ubuntu nvidia 驱动安装

显卡是nvidia geforce 8400M G, ubuntu 论坛上说的方法是装nvidia-glx, 我看了看源里， 除了这个包还有个nvidia-glx-new, 但是看说明，似乎太老了， 不认geforce8。 事实确实如此。

于是上nvidia官网下了个驱动， 叫做NVIDIA-Linux-x86-100.14.11-pkg1.run,但是装了不能用, X的错误信息说nvidia kernel interface版本不匹配， 而这个应该是ubuntu的linux-restricted-modules包提供的， 问题可能在这里.

后来在nvidia论坛上证实了这一点， 在http://www.nvnews.net/vbulletin/showthread.php?s=5e6ef2b1d1fb97772f6b738b135f220b&t=72490说道

If you wish to install the NVIDIA Linux graphics driver on a Debian GNU/Linux or Ubuntu system that ships with Xorg 7.x, please ensure that your system meets the following requirements:

* development tools like make and gcc are installed
* the linux-headers package matching the installed Linux kernel is installed
* the pkg-config and xserver-xorg-dev packages are installed
* the nvidia-glx package has been uninstalled with the --purge option and the files /etc/init.d/nvidia-glx and /etc/init.d/nvidia-kernel do not exist

If you use Ubuntu, please also ensure that the linux-restricted-modules or linux-restricted-modules-common packages have been uninstalled. Alternatively, you can edit the /etc/default/linux-restricted-modules or /etc/default/linux-restricted-modules-common configuration file and disable the NVIDIA linux-restricted kernel modules (nvidia, nvidia_legacy) via:

DISABLED_MODULES="nv nvidia_new"

Additionally, delete the following file if it exists:

/lib/linux-restricted-modules/.nvidia_new_installed

Please note: unfortunately, it has become difficult to keep track of the pre-/post-installation steps required for [K]Ubuntu, and the above instructions may be incomplete. If in doubt, it is recommended that you use your distributor's NVIDIA Linux graphics driver packages, exclusively.

其实我更愿意用配置文件的方法禁掉nvidia-glx, 但是后来想了想， 还是把这个包删了。

这时再装一遍， 重启gdm, 哈哈， 出现了nvidia的logo, 成功了。 如果不想要logo, 在xorg.conf适当位置加入Option "NoLogo" "1"就行了

另外xserver-xorg-dev似乎不是必需的， 至少我这里没装这个也能成功安装驱动。

Determine Perspective Lines With Off-page Vanishing Point

In perspective drawing, a vanishing point represents a group of parallel lines, in other words, a direction. For any point on the paper, if we want a line towards the same direction (in the 3d space), we simply draw a line through it and the vanishing point. But sometimes the vanishing point is too far away, such that it is outside the paper/canvas. In this example, we have a point P and two perspective lines L1 and L2. The vanishing point VP is naturally the intersection of L1 and L2. The task is to draw a line through P and VP, without having VP on the paper. I am aware of a few traditional solutions: 1. Use extra pieces of paper such that we can extend L1 and L2 until we see VP. 2. Draw everything in a smaller scale, such that we can see both P and VP on the paper. Draw the line and scale everything back. 3. Draw a perspective grid using the Brewer Method. #1 and #2 might be quite practical. #3 may not guarantee a solution, unless we can measure distances/p...

[转] UTF-8 and Unicode FAQ for Unix/Linux

这几天,这个东西把我搞得很头疼 而且这篇文章好像太大了,blogger自己的发布系统不能发 只好用mail了 //原文 http://www.cl.cam.ac.uk/~mgk25/unicode.html UTF-8 and Unicode FAQ for Unix/Linux by Markus Kuhn This text is a very comprehensive one-stop information resource on how you can use Unicode/UTF-8 on POSIX systems (Linux, Unix). You will find here both introductory information for every user, as well as detailed references for the experienced developer. Unicode has started to replace ASCII, ISO 8859 and EUC at all levels. It enables users to handle not only practically any script and language used on this planet, it also supports a comprehensive set of mathematical and technical symbols to simplify scientific information exchange. With the UTF-8 encoding, Unicode can be used in a convenient and backwards compatible way in environments that were designed entirely around ASCII, like Unix. UTF-8 is the way in which Unicode is used under Unix, Linux, and similar systems. It is now time to make sure that you are well familiar ...

Moving Items Along Bezier Curves with CSS Animation (Part 2: Time Warp)

This is a follow-up of my earlier article.  I realized that there is another way of achieving the same effect. This article has lots of nice examples and explanations, the basic idea is to make very simple @keyframe rules, usually just a linear movement, then use timing function to distort the time, such that the motion path becomes the desired curve. I'd like to call it the "time warp" hack. Demo See the Pen Interactive cubic Bezier curve + CSS animation by Lu Wang ( @coolwanglu ) on CodePen . How does it work? Recall that a cubic Bezier curve is defined by this formula : \[B(t) = (1-t)^3P_0+3(1-t)^2tP_1+3(1-t)t^2P_2+t^3P_3,\ 0 \le t \le 1.\] In the 2D case, \(B(t)\) has two coordinates, \(x(t)\) and \(y(t)\). Define \(x_i\) to the be x coordinate of \(P_i\), then we have: \[x(t) = (1-t)^3x_0+3(1-t)^2tx_1+3(1-t)t^2x_2+t^3x_3,\ 0 \le t \le 1.\] So, for our animated element, we want to make sure that the x coordiante (i.e. the "left" CSS property) is \(...
