It isn't, the panel should be powered down as well (but I guess there isn't enough information how to do it). An undriven panel shows the effect called 'blooming', and while it's never seemed to damage any of my panels, I wouldn't count on that. > Try using generic fbcon blanking (line 2107 in drivers/video/riva/fbdev.c. > function riva_set_fbinfo, set info->blank = NULL instead of rivafb_blank). That won't save power either, but it's probably better than blooming indeed. > Do you get the same color when starting up X (right after console > switching, before the X default cross-hatch background pattern appears)? > I've been wondering about that one before.
