以下是我的Arch
linux终端上lscpci命令的输出.我使用的是联想G 50-70笔记本电脑.

RTL8723BE PCIe Wireless Network Adapter 03:00.0 Display controller: Advanced Micro Devices,Inc. [AMD/ATI] Sun LE [Radeon HD 8550M / R5 M230] 我想知道为什么我的VGA兼容控制器和显示控制器显示不同的输出? 何时以及为何使用它们? 有没有办法检查哪个应用程序使用哪个图形控制器? 编辑1: [code_master5@BitBox node-express]$grep LoadModule /var/log/Xorg.0.log [ 17.105] (II) LoadModule: "glx" [ 17.279] (II) LoadModule: "intel" [ 17.343] (II) LoadModule: "modesetting" [ 17.348] (II) LoadModule: "fbdev" [ 17.349] (II) LoadModule: "vesa" [ 17.374] (II) LoadModule: "dri3" [ 17.374] (II) LoadModule: "dri2" [ 17.374] (II) LoadModule: "present" [ 17.895] (II) LoadModule: "libinput" [ 18.144] (II) LoadModule: "synaptics" 但第二个不起作用…… [code_master5@BitBox node-express]$grep Driver /etc/X11/xorg.conf grep: /etc/X11/xorg.conf: No such file or directory 解决方法
它取决于适配器固件如何向PCI总线声明自己.
原因可能是因为在Optimus双图形系统中. 您可以运行此命令以找出系统当前使用的图形控制器: grep LoadModule /var/log/Xorg.0.log grep Driver /etc/X11/xorg.conf (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
