rtcqs, pronounced arteeseeks, is an attempt to rewrite raboof's excellent realtimeconfigquickscan script in Python.


Basically the same as realtimeconfigquickscan:

  • Root check
  • Audio group check
  • Background process check
  • CPU frequency check
  • High resolution timers check
  • System timer check
  • Preempt RT check
  • rtprio check
  • Swappiness check
  • max_user_watches check
  • Filesystem check

Additional features:

  • Spectre/Meltdown mitigations check
  • Basic IRQ check of sound cards and USB ports
  • Power management check
  • Qt GUI


When writing this script I could rely on Python's built-in functionality so no extra modules are needed, just Python 3. To run the script first clone this repository.

git clone https://codeberg.org/rtcqs/rtcqs.git

Then cd into the newly created directory.

cd rtcqs

And run the script.



To run the GUI first install the PySimpleGUIQt module either in your home directory or a virtual environment.

Home directory

Make sure pip is installed, on Ubuntu this would be the python3-pip package. Then install PySimpleGUIQt for your user.

pip install PySimpleGUIQt

Virtual Environment

Make sure the virtual environment module is installed, on Ubuntu this would be python3-venv. Then create a virtual environment in the rtcqs directory and install PySimpleGUIQt in there.

python3 -m venv venv &&
. venv/bin/activate &&
pip install --upgrade pip setuptools PySimpleGUIQt

You can now run the GUI with ./rtcqs_gui.py. Next time you'd like to run the GUI load the virtual environment again and spin up the GUI.

. venv/bin/activate


When running the GUI it will immediately show the results of the checks. All checks have their own tab. Each tab title consists of a symbol that shows the check result and the name of the check. A ✔ means the check was successful while a ✘ means rtcqs encountered an issue. This way you can quickly spot which checks have issues.

Clicking 'Cancel' will close rtcqs. Clicking 'About' will bring up a popup window which displays the version and a short description.

Future plans

  • Make the project more dynamic and modular so it gets easier to add new features

Many thanks of course to the original author of realtimeconfigquickscan, Arnout Engelen a.k.a. raboof.
