red drop shadow

[cedric]

Hi,

Just received a ColorHug 2. I've tried to calibrate my laptop screen with the gnome colour manager and I'm getting a red drop shadow when I moving the mouse cursor or any kind of windows/ objects.

Additionally I've used DisplayCal 3.1.6 (Argyll 1.9.1) and I can't get a successful calibration (after few seconds/ minutes):

dispread: Error - new_disprd failed with 'Instrument Access Failed'

What do I need to use for the "mode" during the first calibration? ...auto/ LCD/ Factory calibration ?

Cheers,

that's pretty normal, if the video card hardware doesn't run the cursor overlay
data through the VideoLUT tables i.e. not much that can be done about it
short of:

* Adjusting the native display controls to be closer to the white point you are after or
* Fixing the display card driver to correct the cursor pixmap through the VideoLUTs or
* Fixing the display card hardware to run the cursor overlay planes through the VideoLUTs or
* Manually modifying all the cursor pixmaps you use to be pre-corrected by the calibration
curves.

I tested both Colorhugs 1 & 2 with V1.9.1 on Linux before release, and both
seemed to work, so I'm not sure why it isn't working for you. A -D8 debug
trace may give a clue. (I'm presuming you at least tried un-plugging and
re-plugging it a few times ?)

You should select a display type that best matches your display.

any pointers with the DisplayCal GUI to achieve this?

out of my ability to do that... :-)

I'll report later with the debug logs

On the "calibration" tab, you can set a different whitepoint target. But
in my (limited) experience with them, the ColorHug devices seem not
accurate enough to reliably approximate the commonly used targets (i.e.
6500K or 5000K) within acceptable tolerance (when compared to a
spectrometer, for example), even though the CH2 is a marked improvement
over the CH1. A way around this is to use the native display whitepoint
as target instead ("As measured"), and this would be my general
recommendation when using a ColorHug if you don't have the need to match
a specific reference (e.g. another display or a viewing booth).

ok so just leave the default values

So the ArgyllCMS driver did a "GetFirmwareVersion" command, and the
ColorHug didn't reply - the USB read timed out. Seems like
something strange going on with 1) The ColorHug or 2) The USB port or
3) The Linux USB drivers.

I'm using a quite recent Linux kernel 4.7.5 and I've got only 2 USB 3.0 ports on my laptop.

[cedric]

I've tried connecting the ColorHug with a USB 2 hub and same issue...  can I have a refund please... :-) 

[Richard Hughes]

Yes. Send the device back to us and Ania will process the refund.
