USB设备断开/触摸屏关闭
USB设备断开/触摸屏关闭
提问于 2019-10-01 18:06:56
我这里有一辆东芝Z20T-C敞篷车，运行Ubuntu 19.04，内核5.0.0-29。在几天/几周的时间里，触屏、键盘背光和可拆键盘底座(底部)中的usb端口几乎在引导到桌面后立即停止工作。触摸屏和键盘继续工作。所有设备和端口都在BIOS菜单中工作，因此我将排除硬件缺陷。当我分离/重新连接船坞时，键盘灯会短暂闪烁，触控板工作几秒钟，然后再次死亡。我已经尝试关闭usbcore的自动挂起(内核引导参数中的usbcore.auto悬架=-1，并更新grub)。这在屏幕关闭之前是有帮助的。之后触控板又死了。此外，还尝试切换电源设置的一些usb设备在电源顶部，但这没有帮助。但我不确定我的目标是正确的设备。
当断开/重新连接码头时，dmesg告诉我：

编辑1:我使用了"udevadm监视器“来检查设备死后会发生什么。它打印：

编辑2:我尝试过在内核引导模式参数中添加"acpi=off“，然后回滚到内核5.0.0-13，但是它没有改变任何东西。我还尝试添加一个UDEV规则文件“/etc/udev/ rule es.d/99-powerSave.Rule”：
ACTION=="add", SUBSYSTEM=="usb", ATTR{power/control}="on"
ACTION=="add", SUBSYSTEM=="usb", ATTR{power/autosuspend}="0"
ACTION=="add", SUBSYSTEM=="usb", ATTR{power/autosuspend_delay_ms}="-1"
ACTION=="add", SUBSYSTEM=="usb", ATTR{busnum}=="1", ATTR{power/control}="on"
ACTION=="add", SUBSYSTEM=="usb", ATTR{busnum}=="2", ATTR{power/control}="on"但这也没什么用。我现在还不知道下一步该做什么。
编辑3:我已经尝试了内核版本4.18.20，5.0.21和5.2.21，没有任何成功。可能是udev / acpi /司机的问题，但我不知道该去哪找.

在我的例子中，它毕竟是一个硬件缺陷。在某个时候，甚至连键盘都死了，所以我更换了整个键盘/码头部分。现在一切都正常了，所以这不是Linux的问题.

此回答有许多USB自动断电设置可检查：
经过几天的挣扎，我终于在Ubuntu17.10上找到了解决方案。希望这对所有与D6000码头有问题的人都适用。下面的格式是标记格式(延迟转换格式)

禁用USB AutoSuspend
sudo gedit /etc/default/tlp并将下面的值从1更改为0
USB_AUTOSUSPEND=0sudo gedit /etc/udev/rules.d/01-usb-dock.rules。这将创建一个新文件。

sudo gedit /etc/pulse/default.pa。注释掉下面所示的行。
### Automatically suspend sinks/sources that become idle for too long

通过在机器打开时按下F12键启动BIOS。在Power Management >> USB Wake Support下，取消选中这两个框。
