In May January, I installed Windows 7 Beta on my laptop (integrated with Intel 965 graphics card), but I found a very serious problem. In some real interfaces, A video card driver error occurs. Once an error occurs, aero will become invalid, but Windows 7 will immediately be able to recover the driver. This problem has actually been encountered in Vista, but with the official HP driver installed, there is no problem. Unfortunately, the official driver
LSC the Intel HD Graphics 520 math test (mathematical Operations test) project will have an error, as shown in the following figure:
Impact of the product: ThinkPad
Impact of the series: E460, E560
Configuration of impact: Intel HD Graphics 520
Solution:
Please upgrade the Intel graphics driver higher than version 10.18.15.4279
1, press the "Windows logo key +r" key combination, bring up the "Run" dialog box, type "Devmgmt.msc", and then click "OK" to bring up "Device Manager";
2. Under "Display adapter", you can see that there are two devices, the front of which has no exclamation mark, and no question marks, it means that two video card driver has been successfully installed. The following figure shows the "Intel +nvidia Graphics" configuration;
3, the following imag

1, this time we draw a smaller figure, convenient for us to explain the bulk copy method.
2, after a good copy of a rectangle, is not every time to hold down the "alt" key, and then move with the mouse, a copy? That's too much trouble. After we copy the first one, you can press the CTRL key and the "D" key to quickly copy the second
3, repeatedly hold down the "CTRL" Key Plus "D" key, you can quickly copy many, forming a row of small rectangles
4, and then use the "selection Tool", all
1 Low-level coloring language TgsiThe OpenGL program uses the GLSL language to program the programmable graphics processor, the GLSL language (the following high-level coloring language refers to GLSL) is a high-level language of syntax similar to C, in the GLSL specification, GLSL language is first translated into the teaching of low-level class assembly language, and then translated into a hardware-specific instruction set.

Recently study Ros operating system, need to use Ubuntu as the basis, so installed a, used to do the development has been used in CentOS, with Ubuntu some not used to. Because the Ros simulator needs to use the 3D simulation, so installed ubuntu12.04 after a look at the video card to identify the No, the results are very sad to find that the graphics drive is unknown. It seems that Ubuntu support for my dual graph

1, we first find the "computer" on the desktop and then right-click it pop-up menu Device Manager-Display adapter Click "Update Driver Software";
2, then our computer will automatically scan all updatable or problematic drivers, such as will display "automatic search updated driver software";
Okay, if you have a problem, it will be automatically updated, if you update the graphics driver in this way or no problem,
