Therefore, I wrote a small program to test the VGA speed.Graphics Mode:

Are the names and proportions of various computer screen resolutions messy? Let's use the following articleArticleTo understand and summarize common screen proportions and resolutions. After learning about this, you will surely be able to make things better when designing images and webpages. In fact, there are only three common screen ratios: 4: 3, 16: 9 and 16: 10, plus a special 5: 4. 4:3 family Is the most common screen ratio, an ancient standard circulating in the TV era. Before

operation method is the same. The framebuffer region is mapped to the user State through MMAP, and then sent to other code in Xorg to process the ing address. V. Conclusion In qemu, The cirrus_linear_writeb function is called many times in the console. The reason why xserver is not called is as follows: First, under xserver, we map the framebuffer region (a region starting from 0x14000000) to the guest virtual address (by calling the/dev/fb0 MMAP function ), that is to say, all frambuffer opera

is a new function library that supports the Linux console and X Window, and the interface is relatively simple. To use MiniGUI correctly, you must install the libggi or svgalib revision. I suggest installing libggi because it provides support for the Linux console and X. In Linux, programs built on libggi can run on both the Linux console and X Window, thus improving program portability. In addition, for MiniGUI, if it can run on X Window, it can greatly facilitate program debugging. Another ad

Vga,dvi and HDMI are three video transmission standards, resulting in three interfaces based on three standards. So they are the standard name is also the interface name. It's often seen on our computers and TV devices. Even some graphics cards and monitors coexist on three interfaces.Everyone to three nouns is not unfamiliar, especially VGA is familiar, but for DVI and HDMI although heard but not necessari
