Second attempt was much better
(do not know what was changed from last time - I've just rebuilt
driver).

Probably dependencies didn't get right, or something similar.

It shows screen with resolution of smaller panel (external LCD).
And duplicating LVDS to external VGA.

I've tried to change screens duplication to two-screens layout but
failed.
(probably I just do something wrong).

So this is the initial setup? Apparently RandR sets up for the lowest
common denominator... This is something outside of our control, except
for replacing the RandR algorithm, or RandR altogether.

In order to do two-screens layout, you have to specify that in the
monitor sections in xorg.conf (which are referenced by Option
"Monitor-CONNECTOR" "<monitor>", e.g. for Monitor-PANEL_LCD1/LVDS/TMDS)
by Option "LeftOf" "<other-monitor>". This is described in
xorg.conf(5).

Alternatively, you just increase the Virtual in the Screen section to
the combined output resolution, (which sets the maximum screen size
described above in the xrandr output), and set the second screen later
on e.g. with
xrandr --output PANEL_LCD1/LVDS/TMDS --right-of VGA_CRT1/DAC_A
