What is xiccd and why is it using so much CPU?

Hello,

I just upgraded from Debian and xiccd was installed.

I only noticed it because it's taking 100% of one of my cores.

What is this process? Is it a known bug that it's taking 100% CPU?

I'm running Debian "testing", with Xfce 4.14. xiccd is version 0.2.4.

https://docs.xfce.org/xfce/xfce4-settings/color

It seems to be a daemon to apply display color profiles. Try maybe to kill it and see if it can be disabled at the startup settings.

Here in Fedora it seems we still don't have it, but if it's not working so well maybe it's for the better.

Googling the first half of your subject line "what is xiccd" leads to this helpful page:

http://manpages.ubuntu.com/manpages/bio … ccd.8.html

We just installed it so that Color Profiles would work, but no one has reported the racing you have seen.

I see this 100% CPU usage about 1 in 5 sessions.

It is easy to kill manually, doing so seems to have no effect.

But it is definitely a problem burning up system resources until you notice it.

I can report the same issue on my laptop with Linux Mint 19.3 Xfce on it... :-(
Can I safely disable it within "Session and Startup"?

Hi FoxiMaxi, and welcome.

That's a new issue for some with Mint 19.3 Xfce. There are a few ways to solve it in this thread: https://forums.linuxmint.com/viewtopic. … 9#p1735575

The gist of the issue is that xiccd isn't stopping when logging off and a new one starts up when logging back on and the original copy runs up to 100% CPU usage. The newer xiccd has fixed this, but Ubuntu based distros don't get the newer xiccd even on Eoan.

uninstall the xiccd and you will no longer have problems.
sudo apt-get purge xic cd

sudo apt-get purge xic cd

But then you will lose the functionality that it provides. I believe MrEen identified the issue, so there is a workaround.

Welcome to the forums, BTW.

Re: What is xiccd and why is it using so much CPU?

There's a known bug in xiccd that's been there for years: if you log out and log in again (or switch user), the demon will take 100% CPU. It happens only with some DEs, including Xfce.

A workaround when it happens is to open a terminal, kill it (killall xiccd) then restart it (xiccd &) and exiting the terminal.
