笔记本电脑：HP Pavilion 15-ec1058ur 22P97EA（AMD Ryzen 5 4600H 3.0GHz/16384Mb/512Gb SSD/nVidia GeForce GTX 1650 4096Mb）
您好，安装过程中，触摸板完全正常工作，安装后，它完全停止工作。我在网上找到了一个解决方案来更改 /etc/default/grub：
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash psmouse.proto=bare"
GRUB_CMDLINE_LINUX="i8042.reset i8042.nomux i8042.nopnp i8042.noloop"
之后，触摸板可以工作，但双指滚动不起作用。请帮我解决这个问题。

Ubuntu_live.mp4 - 在安装之前以实时模式从闪存驱动器运行 ubuntu，触摸板可以正常工作
Ubuntu_installed.mp4 - Ubuntu 安装后，触摸板仅在更改为 /etc/default/grub 后才起作用，滚动不起作用
