QuantumATK Problems on Ubuntu

QuantumATK has problems on Ubuntu, like fails to start up, or freezes immediately after startup, or is unable to show the 3D graphics windows properly. Solution:

  1. Disable “compiz” and use the Ubuntu Classic window manager without effects (detailed instructions).
  2. Run “qtconfig” and select GUI Style = “Cleanlooks” (or something else - just not “GTK+”)

You may need to apply both - or only one - of these fixes, depending on your setup.


There are many reported problems on the incompatibility between compiz and Qt apps, so this is not something we can fix in QuantumATK. See for example:
