Hi,
I'm having some issues in using my CH2. Here's a brief history of what I did.
I
bought the CH2 maybe two years ago and it worked like a charm up to the
past month, when I tried it on a new laptop (thinkpad t460s) and began
having issues.
First of all I was unable to make it work with
dispcalGUI under arch linux as I kept receiveing an "intrument access
failed" (like in [1]), I solved this by downgrading aryllcms to 1.8.3.
Then
I tried to calibrate my monitor, but the resulting calibration was way
too red (I've been using CH2 for more than one year, I know that 6500K
are more red than usual, but this was really too much).
When running colorhug-cmd get-calibration I got the following matrix:
0.64 -0.06 -0.02
0.03 0.63 -0.02
-0.11 0.05 0.78
I tried to colorhug-cmd reset and colorhub-ccmx --repair, but then I obtained the following matrix:
( 0,00 -0,06 -0,02 )
( 0,00 0,00 -0,02 )
( -0,11 0,00 0,00 )
Which is wrong.
I updated the firmware to 2.0.7 with fwupdmgr and reset again the matrix, with no change at all.
If I run colorhug-cmd get-multiplier (and many more commands) I get the following error:
usb:00:04: Invalid read: retval=0x01 [Unknown command] cmd=0x03 [get-multiplier] (expected 0x3 [get-multiplier]) len=64 (expected 3 or 64)
What can I do to restore it?
Thanks in advance!
