I have installed Kubuntu 64bit on my MBP 7,1. After installation I was going through following documentation (screen) https://help.ubuntu.com/community/MacBookPro7-1/Maverick#Screen I am confused about line /usr/bin/xcalib "/etc/xcalib/<insert name of profile here>" which profile to put at that place? I am getting following output on command prompt bharat@bharat-MacBookPro:~$ ls /etc/xcalib Color LCD-00000610-0000-9CC5-0000-000004273140.icc EPSON PJ -00004CA3-0000-A600-0000-000028E98001.icc SyncMaster-00004C2D-0000-0117-4C45-31370B4074F5.icc
