libGL error: MESA-LOADER: failed to open crocus

[Michel Keyaerts]

Hello,

I am new to kivy. I am testing example codes. When I launch the app, nothing happens and  I get the following errors:

libGL error: MESA-LOADER: failed to open crocus: /usr/lib/dri/crocus_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri)

libGL error: failed to load driver: crocus

libGL error: MESA-LOADER: failed to open swrast: /usr/lib/dri/swrast_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri)

libGL error: failed to load driver: swrast

X Error of failed request: BadValue (integer parameter out of range for operation)

Major opcode of failed request: 149 (GLX)

Minor opcode of failed request: 3 (X_GLXCreateContext)

Value in failed request: 0x0

Serial number of failed request: 80

Current serial number in output stream: 81

Here is the initial code:

import kivy

kivy.require('2.0.0') 

from kivy.app import App

from kivy.uix.label import Label

class MyApp(App):

       def build(self):

            return Label(text='Hello world')

if __name__ == '__main__':

       MyApp().run()

WHat could I do?

 I have

/usr/lib/dri/crocus_dri.so

and

/usr/lib/dri/swrast_dri.so

on my computer

Many thanks,    Michel

I suspect and installation error.  I have not done an install on Linux. 

Make sure you follow the directions here: https://kivy.org/doc/stable/gettingstarted/installation.html#install-pip

And ensure your graphics driver is up to date.

Thank you for your answer,

If I remember correctly I had installed kivy via anaconda: conda install kivy -c conda-forge

For the graphic drivers I'm not sure. I just upgraded all my system. The problem is still the same.

In fact, a few weeks ago, kivy was working fine; I think I had problems after installing kotlin and android studio but I'm not sure
