libdri is usually bundled with the X server.  Clearly you are loading libdri
version 5.0; your 2D driver must be updated to deal with that.

- ajax

Can someone help me to do that ? How can I see the version of my 2D driver ? How can I update it ?

If I upgrade Xorg, would the 2D driver be updated ?

Thank you for your help.
