Hello. Opening examples from pyqtgraph.examples. run (). Everything works except 3D.
Part of the example:
******************************
from pyqtgraph.Qt import QtCore, QtGui
import pyqtgraph.opengl as gl
app = QtGui.QApplication([])
w = gl.GLViewWidget()
w.opts['distance'] = 200
w.show()
w.setWindowTitle('pyqtgraph example: GLVolumeItem')
******************************
Outputs this:
******************************
qt5ct: using qt5ct plugin
bind: Invalid command `enable-meta-key'.

I've been working with Raspberry and Linux for a couple of months, so the question may be silly.
What could be the problem?

There is actually an open issue for this, there won't be any fix we can implement in the library, as I don't think there exists a change pyqtgraph _can_ make; but the issue details some of the criteria needed to be met for 3D graphics to work on it:
