Tips for changing the resolution of a Linux operating system

Article Title: Tips for modifying resolutions in Linux operating systems. 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.

Open a terminal window in the desktop environment, run the xvidtune command, and drag VTotal in the middle key. Then, the Vertical sync value changes, tune it To the value you want (not too high), and press test to try the effect. If there is no problem, press show to write down the output line shown in the terminal window. Statements like this:

"1024x768" 94.50 1024 1093 1168 1376 768 769 772 + hsync + vsync

Edit the/etc/XF86Config file (most of the current systems are/etc/X11/XF86Config or/etc/X11/XF86Config-4), find Section "Monitor", you should see something similar

Modeline "1024x768" 94.50 1024 1093 1168 1376 768 769 772 + hsync + vsync

Such a statement (if not, add Modeline to the beginning of the log and add it to the front of the EndSection, and Linux will not ), modify the numeric values according to the recorded items, save the changes, and restart xwindow.

Sometimes you find that the screen is biased to one side after Windows is enabled (my machine is very biased, probably 3 cm to the right ), if the adjustment function of the monitor is adjusted, the switch is biased under win. The solution is to first downgrade the positive position of win, start linux, and run xvidtune, use the left and right buttons to adjust the screen position, show it, and write it down. Then, modify the file as shown above and the file will be OK.
