amd gpu 但显示在英特尔集成显卡上

在我的 Ubuntu 12.04 上，我将显示器连接到板载英特尔显卡。我想将我的 ati radeon 6770 用于 opencl 任务（例如比特币挖掘）。

到目前为止，我无法弄清楚如何让 ati 驱动程序工作。当调用 "aticonfig --initial -f" 时，它总是写入一个新的 xorg.conf 忽略英特尔图形。在启动时，它仅在我将显示器连接到 ati 卡时工作。

所以我手动篡改了 xorg.conf 并得到了这个：

Section "ServerLayout"
    Identifier     "Default Monitor"
    Screen      0  "myscreen" 0 0
    Screen      1  "deadscreen" RightOf "myscreen"

我认为这可能是正确的方法，因为我看到 X 尝试在 /var/log/Xorg.0.log 中启动两个驱动程序。但是 fglrx 驱动程序似乎崩溃了（xorg.0.log 结尾）：

如果有人可以提示我如何在使用集成显卡进行显示时配置我的 ATI 卡，我会非常高兴。

更新

我使用了大部分 jjhughes57 配置并在英特尔上成功启动了 X 服务器（但有趣的是，键盘布局发生了变化）。

不幸的是，第二个 X 服务器 (fglrx) 没有完全启动。它在启动后立即关闭>

感谢您提供任何提示这里有什么问题。

解决方案

就我而言，解决方案非常简单。主要是 xorg.conf（来自 jjhughes57）让我走上了正轨。其余问题可以在 /etc/lightdm/lightdm.conf 中修复。我的最终版本是：

[LightDM]
seats=Seat:0 Seat:1

[SeatDefaults]
autologin-user-timeout=0
autologin-session=lightdm-autologin
greeter-session=lightdm-gtk-greeter


[Seat: 0]
xserver-layout=seat0
xserver-command=/usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -sharevts -novtswitch
autologin-guest=false
autologin-user=fx
autologin-user-timeout=0
autologin-session=lightdm-autologin
user-session=ubuntu

[Seat: 1]
xserver-layout=seat1

autologin-guest=true

一个问题是缺少“/usr/share/xgreeters/lightdm-gtk-greeter.desktop”。再次正确安装 lightdm-gtk-greeter 后，第二个 X 服务器成功启动。现在需要满足以下要求：

X 需要接受 :1 上的连接（假设 :1 是您的
fglrx-display) 您的用户需要在 :1 上打开 X 客户端的权限

实际上，我首先尝试使用 autologin-guest=false 不起作用。使用 autologin-guest=true 和正在运行的用户会话（作为来宾用户），您需要禁用 X 访问控制（至少这是最简单的）。例如：以 root 身份显示：0：

# su - guest-6ht0hq
guest-6ht0hq$ echo $DISPLAY
:0.0
guest-6ht0hq$ export DISPLAY=:1
guest-6ht0hq$ xhost +
access control disabled, clients can connect from any host
guest-6ht0hq$

现在在另一个终端上（以 root 身份）：

所以我真的很接近解决这个问题。我的基本想法是多座位会议。这允许 ATI 卡拥有自己的 X 会话，并且 Intel 显示器拥有自己的 X 会话。

确保 PCIE 是系统的默认显示，但您的板载 GPU 在系统 BIOS 中已启用
修改我们的 /etc/X11/xorg.conf 看起来像这样......
