 wacom 驱动程序。发生同样的事情,加载驱动程序正常,显示在 xsetwacom 中,但没有收到任何输入。
