Hiding Xvfb Teminal Logs

Question

Every time I execute my tests in headless firefox using Xvfb I get large chunk of logs. These logs display different parameters and their values .

I was wondering if I can disable these logs somehow, I googled a bit but could not find anything useful

Following logs are displayed and I want to disable these.

Same problem here. Did not find a clean solution to disable them so I included a pre-build task in Jenkins to clean those log files before running the automated tests. And as my automated tests are launched very regularly by Jenkins, logs are often cleaned. This way I don't risk any disk-full issue.

There are a number of ways to resolve this problem. I would first suggest initializing Xvfb in a separate terminal from where you're running your code. Xvfb log messages will be dumped in the terminal it's running in.

Another solution would be to use a wrapper. If for example you're coding in python, you could try https://github.com/cgoldberg/xvfbwrapper

You can get those Verbose messages to go away if you re-direct the log output from Xvfb to /dev/null.

In my case, I was using Xvfb plugin in Jenkins and running Selenium tests using Firefox on a CentOS machine. Got the same verbose messages.

I resolved it by UN-CHECKING one of the box which was for "Logging Xvfb log output" --OR

you can also do it as at the $ or # prompt:

/usr/bin/Xvfb :99 -ac -screen 0 1600x1200x16 2>/dev/null 1>&2 &
