笔记本设置仅外接屏幕显示后，窗口十分卡顿

syblue · 2020-09-15 00:36:02

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。

遇见同样的问题，但我并未使用mwhd. 笔记本配置为3060,采用NVIDIA闭源驱动。在hybrid模式下，用hdmi输出（连接到3060）的外接显示器如果是“仅外接显示”输出会非常卡顿，如果同时开启笔记本内屏就正常了。目前我的解决方案是 https://wiki.archlinux.org/title/NVIDIA … phics_only 设置采用NVIDIA显卡渲染xorg.

同样的问题，intel 与 nvidia 双显卡笔记本，使用 nvidia 驱动外接显示器时只有在移动光标是外接显示器才刷新。
解决方案如下：

我的也是这种情况，显卡是1050，之前解决过这个问题，我记得是用一个软件模拟的独显直连然后就解决了
