Description Gerold Jens Wucherpfennig 2012-10-30 12:30:43 UTC

In systemsettings->Hardware->Display->"Size and Orientation"
there can be configured two displays: first LVDS-1, that is
the display screen of my laptop and second VGA-1 that is
my external display. Xinerama etc. all work fine...

In "systemsettings->Hardware->Color" though there is only the first
display shown when all two displays are enabled. Changing
the color profile is only possible for first display. When disabling
the first display, the second (external) display appears in
"systemsettings->Hardware->Color". Only when reenabling the
first display screen all two displays can be configured.

Another problem:
On the laptop display screen the "Calibrate" button is disabled,
but on the external display caliberating is possible, the
"Calibrate" button can be clicked at.
(On the software liveCD which was included by my ColorHug
calibration of both display screens was possible!)



Reproducible: Always

Not reproducible with nouveau and intel systems and two monitors. Going to systemssettings->"Appearance and Behaviour"->"Color Management"->"Devices"  all Xinerama screens are shown. The "Color Management" panel has no calibration button. 

Profiling and eventually calibration can be done inside external applications like dispcalGUI.

Comment 2 Gerold Jens Wucherpfennig 2012-10-31 07:03:57 UTC

The computer is a Laptop, only its display is shown. The driver is nouveau.
An external display is conneccted via VGA. Both displays have a 1920x1200
resolution, the display content is cloned.

Comment 4 Kai-Uwe Behrmann 2012-10-31 07:39:46 UTC

That bug appears colord-kde related, which explains why I can not reproduce this bug. I tr y to inform the colord-kde maintainer Daniel Nicoletti.

KolorManager is a different project.

Hi, we are working on the issue, I still don't know what causes the EDID data of the monitors to be null at KDE startup, but here is a workaround:
pkill kded4; kded4
Killing the kded4 process and starting it up again from command line fixes the issue.
I'll reasign the bug as soon as we have a colord-kde component, and update once we properly fix it.
Thanks

Git commit a3307c670055104afdce5d2d2714db47479fb5aa by Daniel Nicoletti.
Committed on 27/11/2012 at 15:17.
Pushed by dantti into branch 'master'.

This fixes a bug that made the color profile not to be applied on
startup and also left the device-id empty, due to a call that
only got cached values from X which on session startup didn't had
the EDID data for the outputs set.
It also fixes a bug that failed to emit output changed when
an external monitor was plugged in.

There is a package in Ubuntu proposed now, you can test and if it works please input your experience there so it can be available as an update:
