Ubuntu 23.10 - Display color calibration problem

  • 772

I'm trying to adjust the color calibration for my LCD video display.

I purchased a Datacolor Spyder X Pro colorimeter which is supposed to be supported.

I installed argyll 2.3.1 and its support files, colord-sensor-argyll 1.4.6-3, icc-profiles 2.1-2, gnome-color-manager 3.36.0-2, and displaycal 3.9.11-1.

I open Settings and go to the Color section, select my display, and click on the calibrate button. I go through the following steps... enter image description here enter image description here enter image description here enter image description here enter image description here enter image description here

And here's where I get stopped. Where is the Start button?

Update #1 - 2/21/24:

This appears to be a bug that goes all the way back to Ubuntu 22.10. I'm told that it works fine in 22.04, but I haven't verified that yet.

Post note: I just installed 22.04 in a Virtualbox VM, and the Start button appears, when it should, during calibration.

Update #2 - 2/22/24:

After implementing the patch from the answer by Daniel T (thanks BTW), it does now get a "Start" button, but after clicking it, the color patch remains white, and it errors out with "internal error".

See the following information from the terminal, and syslog.

Update #3 - 2/22/24:

Here's the screenshot that Daniel T's patch created...

Update #4 - 2/22/24:

After installing gnome-color-manager, DisplayCAL worked. GNOME Settings still fail.

  1. It is possible to make the start button show up:

    mkdir askubuntu_color_calibration_fix
gresource extract /bin/gnome-control-center /org/gnome/control-center/color/cc-color-calibrate.ui |
    sed 's/ internal-child="action_area"//' > askubuntu_color_calibration_fix/cc-color-calibrate.ui
export G_RESOURCE_OVERLAYS="/org/gnome/control-center/color=$(realpath askubuntu_color_calibration_fix)"
# export GTK_DEBUG=interactive
gnome-control-center

    When the Settings app is launched this way, it should show the Start button. For me, GNOME doesn't let me click Calibrate without a colorimeter leaving me to use GtkInspector and set the window to visible, which may look different from a normal system:

    gtk inspector display calibration

    The problem is caused by the port to GTK4 being untested. The row that holds the button is supposed to be there, but GTK4 doesn't understand the unnecessary internal-child attribute. The action_area value doesn't seem to be used by the code. I just patched it out and injected it with a GResource overlay.

    I installed argyll 2.3.1 and its support files, colord-sensor-argyll 1.4.6-3, icc-profiles 2.1-2, gnome-color-manager 3.36.0-2, and displaycal 3.9.11-1.

    Even after @DanielT's patch, and the Start button re-appeared, the GNOME Settings still failed to calibrate. I tried some older Ubuntu versions (23.04, 22.10), with the same problem. I'm told, but haven't verified it, that 20.04 would work.

    Post note: it works in a 22.04 VM.

    Let's hope they fix this in the upcoming 24.04 (along with the busted backlight code, and the GNOME Shell restart crashes).

    I tried DisplayCAL and it worked.
