14.10升级到15.04 Nvidia显卡问题

[OpenL]

两台笔记本acer e1-471g 和 hp 242g1 都是Hd4000和nvidia primus双显卡
14.10升级到15.04后，驱动是ubuntu安装的私有驱动nvidia340.76，nvidia-settings是开启nvidia显卡的，发现比以前14.10是稳定了，不会时不时画面卡住。
现第三台笔记本hp 242g1，14.10升级到15.04后，驱动是ubuntu安装的私有驱动nvidia340.76，但因为升级前nvidia-settings是只开启intel显卡的，于是升级后在nvidia-settings中点击开启nvidia显卡，然后重启，问题来了，启动进入图形登陆界面便反复出现图形登陆界面，没办法正常登入。闪出一个英文提示大意是低级显卡，要自行重新设置。
尝试了一些以前的解决方法都不行，重启到grub看到ubuntu 15.04多了upstart模式……
现在移除所有的nvidia相关文件：apt-get --purge remove nvidia-*
重启后可以登陆了，重装nvidia驱动还是不行，请教各位大虾如何解决？

poloshiao, 谢谢，搞定了。
用系统设置——软件和更新——附加驱动，装了几遍都没成功，
最好打开用终端输入命令安装好了，不明所以.

poloshiao, 顺带问下，nvidia图形性能怎么调节？两台同样是 hp 242g1型号的笔记本　配置一样　nvidia-settings 里面的设置完全一样　但是同样情况下运行glxgears 一台有７５００左右的ＦＰＳ　另一台就有近１１０００ＦＰＳ　相差也太远了。

[poloshiao]

nvidia图形性能怎么调节？

1. nvidia-xconfig
gksudo nvidia-xconfig
或
nvidia-xconfig
1-1. http://manpages.ubuntu.com/manpages/luc ... fig.1.html
nvidia-xconfig - manipulate X configuration files for the NVIDIA driver
1-2. http://us.download.nvidia.com/XFree86/L ... onfig.html
Chapter 6. Configuring X for the NVIDIA Driver

2. nvidia-settings
gksudo nvidia-settings
或
nvidia-settings
2-1. http://manpages.ubuntu.com/manpages/pre ... ngs.1.html
nvidia-settings - configure the NVIDIA graphics driver
2-2. http://us.download.nvidia.com/XFree86/L ... tings.html
Chapter 24. Using the nvidia-settings Utility

3. 第一次 使用 gksudo 請先安裝 gksu 套件

运行 glxgears 一台有 ７５００左右的ＦＰＳ　另一台就有近 １１０００ＦＰＳ

4. Glxgears 的 FPS 僅供參考
4-1. http://wiki.cchtml.com/index.php/Glxgea ... _Benchmark
Glxgears_is_not_a_Benchmark
glxgears is an OpenGL program that reports FPS (frames per second) numbers. However, it is a very limited 'test'.

glxgears FPS scores, just for fun

poloshiao哥，我看你这个帖子了，这个貌似是解决在线视频（flash）问题的，这个问题，我这边换浏览器已经处理了，我现在的问题是，用mpv或vlc放avi视频一黑一闪，还没处理。
