[Question] vesa driver with RandR 1.2

[Kan-I Jyo]

Dear list,

I am currently using xserver-xorg-video-vesa 1.3.0 along with
xrandr 1.2 on one of my laptop.

It is to my curiosity that is there any support on RandR in vesa
driver since it seems to fail detecting an external monitor.

I have taken a look on the git tree of vesa driver and it seems
that support for RandR 1.2 is on the TODO list.

<vesa.c>

/*
 * TODO:
 * - PanelID might give us useful size hints.
 * - Port to RANDR 1.2 setup to make mode selection slightly better
 * - Port to RANDR 1.2 to drop the old-school DGA junk
 * - VBE/SCI for secondary DDC method?
 */
... snip ...


Is there any means to use the external monitor with vesa driver?
