Hi, I am a bit confused as to why dispwin refuses to load the profile when run as a regular user whereas xcalib will do it. xcalib is not SUID root.... Ubuntu 8.10 (had no Problems on SuSE 11.1) --------------------------------------------- $ /opt/Argyll_V1.0.3/bin/dispwin -v -I /usr/share/color/icc/T61.icc About to open dispwin object on the display About to install '/usr/share/color/icc/T61.icc' as display's default profile Dispwin: Error - Failed to install profile '/usr/share/color/icc/T61.icc'! $ xcalib /usr/share/color/icc/T61.icc $ ls -l /opt/Argyll_V1.0.3/bin/dispwin /usr/bin/xcalib -rwx--x--x 1 root root 611478 2008-09-04 01:13 /opt/Argyll_V1.0.3/bin/dispwin -rwxr-xr-x 1 root root 22816 2008-07-18 15:49 /usr/bin/xcalib ------------------------------- And yes, I can clearly see the effect of the LUT loading from xcalib. thx afx -- http://afximages.com/
