小白求助，ubuntu14.04 更新了显卡驱动就这样了
我有更好的答案
你好。如果更新显卡 驱动后出了问题，可进入设备管理器，把显卡驱动回退到原来的驱动程序。

Ubuntu 14 安装NVIDIA显卡驱动（附加驱动）
Ubuntu 14 自带和使用了一个“开源显卡驱动”，我的电脑ThinkPad E440是双显卡（NVIDIA独立显卡 和 集成显卡），如果不使用NVIDIA的专业驱动，是发挥不出独立显卡的好效果的。
好在，Ubuntu 14中，切换显卡驱动还是非常方便的，

Ubuntu7.10 终于解决装好nVidia显卡驱动黑屏的问题了
DearMichael发布于
&&字号: &&&&(网友评论&0&条)&
昨天在受限驱动里装好7600GS以后进登录界面就黑屏，我的benq PF71G+显示器显示“Out of range”，盲打进用户名密码可以听到启动声音，看样子就是刷新率的问题，暂时在LiveCD中把备份的xorg.conf恢复回去，启动正常了。
今天继续解决这个问题，详细研究了xconfig以后生成的xorg.conf文件， 把HorizSync和VertRefresh数值调低 ，把monitor和Device的ModelName手动填上，我的是BenQ FP71G+和nVidia Corporation G70 [GeForce 7600 GS]，Google一下找到一个Screen的配置文件，先不管了全部copy过来，重启，OK了。
附xorg.conf文件完整配置，如果有人跟我同样的状况可以完全copy后把ModelName改成自己的应该就可以了。QUOTE:# nvidia-xconfig: X configuration file generated by nvidia-xconfig

标签：现在deep learning这么火，早就想学习学习，最近实验室买了块Titan X显卡，但是目前木有购买相应的服务器，一盘的台式机上带不动这块显卡，而且实验室配置的台式机相当陈旧，配置早已跟不上时代，装上也跑不动。
但是实验室有太工控机，配置还算可以，i7-3770T处理器，所以寻思着把显卡装这台机子上，当然，自带的电源适配器也是带不动的，所以特意买了个1000w的电源，插上显卡总算可以带动。
OK，装上Ubuntu14.04，然后参考网上某个教程安装Nvidia官网下载的驱动，跑个网上的demo，用GPU可以跑。。。。
但是。。。悲剧的是这台工控机不知道是怎么回事，只要断电再重启的时候，就会出现无法进入系统（出现启动选择界面，点击进入后崩溃重启，反复），开始以为是bios设置问题，就改了一些设置，发现真的有用（虽然后来证明是错觉），真的进去了，直接从Ubuntu点击重启，启动也没有任何问题，但是关掉电源第二天开机又是不断重启，改改bios后偶尔能够顺利进去系统，但是修改bios成功登录呈现随机现象，并不是设置成某种状态就可以，而是改一改偶尔能够登录。。。
而且当出现一直崩溃重启状态时就算想重装也是在出现安装界面后重启
今天某一个靠运气登录成功，想着是不是显卡驱动安装有点问题，于是准备重装一遍，按照这个教程又装了一遍：
from:&http://askubuntu.com/questions/451221/ubuntu-14-04-install-nvidia-driver
You can download the driver for your video card for Ubuntu 64bit&. Assuming that you are using Ubuntu 64bit now. If you installed Ubuntu 32 bit, there is 331 version of the same driver for Ubuntu 32bit. Save your driver somewhere where you can easily access it, like your user home directory or inside a newly created&nvidia&directory in your user home directory.
To be able to install your nvidia driver you have to remove your previous video driver with this code in a terminal window:
sudo apt-get remove nvidia* && sudo apt-get autoremove
这里我还加了一步：&sudo apt-get --purge remove xserver-xorg-video-nouveau-lts-utopic
(参考https://help.ubuntu.com/community/BinaryDriverHowto/Nvidia，但是文中是卸载xserver-xorg-video-nouveau，我的机子上只有上面那个包)&
After you finish with this one, you should also blacklist the nouveau driver by editing this file with either:
gksudo gedit /etc/modprobe.d/blacklist-nouveau.conf
sudo nano /etc/modprobe.d/blacklist-nouveau.conf
&and add these lines at the end:
blacklist nouveau
blacklist lbm-nouveau
options nouveau modeset=0
alias nouveau off
alias lbm-nouveau off
If, by any chance, there is no&blacklist-nouveau.conf&present in /etc/modprobe.d/, you can save your file as&blacklist-nouveau.conf&when prompted.
And you can also disable the Kernel Nouveau by typing these lines in a terminal window:
echo options nouveau modeset=0 | sudo tee -a /etc/modprobe.d/nouveau-kms.conf
and after that
update-initramfs -u
Now you can reboot your computer, and when you get to the login prompt, press Ctrl+Alt+F1 to exit to the terminal console. Login with your username and password.
Go to the directory where you saved your nvidia driver using the command&cd&in the terminal console. Eg.&cd nvidia&considering that you are already in your user home directory after you login. You can use command&dir&to be able to see your exact driver‘s name.
To stop your display manager or the X server, you can type in the console this code:
sudo stop lightdm
sudo lightdm stop
If you are not using&lightdm&as your default display manager (DM), replace lightdm with your default display manager, which can be either&kdm&or&gdm&or whatever your display manager is.
You should get a message in the terminal console saying --& lightdm stopped/waiting
And now you can finally install the nvidia driver using a code similar to this one:
sudo sh NVIDIA-Linux-x86_64.....run
(for Ubuntu 64bit)
sudo sh NVIDIA-Linux-x86.....run
(for Ubuntu 32bit)
If you don‘t type the exact name of the driver, you‘ll get this message:&NVIDIA-Linux... could not be found&and you should type again the code for installing the driver.
Nvidia installer automatically installs the driver, and at the end it will ask you whether you want to save your new X configuration. Press Yes. After reboot and getting to your desktop and changing your NVIDIA settings as you please you should open a terminal window and type in this code:
sudo nvidia-xconfig
to save your new nvidia configuration in /etc/X11/xorg.conf.
You might need to install some extra software packages if nvidia installer gives an error and prompts for missing dependencies:
sudo apt-get install dkms fakeroot build-essential linux-headers-generic
But you need to install all these missing packages only if nvidia-installer can‘t do the job by itself.
It can happen that after reboot your system shows a black screen or enters the low graphics mode. To fix this you should exit again to the console terminal, login with your username and password, and use the code provided above&sudo nvidia-xconfig&and also make use of the following tutorial. It is meant to&&assuming that they haven‘t fixed this bug in Ubuntu 14.04.
结果貌似真的有用，到目前为止，断电重启都顺利登录。
所以记录下这个显卡安装教程。
其中一个问题是中间一个重启步骤的时候好像出现的根目录/损坏的提示，但是按提示修复后一切正常
