［完美方案+无懈可击］ubuntu 14.04(LTS) + GTX 980Ti显卡配置

安装好系统之后出现的问题：

1 不能上网：后来通过删除链接新建一个以太网链接（自动DHCP）重启莫名其妙就好使了。

2 分辨率只有两个：1024x ? 和 800x600. 分辨率低到让人头痛。通过查看 系统设置--详细信息 发现：

当然这是后来安装显卡驱动之后的事儿了，之前图形那里显示的是cpu自带的渣渣集显。

当然安装好驱动后，分辨率自然就正常了。下面是安装的整个过程：

基本思路是：

１手动下载 NVIDIA-Linux-x86_64-375.66.run

２进入tty(一种非GUI图形界面的交互环境下，如果ctrl+alt+f1-6 ok的话，就不用向下面进入recovery-mode中)　在recovery-mode中如果密码啥的输入次数超过5次导致当前终端被锁定的话，记得ctrl+alt+f1-6　换一个其他终端接着霍霍．

３chmod 777  NVIDIA-Linux-x86_64-375.66.run

4 一路默认选择下来就ok

5 sudo reboot 选择正常启动流程就ok！

我一开始因为分辨率异常不能直接进入tty　(黑屏)　＆＆　使用ppa 安装总有依赖不满足问题．所以只能使用recovery-mode ，多亏了上面写blog的外国小哥，才得以在放弃之前，成功了．

I struggled a little for installing NVIDIA Drivers and getting Ubuntu 14.04 to bootup. I was stuck in black screen for a long time and system wasn’t booting up properly after i put in Graphics Card. Below are the steps i followed to fix the issue, may be will be of help for others too.

1. Go to Advanced Ubuntu Bootup options when system boots.
2. Select Ubuntu in Recovery Mode.
3. Launch root console in command prompt.
4. #3 will launch in read only mode. You need to mount it read/write. Enter following command “mount -0 remount,rw/”
5. If you have /home,/boot,/tmp or any other mount point on a separate partition, you can mount them with the command “mount –all”
6. Type “sudo nano /etc/modprobe.d/blacklist.conf”. This step is for opening editor to add some files to blacklist. Add below lines to this file.
   1. blacklist amd76x_edac
   2. blacklist vga16fb
   3. blacklist nouveau
   4. blacklist rivafb
   5. blacklist nvidiafb
   6. blacklist rivatv
7. sudo apt-get remove –purge nvidia*
8. cd ~/Downloads
9. Type dhclient eth0. Root mode generally doesnt have internet connection enabled, this command will enable wired internet connection (plugin ethernet internet cable)
10. wget http://us.download.nvidia.com/XFree86/Linux-x86_64/352.79/NVIDIA-Linux-x86_64-352.79.run
11. sudo chmod 777 NVIDIA-Linux-x86_64-352.79.run
12. sudo ./NVIDIA-Linux-x86_64-352.79.run.  This step will take some GUI based prompts, it is self intutive.
13. sudo nvidia-xconfig
14. sudo reboot
15. Select normal option for booting.
