MineRL could not detect an X Server, Monitor, or Virtual Monitor! #34

Closed ghost closed 5 years ago

ghost commented 5 years ago

Hello, I've followed the installation steps to get jdk 1.8, minerl (upgraded to 0.1.5), and installed xvfb. But i'm still getting the "MineRL could not detect an X Server, Monitor, or Virtual Monitor!" Error. I

I run the hello world program like so.

root@dd57e1fe29f8:/workspace/helloworld# xvfb-run python helloworld.py `

I get the following log output.

RuntimeError: ERROR! MineRL could not detect an X Server, Monitor, or Virtual Monitor! Currently minerl only supports environment rendering in headed environments (servers with monitors attached).

In order to run minerl environments without a head use a software renderer such as 'xvfb':
        xvfb-run python3 <your_script.py>
If you're receiving this error and there is a monitor attached, make sure your current displayvariable is set correctly:
         DISPLAY=:0 python3 <your_script.py>
If none of these steps work, please complain in the discord!

@MadcowD Hey, I found a way to make the script run. Basically, I installed both xorg and xvbf and then modified the xvfb-run command a bit. Here is the workflow that I had success with.

install xorg (needed for xvfb to work, for me) apt-get install xorg openbox

install xvfb for rendering in headless server apt-get install xvfb

the command below tests xvfb-run xvfb-run -s "-ac -screen 0 1280x1024x24" xvinfo

run python script with xvfb-run and some arguments xvfb-run -s "-ac -screen 0 1280x1024x24" python helloworld.py

This serves as a crutch for me. I don't understand why this works while the original command does not. At least I can move forward now.
