How can I make Linux automatically recognize the monitor's native resolution?

There is a relatively old laptop with a built-in Intel video card and an external monitor (D-SUB, classic 1280x1024, it has a D-SUB port and a DVI port in addition to D-SUB, but only D-SUB in the laptop). The monitor under Linux (XUbuntu 15.10) is recognized only at 1024x768 (under Windows it is detected correctly). To get 1280x1024 you have to run two commands each time:

sudo xrandr --newmode "1280x1024_60.00"  109.00  1280 1368 1496 1712  1024 1027 1034 1063 -hsync +vsync
sudo xrandr --addmode VGA1 1280x1024_60.00

Is there any way to make it self-determined normally?

You have open drivers for the video card. Install proprietary.

Once I wrote an article on habr to determine and automatically set the maximum resolution for the monitor when connected in a gentoo + i3wm environment via xrandr
