cpu loadf.lux
I installed f.lux on Ubuntu 14.04.
The GUI doesn't work properly but I am able to access settings through the xterminal. While looking in the system monitor, it can be seen that a process called "xflux" is using 100% of one one the cpu cores.
Is there a fix for this issue?
As suggested by Cedric Julien in the comments,
To view all the processes that are using CPU, when using System Monitor, go to the View menu and select All Processes
Take a look and delete all files in /var/crash/:
rm /var/crash/*
I suddenly had the same problem apport-gtk taking 100% on every restart.
Seemed there was a huge (2GB+) bogus crash file in /var/crash/ that couldn't be parsed. After several minutes of waiting I always ended up with this rather mysterious dialog:
This problem report is damaged and cannot be processed. Error('Incorrect padding',)
After I deleted the file in /var/crash/ both issues were gone.
Best Answer
From reddit simply reinstalling F.lux solves this problem.
