我跟着这手册,希望在重新启动后,肉桂的软件渲染模式能够停止在我的屏幕上烦人。但没有帮助。
我做了:
$ cat /etc/apt/sources.list
deb http://httpredir.debian.org/debian/ stretch main contrib non-free
$ sudo apt-get install firmware-linux-nonfree libgl1-mesa-dri xserver-xorg-video-ati
Reading package lists... Done
Building dependency tree
Reading state information... Done
libgl1-mesa-dri is already the newest version (13.0.6-1+b2).
xserver-xorg-video-ati is already the newest version (1:7.8.0-1+b1).
firmware-linux-nonfree is already the newest version (20161130-3).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
$ xrandr --listproviders
Providers: number : 0
重启后没有任何改变。我的分辨率较低,并且软件渲染模式处于打开状态。
UPD
xserver-xorg-video-radeon
也已经安装了

答案1
您将需要从向后移植更新内核、固件、显卡和台面。看https://www.guyrutenberg.com/2018/11/01/getting-radeon-rx-550-to-work-under-debian-stretch/
答案2
我会使用 radeon 驱动程序作为 radeon。
sudo apt-get install xserver-xorg-video-radeon
当然,曾经有专有驱动程序 fglrx,但我不确定它们是否保持最新。上周末尝试过,它们似乎已经严重过时了。
