vaio touchscreen

reasons:In the Tslib source code in the/plugins/input-raw.c file check_fd function, there is a piece of code on the Development Board of the touch screen detection, if the following conditions as long as there is an unsatisfied, the report "Selected device is not a Touchscreen I Understand ", meaning the touch screen is not detected: if (!

This article describes several good things about debian for laptops-the Linux Release Technology-Debian information. The following is a detailed description. IBM's thinkpad series notebook is surprisingly good for linux support (I will only buy IBM's books later), and Debian has a software called tpctl, it is a toolkit for thinkpad series configuration and optimization. The installation is simple. apt-get install tpctl. However, to use it completely, you must manually compile the kernel. The

After Ubuntu is installed on a computer, it can run perfectly without any drivers, especially the latest version of Ubuntu. However, fingerprint recognition has always been a small pity. Hey, everyone knows that I am a GUI controller and I am mostly lazy. This article describes how to add a fingerprint reader to Ubuntu by using only the graphic interface. It mainly supports some models such as ThinkPad and Vaio. I. I would like to thank David jurenka

In Windows 8.1, the Simplified Chinese input experience has been significantly improved. Microsoft Pinyin added to the Sino-British mixed transmission, cloud input, new word hot word daily update, desktop and modern style application input experience consistent, touch-screen Keyboard Intelligent view switch, accuracy and input efficiency greatly increased. We also provide Wubi input method for Windows 8.1 users, so that users who prefer to use the Wubi input method have a better choice. This

Reprinted 1: Tslib ported to Android for touchscreen calibration. Since Android doesn' t provide a calibration tool,Tslib can be used to calibrate the touchscreen. the values obtained from ts_calibrate in pointercal file can be used in Android frameworks/services/Java/COM/Android/Server/inputdevice. java to have the correct screen coordinates. Ts_calibrate can be run from a serial console along with Androi

and some internal member variables are initialized.2.3 Data transfer processThe data obtained from the hardware device (touch screen) needs to be processed by input.c selection of the corresponding handler, and finally escalated to the user space. How to get the data from the hardware device (touch screen), it depends on the code in the XXX_TS.C, the source code in the XXX_TS.C is directly related to the hardware device. In XXX_TS.C we have to complete the register configuration associated with
