NVIDIA Optimus 介绍:http://baike.baidu.com/view/4266252.htm
好了问题来了,装Xorg 还有官方驱动 都成问题了。
目前解决方案 进入Bios禁用一块显卡。
集显能禁掉吗,可是笔记本的BIOS里好像根本没有那个选项,
在WIN7下禁掉集显直接黑屏,U下是什么情况?
使用这种技术机器有 GT420M, GT425M, GT435M, GT445M,GT550M
我用 华硕N53 为例说下 如何解决
原文http://www.martin-juhl.dk/2011/05/optimus-on-linux-problem-solved/
首先去 我的资源站下载东西
http://down.51cto.com/data/225275
下载下来以后解压到你的个人目录比如我的就是/home/luozhuang
下面都用/home/luozhuang/bumblebee 目录为例:
cd /home/luozhuang/bumblebee
sudo ./install.sh
运行到
UBUNTU-based distribution found.
Welcome to the bumblebee installation v.1.6.40
Licensed under Red Bull, BEER-WARE License and GPL
This will enable you to utilize both your Intel and nVidia card
Please note that this script will probably only work with Ubuntu, Debian, OpenSuSE and Fedora Based machines
and has (by me) only been tested on Ubuntu Natty 11.04 and Fedora 14 but should work on others as well
Are you sure you want to proceed?? (Y/N)
这输入Y
接下来会去下载最新的驱动
Installing needed packages.
一句话OTL,慢到掉渣。。。
请Ctrl+c 终止执行
打开上面那个资源,安装自己系统的驱动包
lucid(10.04)
maverick(10.10)
natty(11.04)
uname -a
显示
Linux luozhuang-N53SN 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:24 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux
看见x86_64说明这是 64位版本
我是11.04 根据上面输出应该安装nvidia-current_275.19-0ubuntu1~natty~xup1_amd64.deb
双击就可以用Ubuntu 软件中心打开然后安装。
安装好了以后重新执行
cd /home/luozhuang/bumblebee
sudo ./install.sh
到这里:
Select your Laptop:
1)Asus N53SL Sven Bettscheider Ubuntu 11.04
2)...........
...........
这里很重要,让你选择 你的机器还有操作系统,这个软件问题就在这里
只能支持有限的本本,不过好处就是笔记本都是大规模制造的,显卡就那么几个
像比如我的机器 只要大体符合就可以了,不过操作系统要弄对。
我的是N53SN 不管什么SN还是SL都一样,我就选择1就可以
The Image Transport is how the images are transferred from the
nVidia card to the Intel card, people has different experiences of
performance, but just select the default if you are in doubt.
I recently found out that yuv and jpeg both has some lagging
this is only noticable in fast moving games, such as 1st person
shooters and for me, its only good enough with xv, even though
xv sets down performance a little bit.
1) YUV
2) JPEG
3) PROXY
4) XV (default)
5) RGB
大体意思是输出方式,我觉得默认也就是4 就足够了,1或者2 画面好,但是看电影或者FPS 会有延迟
最后出现
After that you should be able to start applications with"optirun32 <application>" or "optirun64 <application>"
optirun32 can be used for legacy 32-bit applications and Wine Games.. Everything else should work on optirun64
意思就是 optirun32 + 应用程序 或者optirun64 + 应用程序
最后我说下心得吧:
建议安装新版Ubuntu,我已经试过 10.04 ,因为没有Intel显卡驱动,估计你也会很麻烦。
bumblebee 只能解决关显卡问题,跑VMware 还是不能3D加速。
如果你的机器没法 bumblebee 那就装Ubuntu 11.04 吧,无非就是机器热一点还是能用。
问题:
11.04 +intel 卡跑unity还是不稳定,我换了Fedora 15+ Gnome 3 也是经常死机。。。
总之还是大问题。。。
