most kernel start with 640x400 resolution

[efa]

I'm not sure what is the target package for this trouble, anyway I have a notebook with an Nvidia G102M, and till kernel 4.15.0-74 the video driver work well at native screen resolution of 1368x768 @ 60.00 Hz, while all the subsequent kernel start in 640x400 from the display manager/login screen, and seems do not support any other resolution. I'm not sure if the CLI part of kernel and init are at low lines/column too.

I have the following kernel installed:
4.15.0-74
4.15.0-88
5.0.0-37
5.3.0-24
5.3.0-28
5.3.0-40
only 4.15.0-74 work as expected.

For each kernel KV I have the following packages:
linux-headers-KV
linux-headers-KV-generic
linux-image-KV-generic
linux-modules-KV-generic
linux-modules-extra-KV-generic

More I have the following packages installed:
xserver-xorg-video-all-hwe-18.04
xserver-xorg-video-nouveau-hwe-18.04

and neither of the following installed:
linux-modules-nvidia-390-generic
linux-modules-nvidia-390-generic-hwe-18.04
linux-modules-nvidia-430-generic-hwe-18.04
linux-modules-nvidia-435-generic-hwe-18.04
linux-modules-nvidia-390-KV-generic
linux-modules-nvidia-430-KV-generic
linux-modules-nvidia-435-KV-generic

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

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
