Dispwin (and also xcalib, actually...) loads the calibration profile correctly (i.e., no error messages and dispwin -V says that the loaded LUT matches with the one of the profile), but there is no visible change on the monitor when the profile is loaded. I can tell you for sure that, previously, you could easily notice a difference when you loaded the profile. I have also
Does anybody have an idea on how to solve this problem?
Sounds like a problem with the X11 server or driver not implementing the video LUT setting properly. It would be interesting to know whether dispwin is using XRandR 1.2 or the older mechanisms to set the video LUT (-v may give a clue). Conceivably it could be something other process resetting the calibration all the time, but off hand I'm not sure how you would determine this (I don't know enough about the modern desktop environments to know exactly what is a likely culprit, or whether it would be possible to trace all the X11 calls being send to the server. Maybe xtrace ?). Graeme Gill.
