Modify resolution in ubuntu

In Ubuntu, I thought the resolution was changed because the video card driver was not properly installed. However, I tried several times according to the tutorial. The maximum desktop resolution of 1024*768 was only 65 HZ, and it was quite eye-catching. Step 1: Enable/etc/X11/xorg. conf to modify the resolution in ubuntu, but back up a copy before enabling it!

Modify resolution in Ubuntu

I thought it was because the video card driver was not properly installed, but I tried it several times according to the tutorial. The maximum desktop resolution of 1024*768 was only 65 HZ, and it was quite eye-catching.

To modify the resolution in ubuntu, follow these steps:

Step 1: Open/etc/X11/xorg. conf, but remember to back up one copy before opening it! Use sudo cp/etc/X11/xorg. conf/etc/X11/xorg. conf_backup to generate a backup named xorg. conf_backup.

Step 2: search for "Section" and press Ctrl + F. In fact, there is not much difference with Windows. Find the "Section" Monitor "code segment. As follows:

Section "Monitor"

Identifier "Generic Monitor"

Option "DPMS"

HorizSync 30-82 (modify the position of the screen resolution)

VertRefresh 50-75 (you can change the screen resolution to the maximum value supported by the video card, for example, set it to 50-85)

Location where modline is placed

End Section

Step 3: Enter the terminal, enter the command gtf 1024 768 85, output a modeline, and add this sentence to the Section "Monitor" code segment.
