Python spyder could not initialize GLX

Problem:

Whenever I run spyder, It results in the error below

QXcbConnection: Failed to initialize XRandr 
Qt: XKEYBOARD extension not present on the X server. 
Could not initialize GLX
Aborted (core dumped)

Solution:

1、Simply try:

export QT_XCB_GL_INTEGRATION=none

Then, start the spyder

 

2、Reinstall some packages:

sudo apt-get install libgl1-mesa-dri
sudo apt-get install --reinstall xserver-xorg-core libgl1-mesa-glx libgl1-mesa-dri
sudo dpkg-reconfigure xserver-xorg
