Correct, the Quadro NVS 110M a relatively new GPU. It won't be moved into a legacy branch for a long time. > But the default setting > on my laptop could not detect the projector at all.

There are two levels of device detection. If the driver sees a normal current load on the RGB lines on the M5 VGA port, the "Detect Displays" button will put up a display rectangle. If EDID can be read, it will identify the display and set up the correct video modes.
However, this behavior depends upon setting the SBIOS correctly. In you SBIOS (keep hitting the Esc key right after the screen resets on a reboot until it tells you to hit the F1 key) on page 2 (PgDn key) the Display -> Power On Display must be set to "LCD+Analog RGB". The default is "Auto-Selected" which will not work well with nvidia-settings hot plug detection. (My M5 has SBIOS 3.60). If your SBIOS was still at the default, change it and get rid of /etc/X11/xorg.conf and try again.
