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 pciutils gimp-data libbabl-0.1-0:amd64 libkf5kdelibs4support5:amd64 systemd-sysv libgegl-0.3-0:amd64 libnss-myhostname:amd64 libsystemd0:amd64 libcurl4:amd64 udev libpci3:amd64 libudev1:amd64 libkf5sane-data gimp libcogl20:amd64 libkf5sane5 duplicity libcogl-pango20:amd64 kolourpaint gir1.2-coglpango-1.0:amd64 libkf5kdelibs4support5-bin gir1.2-cogl-1.0:amd64 gdm3 initramfs-tools initramfs-tools-core initramfs-tools-bin libgdm1 libcogl-common gir1.2-gdm-1.0 libcogl-path20:amd64 libcurl3-gnutls:amd64 gnome-software-plugin-snap libvulkan1:amd64 pop-gtk-theme gnome-software gnome-software-common ubuntu-software
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 :[ ),
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.
