![Ubuntu 20.04 中的 AMD Radeon HD 8790M 驱动程序问题](https://linux22.com/image/1188125/Ubuntu%2020.04%20%E4%B8%AD%E7%9A%84%20AMD%20Radeon%20HD%208790M%20%E9%A9%B1%E5%8A%A8%E7%A8%8B%E5%BA%8F%E9%97%AE%E9%A2%98.png)
我已经有好几年没有使用过内置的笔记本电脑显卡了,它一直都很好,但现在在 FreeCAD 中做一些建模,它的速度非常慢,所以我真的非常希望我的显卡能正常工作。
我的显卡未被 Ubuntu 20.04 使用:

我认为问题的一部分是该卡是一个FirePro W4170M
但被 Linux 作为 拾取Radeon HD 8790M
。
答案1
删除radeon.modeset=0
并/etc/default/grub
运行
sudo update-grub
这将解决问题。
但您需要DRI_PRIME=1
使用 AMD GPU。
您可以通过运行以下命令检查 AMD GPU 是否正常工作:
DRI_PRIME=1 glxinfo | grep OpenGL
要修复radeon
错误,请radeon.runpm=0
像这样添加到 grub 中
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.runpm=0"
并再次运行sudo update-grub
并重新启动。
现在,如果您想在 AMD GPU 上运行程序,请使用 启动它DRI_PRIME=1
。例如:
DRI_PRIME=1 firefox
您可以将其添加DRI_PRIME=1
到程序.desktop
文件中,以便永久使用。
如果要在 AMD 上运行所有程序,请添加DRI_PRIME=1
到文件末尾/etc/environment
。
