Since my posts never make it back to me for some unknown reason I'll
have to again reply to this. While I was gone this morning and the PC
was idle, no applications were being started/stopped, the modeset info
was written to syslog:

Nov 21 10:32:20 localhost /usr/lib/gdm3/gdm-x-session[2285]: (II)
modeset(0): EDID vendor "ACR", prod id 22
.....
Nov 21 10:32:23 localhost /usr/lib/gdm3/gdm-x-session[2285]: (II)
modeset(0): Modeline "1280x720"x60.0

It was actually written 4 times in 3sec.
