Comment 3 for bug 1864366

with KV 4.15.0-74 I got:

$ xrandr --listmonitors
Monitors: 1
 0: +*LVDS-1 1366/344x768/194+0+0 LVDS-1

efa@02cor2130:/etc/gdm3$ xrandr
Screen 0: minimum 320 x 200, current 1366 x 768, maximum 8192 x 8192
LVDS-1 connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 344mm x 194mm
   1366x768 59.97*+
...

with the other kernels, any try to set the same native resolution 1366 x 768 fail
