[scilab-Users] Error while performing remote login: X11 connection rejected because of wrong authentication

[Sylvestre Ledru]

Looks like a configuration problem on your side. I just tested to start
Scilab this way and it works.

You can try to force software acceleration if it fixes your graphic
issues with intel:
system_setproperty("jogl.gljpanel.nohw","");
