Radeon 驱动程序不支持受支持的显卡

Radeon 驱动程序不支持受支持的显卡

我的笔记本电脑上有 Intel HD 4000 和 ATI Raedon 8670HD 混合 GPU。但是,Raedon GPU 没有被使用。

规格:

操作系统:Ubuntu 17.04

显卡:

01:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Sun XT [Radeon HD 8670A/8670M/8690M / R5 M330 / M430] (rev ff)

00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)

正如这个问题中提到的,如何安装开源“radeon”驱动程序,当我运行以下命令时:

lspci -k | grep -EA2 'VGA|3D'

这是我得到的:

00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
    DeviceName: Intel(R) Graphics 4000
    Subsystem: Hewlett-Packard Company 3rd Gen Core processor Graphics Controller

如果我运行dmesg | egrep 'drm|radeon',这是输出(部分):

因此,Ubuntu 似乎知道 GPU,但并没有使用它。

其中存在一个名为和 的/usr/share/X11/xorg.conf.d/文件。10-amdgpu.conf10-raedon.conf

答案1

您的radeon驱动程序已安装并正在运行。

要与某些应用程序一起使用它,请运行它DRI_PRIME=1,例如

DRI_PRIME=1 google-chrome

要检查使用了哪个适配器,您可以运行

DRI_PRIME=1 glxinfo | grep OpenGL

运行wuth radeon,和

glxinfo | grep OpenGL

与英特尔一起运行。
