OpenBCI GUI does not start, blank screen [resolved]

Hi all,
I have downloaded the latest version of openBCI GUI. I am running the executable as an administrator. The window of GUI pops up but remains blank forever. I am using windows 10. Has anyone faced such issue and resolved it?

    Aditya, hi.

    In the past, when users of the GUI see a blank screen, it has been the case that their graphics card / chip drivers need updating. The GUI uses Processing language which depends on up to date OpenGL drivers. Try visiting your manufacturer's support website and see if you have the latest drivers.

    The other suggestion is to run the GUI from the Processing IDE, described here,

    Mystery, are you saying that it works standalone, but fails from the Processing IDE?

    Have you checked that your OpenGL drivers are up to date?

    I solved the problem several times by rebooting the board and the computer

    Hi wjcroft,

    All the graphic drivers and openGL are up to date in my system. The problem still persists. I am trying to use processing to open the software but i get an error while opening processing. The link to the screen shot of error is added below.


    Thanks

    Can you mention the computer you are using and approximate date of it's manufacture? I do know that as time passes, manufacturer support of drivers and older hardware fall behind. Was this computer previously running Windows 7, and you upgraded? Are you certain that your model of computer is fully supported for Windows 10?

    "...but i get an error while opening processing. The link to the screen shot of error is added below."

    Are you saying that the Processing IDE itself, will not start?

    wjcroft,

    The computer I am using is HP 15-ac119TX. It comes with windows 10 installed from manufacturer. Year of manufacture is 2016.

    Yes the processing IDE itself did not start.

    But I downloaded a fresh copy of Processing IDE and it worked. 

    Later OpenBCI_GUI-master was downloaded from GIT repository and extracted to the location specified in learning section of OpenBCI GUI. When i tried to open the BCI sketch, there was conflict in libraries of LSLink and jna. I moved the LSLink folder in libraries to some other location to avoid the conflict. When I restarted the processing IDE and tried to run OpenBCI sketch, It worked.
     I am able to see the GUI working now. Still not sure of the problems that may occur due to the removal of LSLink library.

    I shall update if any issues found further.

    I know about the conflict that can happen with LSLLink and jna. Adding jna fixes the LSL in standalone.

    So, I just reproduced the error. To fix the duplicate library, remove the "jna" package from C:\Users\Username\Documents\Processing\libraries .

    Then, restart the Processing IDE to re-load the libraries.

    You still need the jna package in the local Git repository if you want to build the GUI yourself (Processing App->File->Export Application).

    Updating the Docs to explain this.

    After recently upgrading my computer I had similar problems with the GUI failing to launch and showing a blank screen, even with up to date Open GL and graphics card drivers. However, I was able to solve this by changing my Nvidia driver from a Game Ready Driver (which is optimized for new game launches) to a Studio Driver (which is optimized for stability). You can choose this on the Nvidia Download Drivers page by selecting it in the dropdown menu labeled "Download Type"

    Quick edit: I should mention I'm on Windows 10
