Use a tablet in a Linux operating system

Article Title: Use a tablet in a Linux operating system. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
The appearance of the handwriting Input System has narrowed the distance between everyone and the computer, so that we do not have to work hard on the input method. In addition, it is also a powerful tool for lovers of painting and graphic design. Using a tablet in Windows is a common practice, but what about using a tablet in Linux?
　　
Tablet and Linux version Selection
　　
　　 1. tablet Selection
　　
At present, Linux has improved its support for hardware, and has made great strides in supporting common hardware devices, such as graphics cards and sound cards. To drive smoothly, there is usually no major problem. However, the hardware and software components of the tablet are closely integrated with peripherals, not only the tablet and the necessary tablet driver, the Chinese Character handwriting recognition system with a high recognition rate must support the ability to freely input data (if it is only used for plotting, the limit will be much less ), in this way, it is difficult for Linux to support the ancillary functions of the tablet. Therefore, it is very important to choose a tablet product that supports a good Linux system.
　　
At present, there are a wide variety of tablet products on the market, such as mengting, Lenovo, and Hanwang. In addition, there are many product models and functions of the same brand, how can I choose a tablet that can be freely used in Linux? After my understanding, I learned that the tablet with better Linux support is a number of major brands, such as Hanwang, we recommend that you carefully check whether the system list supported in the product outer packing contains Linux. The author uses the "Han Wang Challenger", so the following content uses it as an example to illustrate that the use of other brands is similar to that of other brands.
　　
Tip: When you want to purchase a tablet in Linux, consider the interface issues in addition to the brand. Currently, there are two types of tablet: USB interface and serial interface, you are advised to choose a USB interface product when purchasing the product, because the latter is difficult to set in Linux.
　　
　　 2. Linux Operating System Selection
　　
Not all releases of Linux support tablet products due to intellectual property rights issues. However, the system must be equipped with a tablet product "Input Method" to support handwriting input (roughly equivalent to a tablet drive and a handwriting recognition system). There are not many released versions with built-in Chinese Character handwriting input methods, we recommend that you use the Red Flag desktop version 4.1, which is very convenient to use.
　　
Use a tablet in Hongqi desktop version 4.1
　　
After installing Hongqi desktop 4.1 (hereinafter referred to as Hongqi Linux), log on to the system and open the "Input Method" to see the "hand-written by Hanwang" option. However, the default installation method does not fully support the tablet. You also need to install the handwriting recognition software package in the tool disk of red-flag Linux.
　　
The installation method is also relatively simple. First, you need to put the attached tool CD into the optical drive or use the following command to load the CD image stored on the disk (SEE ):
　　 　
　　 Figure 1
　　
[Root @ localhost root] # mount-t iso 9660-o loop/root/Download/EnhancedDisc_dt41.iso/mnt/cdrom.
　　
KDE runs the CD automatically like Windows. You only need to wait for a moment before the dialog box for installing the additional tool is displayed. After all the options are selected, click "Next" to display the "select Software Package" dialog box. After all the options are selected, you can easily install the additional tools in a short time, so that all the support for the pen is in place.
　　
Then insert the data cable of the tablet into the USB interface of the computer and restart the system. After logging on to the system, run the OpenOffice Writer or Notepad program, locate the cursor, and click the "Input Method" icon, then, select "hand-written by the Chinese King" to enter Chinese characters and symbols by hand on the tablet (see figure ).

Tip: MB disk space is required for fully installing the red-flag Linux append tool. If it is unclear whether the disk space supports the installation of the append tool, you can use "df-m" on the command line to view the remaining disk space.
　　
In addition to handwriting input and drawing, the tablet is similar to the mouse function and can be used for Common Desktop operations. For example, you can place the pen above the valid area of the pen, move the cursor with a pen, and then click the tablet twice to open the file or run the program. This is very convenient for anyone familiar with tablet operations. Note that you do not need to switch to the hand Input Method of the Chinese king when using the tablet with the mouse.
　　
With the rapid development of Linux, it is time to easily and conveniently use the tablet in Linux. Just pick up your tablet!
