My Video Card is Matrox MGA450, dualhead.I try to use Agryll CMS to load ICC profile. First I trieddispwin -rThe result is We don't have access to the RAMDACI would greatly appreciate any help with this. This is ltrace output (perhaps this could be useful):
The other thing to do is turn DEBUG on in dispwin.c and recompile. Judging from the trace though, one explanation is that the number of entries in the RAMDAC doesn't match the screen depth. Perhaps you haven't set your display to a 24 bit depth visual ? There's really no point in trying to calibrate a display unless it is at least running 24 bit, and I've no idea how a less than 8 bit per component frame buffer is wired to a 256 entry RAMDAC.
