displaycal fails to install ICC profile via colord on XFCE.

[Anonymous]

I’m on ArchLinux. xiccd is currently running as a bridge between X and colord. The output of colormgr get-devices is shown below.

When I try to install an ICC profile in displaycal GUI, I get the following error message.

colord: device id 'xrandr-Arithmos,-TLED24HDTV-16843009' does not exist

How can I fix this error?

This can happen if colord and DisplayCAL don’t agree on the vendor ID database to use, and/or the databases are not synchronized (contain different entries). Both should normally use 20-acpi-vendor.hwdb (usually located at /usr/lib/udev/hwdb.d/20-acpi-vendor.hwdb) or pnp.ids. You can check those files to see if one of them doesn’t contain an entry for Arithmos to figure out which one colord is using (if any at all). The next step is then to sync the databases (i.e. installing the newest version of each), or figure out why colord doesn’t see the entry.

In /usr/lib/DisplayCAL/pnp.ids, I found ADE Arithmos, Inc..

In /usr/lib/udev/hwdb.d/20-acpi-vendor.hwdb, I found

acpi:ADE*:
ID_VENDOR_FROM_DATABASE=Arithmos, Inc.

I couldn’t find problems in those files.

xiccd registers xrandr-TLED24HDTV-16843009 to colord, and the calibrated profile made by DisplayCAL contains MAPPING_device_id : xrandr-Arithmos,-TLED24HDTV-16843009. I suspect DisplayCAL constructed a wrong device id for the profile.

Better ask on the colord mailinglist why the device ID doesn’t contain the vendor name as per the specification[1] then.

I suspect DisplayCAL constructed a wrong device id for the profile.

From what I can see, it’s actually colord that is not adhering to its own spec…

By the way, after I make a new calibrated profile, if I let displaycal install the new profile, I see a different error message.

colord: Querying for profile 'icc-dcb94124d150c321f7a694e573947cd8' returned no result for 5 secs

If I try to install the profile after that error message, the error message is colord: device id 'xrandr-Arithmos,-TLED24HDTV-16843009' does not exist.

If I type colormgr get-profiles, I can see 'icc-dcb94124d150c321f7a694e573947cd8' in the list.

Alright, I probably need to increase the timeout when polling for the new profile. 30 seconds should do I think.

I doubt that 30 seconds would be sufficient. When I dig my faint memory, I vaguely remember that the profile didn’t appear after 30 seconds but appeared after a reboot. I don’t know if my memory is correct, but I have a doubt.

I think you should test displaycal with XFCE and xiccd.

[Florian Höch]

I doubt that 30 seconds would be sufficient.

The time that it takes for the session daemon to pick up on new profiles is usually counted in milliseconds, maybe a second or two in a worst case scenario, so I highly doubt it’ll ever take that long.

I think you should test displaycal with XFCE and xiccd.

Works perfectly fine here (XFCE under Debian). You should ask the xiccd or colord developers what’s up with vendor name missing (in your case) from the device ID, that is clearly an issue.

I confirmed that the profile installed by displaycal appeared in colord after a reboot. I haven’t tested whether a new profile appears in colord after logging out and logging in.
