Avell W1513 触摸板不工作:引脚不能在 Ubuntu 18.04 上用作 irq

Avell W1513 触摸板不工作:引脚不能在 Ubuntu 18.04 上用作 irq

我有一台 Avell W1513 笔记本电脑,触摸板无法使用。它不会显示在 xinput 列表中:

⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]

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

看起来内核不支持它,但是启动时出现一条错误消息,这可能是问题的线索:

Jun  7 09:17:34 shrek4 kernel: [    3.615709] cannonlake-pinctrl INT3450:00: pin 263 cannot be used as IRQ

不确定生成这些消息的设备是否是触摸板本身,但在此主题在类似的触摸板问题上也出现了相同的消息。

已经尝试在开启 acpi 的情况下进行启动,i8402 支持内核 4.17 和 synaptics_i2c模块(加上黑名单i2c_hid),但没有成功。

由于它不是一个常见的品牌,因此规格如下:

唯一的选择是等待内核支持它;或者这里有人能想到一个可解决的问题(而不是缺乏支持)吗?

谢谢你!

在 Ubuntu 19.04 中,触摸板运行良好 - 如果您遇到同样的问题,则值得更新。

答案2

Avell 的供应商告诉我他们不使用 Clevo 的零件。不过,我发现一些来自同方(一家 ODM 制造商)的笔记本电脑可能是向 Avell 出售零件的笔记本。至少,它们的外壳和规格看起来是一样的。

话虽如此,您可以尝试通过搜索类似的项目来查找与 Linux 相关的信息。我发现的是这样的:

看看 Youtube 评论(就像 Avell 从一些公司那里买的一样,他们从同方购买,然后贴上自己的品牌转售)。它看起来就像 Avell 笔记本。

有问题的型号是同方 GJ5CN6E,但他们还有许多其他型号,也许您的就是其中之一。
