Comment 41 for bug 1442050

Bug still exists on Ubuntu 16.04.6 LTS, Kernel 4.14.140. Found when looking for what was causing xrandr to reset screens to full brightness and gamma. Even if `colord` isn't culprit, life is easier with less spam in journalctl.

Ignore extra `s` in `fails` below (line wrap off) for bug report:

$ journalctl | grep "failed to get session \[pid"
