自从大约一年前在我的笔记本电脑上安装 arch 以来，我一直在努力让 synaptic 正常工作，但它最终完全崩溃了。我需要帮助找出原因，因为过去几个小时我所做的一切都没有解决这个问题。
的输出x输入意识到光标没有移动后立即：
⎡ 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)]
↳ 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)]
↳ HD WebCam id=11 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=12 [slave keyboard (3)]
↳ Acer WMI hotkeys id=13 [slave keyboard (3)]
当我的光标在此之前工作时，有一个条目列出了几个数字并显示“未知”。我很确定那是我的触摸板，但现在不见了。
的内容Xorg.0.log（我认为与我的触摸板相关的部分）

我做的第一件事是禁用 /etc/X11/xorg.conf.d/50-synaptics.conf并重新启动。
现在x输入输出：
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ SYN1B7F:01 06CB:2970 UNKNOWN id=12 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
（我省略了虚拟核心键盘下的部分，因为它们在整个过程中不会改变）。现在之前显示的数字和UNKNOWN又出现了，但是光标还是不动。
环顾四周后，我发现了一个建议我添加的线程
i8042.nopnp i8042.nomux=1 i8042.reset
通过引导加载程序设置到我的内核。我使用 systemd-boot，并将这些设置添加到 /boot/loader/entries/arch.conf 中。重启后xinput还是一样，光标还是不动。
我继续搜索，发现另一个线程提到将 i2c_hid 驱动程序列入黑名单。我想我会尝试一下，所以我在 /etc/modprobe.d 中创建了一个包含以下内容的conf文件
blacklist i2c_hid
重新启动后，x输入再次有不同的输出：
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=13 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
xinput 输出一些合理的内容而不是 UNKNOWN 似乎很有希望，但光标仍然不会移动。
此时，我重新激活了/etc/X11/xorg.conf.d/50-synaptics.conf并重新启动。
重新启动后，x输入返回到不显示任何触摸板，并且光标仍然不移动。
⎡ 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)]
我查看了 50-synaptics.conf，认为其中可能存在某种错误，但经过仔细检查后我找不到错误。
Section "InputClass"
Identifier "touchpad catchall"
Driver "synaptics"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
Option "TouchpadOff" "0"
Option "MaxTapTime" "0" #disables tapping

Option "ClickPad" "0"
Option "VertTwoFingerScroll" "on"

Option "TapButton2" "2"
Option "TapButton3" "3"
EndSection
我尝试了几种不同的更改组合，例如删除 i8042 选项，但将 i2c_hid 列入黑名单，但我尝试的任何操作都没有产生任何显着差异，并且光标仍然无法移动。
至此，我开始写这个问题。如果我遗漏了任何重要的日志文件或任何内容，请告诉我，我会发布它们。请帮帮我。这开始让我发疯。
答案1
我今天也遇到了类似的问题。关于50-synaptics.conf我只是将其删除/etc/X11/xorg.conf.d/并重新启动systemctl stop/start lxdm.service（budgie 桌面），一切都重新开始工作。
