Therefore, we can use the frame buffer in the vesa mode of kernel, and then use the xfree86 linux frame buffer driver. In this way, the screen is invisible, and there

with the situation of the kernel because it is only used by one machine. On the other hand, in order to reduce unnecessary complexity, we decided not to use the support of the kernel module, but to compile all the required things directly into the kernel. In this way, all necessary functions are added to the compiled Kernel on a common 586 motherboard, generally less than 800 KB. Therefore, this method is feasible. It also reduces the complexity of init scripts. In terms of running, because the

kernel code is to be loaded into the memory, it will not cause a waste of memory.
On our target platform, we want to use USB storage devices. Another thing to note is the support for Frame buffer. This is mainly to support XFree86. In general, if our video card is directly supported by XFree86, it is of course the best, so we do not need the Kernel support of frame buffer. However, if XFree86 does not support our video card, we can consider using the VES
My Ubuntu is also an intel integrated driver. I didn't plan to get the driver (vesa can be used to display it). I just wanted to play a movie with some cards, and even the most basic tuxracer was not enough, so I had a bad google attack and finally got it done. At least tuxracer didn't card and proved that the settings work. voila: The following steps are for reference only: 1. Install the graphics card driver xorg-video-intel, is intel's graphics car
to the Monitor section of the XFree86 configuration file. This section contains information such as the monitor's horizontal scan frequency range, vertical scan frequency range, and display mode supported by the monitor. Similarly, the automatic detection of the monitor means that the above information of the monitor is automatically read through the program. The correct settings play an important role in the normal display of XFree86.
For display information detection, it must support vbe (

Other files are for specific graphics card chips.
