I am trying to define a new currently unsupported resolution on a virtual machine (Linux Deepin client) with a 1366×768 screen. So I first try to use command cvt:
cvt 1366 768 60
and it returns:
# 1368x768 59.88 Hz (CVT) hsync: 47.79 kHz; pclk: 85.25 MHz
Modeline "1368x768_60.00" 85.25 1368 1440 1576 1784 768 771 781 798 -hsync +vsync
which is incorrect as it changed the 1366 to 1368! Why is this happening? I need this output to use it with X. So I am stuck!

The generated modeline is correct, CVT requires that horizontal counts are a multiple of 8:
All definitions referring to the horizontal timing, including the horizontal active pixels, horizontal total pixels, sync pulse duration and “Front porch” and “Back Porch” times, must be divisible by
eight, and preferably by higher powers of two.
1366 isn’t divisible by 8, so cvt rounds up to the next integer which is, 1368. The generated modeline should work fine with your screen.
