I have installed graphics driver on my droplet having Fedora 19, but if I open any application having GUI or access some graphics related libraries from my deployed application it gives an error "Gtk-WARNING **: cannot open display". X server is also not starting. It gives following error:
Fatal server error:
(EE) xf86OpenConsole: VT_ACTIVATE failed: No such device or address
Please consult the Fedora Project support
(EE) Please also check the log file at "/var/log/Xorg.0.log" for additional information.
(EE) Server terminated with error (1). Closing log file.
xinit: giving up
xinit: unable to connect to X server: Connection refused
xinit: server error
