#StackBounty: #upgrade #xcalib xcalib stops working at random Ubuntu 18.04

Bounty: 50

I have just upgraded my ubuntu (Ubuntu 18.04.2 LTS, bionic). I am using xcalib -i -a to reverse the colors of my screen. Unfortunately, since the upgrade, something seems to have broken: xcalib stops working at random (and this is a little nightmare for my eyes). I don’t really know which information is relevant for this question. Here are the last modules installed (obtained with : find /var/lib/dpkg/info/ -name *.list -mtime -3 | sed 's#.list$##;s#.*/##' ) :

xzoom
libmng2:amd64
libnss-systemd:amd64
libgimp2.0
libkf5kdelibs4support-data
curl
libpam-systemd:amd64
systemd

If someone has an idea, I would really appreciate. A little detail : when xcalib stops, I run it again with a shortcut of mine and it stops immediately again. When I use again the shortcut, it waits approximately one minute to stop again. 🙁

Thanks in advance.


Edit 23/02/2019 : the problem did not disappear, and this is still a nightmare. 🙁 🙁 🙁 I’m starting to loose hope. I removed and reinstalled xcalib, with no effect of course. Right now, I am trying to see which processes appear (in top) when I keep changing the color of the screen.

Potentially linked due to activity : irq/71-brcmf_pc (by the way, I have a mac with Ubuntu installed on it, I should have precised that from the start ; this is my professional laptop, I couldn’t choose :[ ), iio-sensor-prox, colord, gsd-xsettings, gsd-media-keys, gsd-clipboard, at-spi2-registr.

I had a look on the internet to see what these processes were doing, but I have not a single clue. So, I start a bounty.
