I created and successfully installed some profiles using dispcalGUI, but have now run up against a problem I've not been able to solve. I can no longer install or uninstall any profiles using dispwin -I, -L, or -U. Following is the error I get with dipwin -E -I: Checking XRandR 1.2 VideoLUT access XRandR 1.2 is faulty - falling back to older extensions get_displays checking for Xinerama Display 0 name = ':0.0' Opened display OK dispwin_get_ramdac called lexical error: invalid bytes in UTF8 string. /display/LG 2009-06-30 120cdm² D6500 min neutral 2.2 HQ LUT. (right here) ------^ Installing profile '/home/samsoar/.local/share/color/icc/devices/display/LGflatronCalProf.icc' failed with error 7 'There was an error opening the config file' Dispwin: Error - Failed to install profile '/home/samsoar/.local/share/color/icc/devices/display/LGflatronCalProf.icc'! I'm guessing this is related to allowing diswinGUI to create and install a profile with special characters in the profile name. I can load and unload .cal files, but not install and uninstall profiles. My color managed apps no longer work with the installed profile either. I am out of ideas on how to fix this and am hoping someone can help. Video card is an Nvidia running the proprietary driver. TIA, Scott
