UPDATE: I have solved the issue I was facing. Since I am running the DeepMind in one of my instances of Google Cloud V's, via a VNC GUI server, the proceedings should work in any. I´ve opened the script file (run_cpu) and put the line "export QT_GRAPHICSSYSTEM=native" right before the line that runs qlua. Let me share you my editings:
(UBUNTU 12.* using latest vncserver + GNOME GUI) //terminal and where the dqn dir is:
$ vim run_cpu
//that opens the file 'run_cpu'. Press "i" to edit. The new edit should look like this (copy and paste at line 45):
export QT_GRAPHICSSYSTEM=native
//Press "ESC" then type ":wq" then enter.
$ reboot
//To make sure the effects will take change after restarting all processes. Open a new SSH terminal via Google Cloud console. Before running the vncserver, also run the export QT_GRAPHICSSYSTEM=native before:
$ export QT_GRAPHICSSYSTEM=native $ vncserver
Then, when connected thru a VNC client, open the terminal there and run ./run_cpu.
$ sudo bash ./run_cpu
//In case no root access.
UPDATE 2: I've also did a very small change at the dqn-graphics.sh. At line 4, leave nothing but the line with a 'then'. Like this ( :
//$ vim dqn-graphics.sh. Scroll at line 4. Press Enter. Put: then
//ESC :wq
