[Lazarus] gdk_gl_context_share_new no visual found

[Andrea Mauri]

Thanks Mattias, I will ask for the output of glxinfo and if they are 
running the application remotely or locally.
Anyway they also wrote me that the application worked till last week and 
now they got this error message. What can affect this modified behaviour?
