笔记本设置仅外接屏幕显示后,窗口十分卡顿

笔记本型号

Dell G5 5590
显卡为GTX1650的版本

问题说明

在安装完archlinux后无法外接屏幕,表现是能识别外接屏幕,能设置双屏,但是扩展屏幕没有任何内容,只有鼠标,能将窗口拖过去但是无法显示。
在尝试包括但不限于“更换开/闭源驱动”、“安装nvidia-prime”、“配置xorg.conf”后均无果。
突发奇想,在AUR源中下载了mhwd,使用mhwd安装了video-hybrid-intel-nvidia-dkms-prime-render-offloading驱动,无法双屏的问题奇迹般解决。

这时出现了第二个问题,当笔记本设置为“仅笔记本屏幕”、“向左拓展”、“向右拓展”时,没有任何异常,但当设置为“仅拓展屏幕”时,一切都开始卡顿(除了鼠标)。当然,此时画面仅在外接屏幕显示,切换画面是没有问题的。
目前尝试了KDE与xfce4,表现均为上述效果。

可能会需要
