How can i save the file in my system.

No idea, since you don't say what file you're trying to save, tell us anything about the version/distro of Linux you're using, your hardware, or what changed to cause this problem. Provide actual details and we can try to help.

This suggests that the monitor is only advertising a maximum resolution of 1024x768.

One way to get the 1920x1280 support is to create customisation in /etc/X11/xorg.conf.d, but advice for this requires more detail.

Another alternative might be to append a kernel boot option like ' video=VGA-1:1920x1080@60e'. The VGA-1 is from my system, so you would need the graphic output name on your system that can be seen in the output of 'ls /sys/class/drm'.

So this is a NEW installation...how do you know it was 1920*1080 before, then?? And again, you aren't telling us anything about your monitor or video card, nor the version of Deepin, nor have you answered what file you're trying to save, how. What desktop GUI are you using? Have you tried going through the control center and adjusting it?

There are several reasons why this might happen. We need more information in order to determine the cause and solution. Please run the following commands from an X terminal and paste the results here to give us this information:

Code:

cat /var/log/Xorg.0.log | pastebinit
sudo inxi -U 2>/dev/null
sudo inxi -SGIayz

Please wrap output from the last command in code tags.
