I am running Lubuntu 18.10. Blender starts normally when I am on the desktop, but when I try to start Blender thru XRDP nothing happens.

When I try to start Blender thru the terminal using sudo blender, I get the following error:

Read prefs: /home/me/.config/blender/2.79/config/userpref.blend
/build/blender-UBljLx/blender-2.79.b+dfsg0/intern/ghost/intern/GHOST_WindowX11.cpp:198: X11 glXQueryVersion() failed, verify working openGL system!
initial window could not find the GLX extension
Writing: /tmp/blender.crash.txt
Segmentation fault

Please note that from time to time Blender used to start normally without any problems thru XRDP. How can I fix this?
