Where can I download updates for the live-usb?įor now I don't understand the physics right, help appreciated :-) So I can only investigate on my older laptops / HTPC within virtual machines. One further point: the delivered live usb seems to only boot on EFI enabled systems. Whitepoint on my Toshiba LCD TV reports 10.000K - that is also far to high! (measured on a virtual machine).profiling only: BUROSCH test image shows *much* too less saturation in the blues ("gray with tint").rotating colorhug in 45° steps changes measured whitepoint max.measuring whitepoint with "colorhug display analysis" and "dispcalgui report on uncalibrated device": 12.000K.my display: Laptop, Sharp IGZO panel, mate, 3200x1800px, see attached profile from EDID.But the calibration resulted in a strong red shift, loosing a lot of display brightness (see attached profile). EDID claims native whitepoint with 6500K, so I did not expect a "dramatic" calibration curve. So my first step was to calibrate my screen with a target color temperature of 6500K. The new sensor type (mazet interference?) should directly output XYZ data according to standard observer CIE1931. I did order it, to overcome some issues with my colorhug(1) device (redshift, which I can only get rid of by using the EDID autogenerated ccmx - latter are not available for all my displays.)īut till now, I had no luck with the new colorhug2. I can see it definitely landing in Ubuntu 21.10, but 21.04 closes for new packages late this month for beta freeze.A view days ago, I received my new colorhug2. I'm a MOTU with Ubuntu, so I'd be happy to handle packaging and upload it. You might consider a different name for a proper fork (if necessary or if he doesn't accept your contribution, as he seems to not be interested in anyone else contributing) since, per that GPL at least, forks aren't allowed to carry the same name unless the original author has completely handed over the original project. The only issue that I can see is that you are keeping the name Displa圜AL. He seems to be only concerned with Windows and Arch, which means everyone else suffers.Īnyhow, I'm the leader of Ubuntu Studio, and as a photographer (among other things), it has been immensely frustrating for me to not have Displa圜AL available to myself and my users. He hasn't even addressed Debian and Ubuntu dropping the Python2-based dependencies, or that various distributions have dropped Displa圜AL due to the lack of those dependencies. Hi there! Not so much an issue as I wanted to thank you for taking-on this project since the Displa圜AL author isn't willing or motivated.
