为什么双显卡查询有的人显示VGA+3D Control 有的人却显示两个VGA的提示呢

我的显示是这样，

可是更多的我看到的是这样的
A、00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
B、01:00.0 VGA compatible controller: NVIDIA Corporation GK104M [GeForce GTX 670MX] (rev ff)"


请问这两者有什么区别吗

我不知道怎么调的，gtx960m可以显示了。非常感谢。刚才不能输入汉字不知道怎么回事，比如输入。han，就会自动分割成ha‘n

意思是说 被定义成3d-controller的卡是不可以不独立进行图形渲染 的吗？ 我在贴吧还看到一个观点说 --- “因为有的双显卡的独立显卡是接在集成显卡上输出的，所以失败无数次，因为驱动总是只开一个显卡“ 我感觉我现在好像也是这种情况，安装完nvidia-352的显卡驱动以后，用prime切到intel集成显卡，重启一切正常，然后再切到nvidia显卡的时候重启黑屏，然后 我卸载nvidia驱动，开机正常 ，现在机子上装了nvidia-352 ，但只用intel集显，

还有切换到nvidia驱动的时候 系统设置打不开，显示系统内部发生错误，

问题表达的有点混乱，因为折腾了3天我也快不知道到底是哪里出的问题了，下面贴一些信息看下您帮我看看这是是什么原因装完驱动切到独显重启就黑屏，
网上的资料找了一遍但都是卸载驱动正常进去界面就没下文了

下面是切成intel集显的一些信息，

最新情况，我把neavou加入黑名单，然后选择nvidia驱动，注销，然后显示 your system run in low graphics

百度一下 这个问题貌似参考的资料多点

[poloshiao]

以下是切成nvidia显卡时的信息：
lspci -v
Kernel driver in use: i915
sudo lshw -c video
configuration: driver=i915 latency=0

1. i915 是 Intel 的開源驅動
不是 nvidia 的閉源驅動

显示 your system run in low graphics

2. 表示沒有合適驅動 或 未正確設定/啟用

学习了，请问怎么查看是否正确设定启用了呢？需要自己手动设定的吗？驱动的配置文件，日志什么的在哪里我都还没搞清楚

gtx960M

3. http://www.geforce.com/hardware/noteboo ... e-gtx-960m
gtx960M 具有 optimus 功能
3-1. http://www.geforce.com/hardware/technology/optimus
3-2. http://www.geforce.com/hardware/technol ... technology
Using NVIDIA's Optimus technology, when the discrete GPU is handling all the rendering duties, the final image output to the display is still handled by the Intel integrated graphics processor (IGP).
3-2-1. 具有 optimus 功能的雙顯卡
設計上就是 nVidia 負責處理 3D 及 高端 計算
把 單純顯示的任務 交給 Intel
兩者合作 效能較高 溫度較低

双显卡查询有的人显示VGA+3D Control

3-2-2. 上面 3-2-1. 的描述 希望有助於你對 3D Control 的理解

切成intel集显
切成nvidia显卡

3-3. 為何你要另外追求切成單顯卡
捨棄原來設計的兩張顯卡合作模式 ?

现在机子上装了nvidia-352
怎么查看是否正确设定启用了呢

4. 表示你是從 Ubuntu 套件庫 安裝閉源驅動 nvidia-352
4-1. 細節參閱
https://help.ubuntu.com/community/Binar ... wto/Nvidia
NVIDIA drivers provided by the Ubuntu repositories

5. 一切搞定 重新開機

好的，谢谢你的回答，我还有点不懂那里面的驱动和软件中心里面的有什么区别？还有发现不管是这里还是软件中心的驱动版本都写着适用ubuntu14.04.1 会不会和我现在的14.04.4的系统不兼容呢？

[poloshiao]

那里面的驱动和软件中心里面的有什么区别？

都一樣

[Lee2016]

那里面的驱动和软件中心里面的有什么区别？

在你的那个链接帖子里找到了一个和我的情况和相似：

我的也是重启以后听到系统开机提示的声音，但是屏幕一片黑，照他的方法还是不行

第二次把ignore的那一行去掉了还是不行
