Have a read here http://www.freedesktop.org/software/colord/faq.html which a quick google dug out.
Basically the position was that the Nvidia proprietary driver needed for openCL acceleration only supported the old and somewhat obsolete XrandR1.2. Gnome color management however required XRandR1.3 to function properly and worked with the Nouveau drivers Ubuntu configure by default but not the proprietary driver. Looking at the current faq page which I linked the restriction might now but only for multiple displays - which would be nice as for many of us it would make Nvidia displays fully usable again. When I next need another graphic card I'll research it properly again ... -----Original Message----- From: Pascal Obry [mailto:[email protected]] Sent: 09 June 2014 11:10 To: [email protected] Subject: Re: [Darktable-users] Fwd: Graphics-card compatibility question Rob, > At the moment I am using an AMD card due to the absolute nonsense of > there being no Nvidia driver which supported both the opencl > acceleration needed for darktable and the X versions needed for > driving the monitor calibration devices you need for a colour managed > setup.

I'm using GNU/Debian with the proprietary driver (installed using nvidia-kernel-dkms package) and I have an accelerated X (GNOME Shell here) and OpenCL available for darktable. I have no issue with color management, I have used a ColorMunki and a Spider devices, no issue. And the situation above is true for me since at least 5 years! -- Pascal Obry / Magny Les Hameaux (78) The best way to travel is by means of imagination http://v2p.fr.eu.org http://www.obry.net gpg --keyserver keys.gnupg.net --recv-key F949BD3B ------------------------------------------------------------------------------ HPCC Systems Open Source Big Data Platform from LexisNexis Risk Solutions Find What Matters Most in Your Big Data with HPCC Systems Open Source.
