Hi all, I am trying to calibraty my monitor using a sypeder 2 and dispcal argyll and I get a "Instrument Access Failed" error. I attach the log of running 'sudo dispcal -v -q l -y l -D 9 dell'. The OS is a Ubuntu 10.10 64 bits. The spyder is attached directly to the computer. Previously I've succeded using the same spyder 2 with another computer (a laptop) with Ubuntu 10.4 32 bits. Any idea where is the problem? Thanks, jordi.
