One thing about Linux system resolution

Linux system resolution-Linux general technology-Linux technology and application information. For more information, see the following section. One morning, I went to the company to open my computer and found that the resolution was incorrect. It is clearly 1920x1200. How can it be changed to 640x400, and it cannot be changed. Restart and switch to windows. The resolution is correct. It seems that it was a problem with linux, and it was switched back again, and the/etc/X11/xorg. conf was read in the form, and no problem was found. If you try to access the Internet and use someone else's xorg. conf, you may be confused. I also tried the two graphics cards separately, but it's still not a problem. My head is obviously bigger than the font that is full screen.

Reinstall it! Because the system is fedora core 6 and has been in use for more than a year, and some strange problems have occurred recently, I decided to install Ubuntu8.04. The installation system is fast. However, after the installation, the resolution is still incorrect. It is still not possible to install the graphics card driver. What is the problem.

Then, something sad to me happened. I suddenly found that the connector connecting the VGA port of the monitor was loose. I pulled it out and re-inserted it. Restart X and the resolution will be normal. This reminds me that the same thing happened on the day I first moved to this office a year ago. It was just a little tight at that time.

Why is the connector loose overnight. Due to a problem with the connector screw, it cannot be fixed on the display. Normally, it can only be inserted on the monitor. Although it cannot be fixed, the line will not be loose as long as it is not forced. The reason for the loose overnight is that the cleaning aunt kindly helped me clean the table. As a result, the Force was too high and the line was loose. This is well-founded, because before I leave the company, I usually tidy up the table and place the keyboard and mouse. But the next day, we can see that these two locations are exaggerated, as if they had just fought for a site on the table. When I arrived at the company that morning, the keyboard was pushed a lot down the display. we can imagine that the line was broken due to this process.

Reload the system. It's really hard to use Ubuntu8.04.

In addition, this reminds me of the questions of test engineers interviewed by a company in the past. Q: When you go home one day and start a TV, you find that the TV set that you can press it to open cannot be opened today. What do you think is the reason? Many people have said many reasons for professional and complex reasons. At last, I was asked: Why didn't you check whether the power cord was connected first? (Author: To The Future)
