最近购买了戴尔 Latitude 5495,直接安装了 Ubuntu。立即开始注意到一些小问题:
- 鼠标指针会随机冻结,就像冻结一样,需要重新启动才能修复。
- 两指滚动根本不起作用。
- 我试着回到突触
sudo apt install xserver-xorg-input-synaptics; sudo apt remove xserver-xorg-input-libinput
删除 libinput 后,无法让键盘和触摸板再次工作。所以再次格式化(幸运的是它是一个全新的安装)
键盘再次工作,但两指滚动仍然无法工作。

我知道这个触摸板支持两指滚动,因为它在 Windows 中工作。
不知道如何让两指滚动工作。对于 Ryzen 5 Pro 2500U 和最新的 Ubuntu 内核,还有我应该注意的已知问题列表吗?
