全新启动/重启后,使用 SynPS/2 Synaptics TouchPad 驱动程序,触控板可正常工作。但是,在合上盖子(导致系统挂起)后,功能会不一致地中断,这种情况很难重现。
故障现象一:双指滚动在启动前有短暂的滞后,并且比平时慢很多。
故障现象二:双指滚动不再起作用,三指滚动起作用。
第二个配置文件确实让我很困惑,因为没有任何设置改变(两指滚动设置为启用,三指滚动则没有)。
下面是 xinput,在盖子关闭事件之前和之后保持不变。

答案1
这真是太尴尬了。虽然我已经完成了完整的安装,sudo apt upgrade
但sudo apt update
实际上只需重新安装我的 synaptics 驱动程序即可解决这个问题。不清楚为什么它不会自动更新,但我对 ubuntu 包管理不太了解。这是修复它的命令:
sudo apt install xserver-xorg-input-synaptics
