RE: vglrun display error with standalone conn
Hi Joseph,
I do not believe this is related to the XAPPLRESDIR environment variable, as far as I can tell that seems to be actually disregarded in recent MCR versions (older than 8.5 -2015-). Just a few general questions to see if I can better understand / reproduce this issue, could you please let me know:
1) which version of conn standalone are you using (and whether you compiled it yourself or downloaded a pre-compiled version)
2) which client software you are using (e.g. TurboVNC)
3) what are the values of the environment variables DISPLAY, VGL_CLIENT, and VGL_DISPLAY in your system
4) test whether "vglrun matlab" runs normally, and let me know the output of the command "opengl info" from Matlab right after it starts
Thanks
Alfonso
