Windows remote desktop: Black Screen

[Ankit.Jain]

Hi,

I am currently getting a black screen when I try to launch my app after connecting to a remote desktop via Windows Remote Desktop.

I found that if I launch the same app at the remote desktop itself before connecting via WRD, the app shows a proper output.

May I be suggested how I can work around this problem??

Thanks
Ankit

P.S The app also uses openGL. Though the same exists inside a Qt widget.

Hi
Unless your RDP server is very, very new, openGL do not work unless app is started BEFORE you remote control the pc.

Most solutions uses a script to disconnect RDP and start app.

@mrjj
I tried tscon 1 /dest:console before running the exe, but I started getting the error 7045.
I tried adding the password parameter and passing the function via runas, but both failed.

I'm not sure, but will disconnecting RDP before startup actually disconnect the remote connection??

Edit:
Reading other comments, it actually will disconnect my remote connection. Isn't there a better way to do this?

Hi
The RDP id might no be 1 always.
tscon 1 /dest:console
i think that is what error is

  Before startup ? what startup? of the app ?

I often just use teamviewer to open pc, start app and then connect with
RDP :)
