I am in the process of setting up an HP Pavillion S5120f.
I have installed Fedora Linux 11 along with Windows Vista. It is a 64
bit AMD machine with 4 GB of memory. The current monitor is a simple
Dell 17-inch LCD. (Eventually I will switch to a better monitor.) It
has Brightness and Contrast controls as well as color controls. With an
Eye One Pro, I used
dispcal -yl -o -v -p 1,.5,.8 TargetA
leaving the brightness and contrast at default values which resulted
after calibration/profiling in a luminance of about 130 cd/m^2. I used
the color settings under option 2 tio get R=, G=, B=.
That produced a profile for me, but the reported gamma was higher than I
wanted. So I tried
dispcal -yl -g 2.2 -o -v -p 1,.5,.8
leaving the previous settings for brightness, constrast adn R, G, and B.
I had to do it three times to get a profile. The first time it hung on
patch 13 of 64 under iteration 3, and the second time it hung on patch
26, eventually timing out and reporting a communication error with the
device.
I have used this Eye One Pro repeatedly on another (32 bit Dell)
computer without incident. Has anyone any suggestions about what the
problem may related to: e.g, the 64 bit system, the particular USB port,
or what?
