Update: The button itself is tested to properly show up now. However, it's whether the whole process works. An `sudo apt install gnome-color- manager` may be able to fix that.
# https://askubuntu.com/questions/1504329/ubuntu-23-10-display-color- calibration-problem#comment2639103_1504361 @DanielT I just retried displaycal, only this time I went all the way to the end... and it failed... and the terse error looked like it was complaining that it couldn't communicate with the color-manager, so I installed gnome-color-manager and then displaycal worked properly when rerun. – heynnema 32 mins ago # Updated question https://askubuntu.com/q/1504329/1004020 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. 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. ``` al@al-Inspiron-7700-AIO:~/Desktop$ sh askubuntu_color_calibration_fix.sh 09:18:10.5465 cc-color-panel[18961]: WARNING: calibration failed with code 1: Timeout was reached al@al-Inspiron-7700-AIO:~/Desktop$ cd /var/log al@al-Inspiron-7700-AIO:/var/log$ tail syslog 2024-02-22T09:18:26.993688-08:00 al-Inspiron-7700-AIO ubuntu-report[3390]: level=error msg="data were not delivered successfully to metrics server, retrying in 120s" 2024-02-22T09:18:35.407512-08:00 al-Inspiron-7700-AIO systemd[3355]: Started app-gnome-org.gnome.Settings-19159.scope - Application launched by gnome-shell. 2024-02-22T09:18:35.707775-08:00 al-Inspiron-7700-AIO gnome-shell[3900]: Window manager warning: Buggy client sent a _NET_ACTIVE_WINDOW message with a timestamp of 0 for 0x2c00004 2024-02-22T09:19:21.000134-08:00 al-Inspiron-7700-AIO gnome-shell[3900]: Can't update stage views actor <unnamed>[<MetaWindowActorX11>:0x56149c6b1f90] is on because it needs an allocation. 2024-02-22T09:19:21.000796-08:00 al-Inspiron-7700-AIO gnome-shell[3900]: Can't update stage views actor <unnamed>[<MetaSurfaceActorX11>:0x56149e0ec310] is on because it needs an allocation. ``` Post note: I have a Dell AIO with a touch screen. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/2043119 Title: screen color calibration : no start button Status in gnome-control-center package in Ubuntu: Confirmed Bug description: I try to calibrate my screen using the utility of gnome-control-center, color section. I have a Spyder3 Express probe connected by USB and the Calibrate… button become active. So I click this button and the process begin with a dialog box giving several informations until it ask for the name of the further colour profile. After that, a small window appears asking to put the probe on this window and to press "Start"… but there is no Start button. I tried the same on Ubuntu 22.04 (on a VM) : the same window occupied all the screen and we can see a Start button at the bottom right and a Cancel one on the bottom left.
