Headless Ubuntu Server
Hi,

I'm trying to run the Esenthel server on an headless environment.

Code:
xvfb-run -a -e ./app.log ./Server

And i've this log

Code:
Xlib:  extension "XFree86-VidModeExtension" missing on display ":99".
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
Couldn't find valid GL Config
david@Cassiopee-Tux:~/Software/Esenthel$ Failed to connect to Mir: Failed to connect to server socket: Aucun fichier ou dossier de ce type
Unable to init server: Impossible de se connecter : Connexion refusée

(zenity:22576): Gtk-WARNING **: cannot open display: :99

Are there any other/better way to run the server without X ?

Hi,

The server requires OpenGL and X so it can display the user interface, including statistics, user list and permissions, project list.

Hi,

Thanks for the answer,

Does it also needs a GPU ? Or can it work (as the Windows version does) on the CPU ?

Hi,

On Windows you don't need a GPU because Windows has special software, that will handle rendering fully in CPU mode (it's called WARP - https://msdn.microsoft.com/en-us/library...s.85).aspx )
It's available only on DX10/11+

Other platforms don't have this feature.

It works fine with CPU only. Of course if you have X.

other platforms does have similar functionality through MESA or Swiftshader I believe, just for adding to this conversation. smile
