我正在尝试自动校准 Huion 平板电脑,但没有成功。
我有这个输出xinput --list
在普通终端中:
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ USB USB Keyboard id=13 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=16 [slave pointer (2)]
⎜ ↳ Logitech USB Receiver id=14 [slave pointer (2)]
⎜ ↳ HUION PenTablet id=18 [slave pointer (2)]
⎜ ↳ HUION PenTablet id=19 [slave pointer (2)]
⎜ ↳ HUION PenTablet id=20 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Video Bus id=8 [slave keyboard (3)]
↳ Power Button id=9 [slave keyboard (3)]
↳ Sleep Button id=10 [slave keyboard (3)]
↳ Laptop_Integrated_Webcam_2HDM id=11 [slave keyboard (3)]
↳ USB USB Keyboard id=12 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=15 [slave keyboard (3)]
↳ Dell WMI hotkeys id=17 [slave keyboard (3)]
udev log 仅显示相同命令的内容:
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ USB USB Keyboard id=13 [slave pointer (2)]

⎣ Virtual core keyboard id=3 [master keyboard (2)]

id=19
请注意,和的行id=20
缺失了。
我有:

该脚本xinput --list | grep HUION | uniq | awk 'NR==2 …'
尝试捕获id
第二个 HUION 设备(即19
)的,但由于该信息不存在而失败。我该如何解决这个问题?
更新 1
根通过sudo su
给了我同样xinput --list
作为普通用户,但任何校准尝试都没有效果。我需要在 udev shell 脚本调用中切换到我的用户吗?不太优雅…… :(
答案1
问题是,xinput 列表在 udev 规则处理后刷新,后台进程超时无法解决这个问题。解决方案是通过 inotify 触发脚本。原始解决方案和所需的脚本源可以在以下位置找到:https://bbs.archlinux.org/viewtopic.php?pid=1626055#p1626055。
答案2
ACTION=="bind"
我也遇到了同样的问题。我的解决方案是使用而不是 来触发 udev 规则ACTION=="add"
(因为我看到udevadm monitor
这是我连接鼠标时的最后一个操作)
