Vesa driver, dispwin was complaining about broken xrandr support. Thus, I guess it is using xrandr. I'll check if I can find anything to monitor
If dispwin is complaining about broken XRandR support, then it is not using it. So that tends to eliminate XRandR as a culprit. I'm not sure if you would get the behaviour you see if any of the needed X11 extensions are not being loaded (ie. extmod). A desktop component that is constantly loading the Video LUTs is still a possibility. Maybe you could fire up a naked X11 session (no desktop components, just the X11 server - I'm not sure how you do this) and see if things behave differently. Graeme Gill.
