无法彻底清除fglrx

Question

我已经得到14.04，并安装了专有的AMD催化剂14.6使用生成分配特定的驱动程序包选项，在安装程序说明中描述。

现在我想更改为mesa-vdpau-drivers，但不能从我的系统中完全清除fglrx。

到目前为止，我尝试的是我在几个HowTos中找到的，基本上可以归结为运行以下命令：

sudo apt-get remove --purge fglrx fglrx-amdcccle fglrx-dev
sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon
sudo apt-get install xserver-xorg-video-ati
sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.backup
sudo rm -rf /etc/ati

但是，在我的dmesg输出中，仍然可以看到以下几行：

[   58.779902] fglrx: module license 'Proprietary. (C) 2002 - ATI Technologies, Starnberg, GERMANY' taints kernel.
[   58.779916] Disabling lock debugging due to kernel taint
[   58.798511] fglrx: module verification failed: signature and/or  required key missing - tainting kernel

[   58.825577] <6>[fglrx] module loaded - fglrx 14.10.2 [May  5 2014] with 1 minors

完整的dmesg输出以这个巴斯特宾表示。

如果能提供任何帮助..。

Answer 1

在之前安装了fglrx专有驱动程序之后，我在试图正确运行Radeon开源驱动程序时遇到了同样的问题。

事实上，我对Radeon开源驱动程序的需求是与xbmc论坛上的这篇文章链接的：带有vdpau的Linux - Radeon (howto)。

我删除了fglrx驱动程序，并在这个Ubuntu wiki页面之后安装了一个开源驱动程序

但我在XBMC上的视频撕裂仍然有问题。(XBMC中没有硬件加速，CPU使用率为180% )

我仔细地阅读了/var/log/Xorg.0.log文件的我用的那篇文章版本和系统上的版本。我注意到不同之处是：

LoadModule: "ati"
Warning, couldn't open module ati
UnloadModule: "ati"
Unloading ati
Failed to load module "ati" (module does not exist, 0)

所以ATI司机没有被使用..。而fglrx也不是

LoadModule: "fglrx"
Warning, couldn't open module fglrx
UnloadModule: "fglrx"
Unloading fglrx
Failed to load module "fglrx" (module does not exist, 0)

Xorg没有考虑两个驱动程序"fglrx“(因为已删除)或"ATI”。原因可能是"fglrx“没有被完全删除，"ATI”Radeon没有完全安装。

所以我再次运行了安装程序

sudo apt-get install xserver-xorg-video-ati

魔法来了！现在在我的/var/log/Xorg.0.log文件中：

和XBMC:不再有视频撕裂和5%的CPU使用率:硬件加速工作！
