Whenever i open matlab i see following error message. I am also not able to draw graph in matlab due to this issue. I am using a debian machine with nvidia graphics card.

This is the MATLAB error:

com.jogamp.opengl.GLException: X11GLXDrawableFactory - Could not initialize shared resources for X11GraphicsDevice[type .x11, connection :1, unitID 0, handle 0x0, owner false, ResourceToolkitLock[obj 0x5f72428a, isOwner false, <5219f6a5, 1e2957ef>[count 0, qsz 0, owner <NULL>]]]

Hi,

Try executing one of the following commands in debian shell to start MATLAB

• matlab -nodesktop -r "opengl info, desktop"
• matlab -softwareopengl
• matlab -noopengl

Your issue might be similar to this know issue.

Contact support if above workaround doesn't work for you.

Thanks.
