livecd calibration failed on Thinkpad X230

[tigert]

So I tried to use the livcd and it also fails further down the road:

Can I debug this somehow to give you a better idea of what goes wrong?

[hughsie]

Very much so, can you do:

killall colord-session
/usr/libexec/colord-session --verbose

Then launch the calibration and get it started. When it fails, can you paste the full log from the terminal. Thanks!

(This is from my Fedora 24 laptop install, I'll do the same from the LiveUSB next)

I get a similar error with colord 1.3.3 and GNOME 3.22 on Arch.

Still the same error with 1.3.4. I tried to capture the USB traffic, maybe this helps.

When I'm interpreting the firmware correctly, the CH_ERROR_INVALID_VALUE comes from ChSha1Valid. Will CH_EEPROM_OFFSET_REMOTE_HASH ever be set before colord tries to read it?

[hughsie]

I think the error handling of the "unset hash" has changed; can you try the 2.0.7 firmware here and tell me if it helps please: https://secure-lvfs.rhcloud.com/lvfs/device/2082b5e0-7a64-478a-b1b2-e3404fab6dad

[svenpilz]

Yes, now it's able to calibdate. Thanks :).

[tigert]

Hmm. Looking into this again. Fedora 25 now. Wayland too I think. Flashed with 2.0.7 and it got further.

Note for those attempting to flash the firmware: the colorhug-flash command expects a .bin file, the .cab needs to be unpacked with cabextract, flashing the above downloaded file directly won't work.

Managed to calibrate laptop screen, but external Dell screen does not work - now it proceeds further but fails with an error saying it could not complete calibration. The colord-session output: https://paste.fedoraproject.org/525401/

I wonder if it could be related to the dual monitor thing - I have to disable the laptop screen because if I have both on, calibration window appears always on the internal monitor. ( #26 )
