Black screen upon connect

Hi Jesper,

Could you generate the RDP logs of that session and send them to me. Here's how to do it: https://helpmac.remotedesktopmanager.com/howto_rdplogs.htm

Best regards,

I tried maybe 20-30 times with the log file enabled, but couldn't get it. Removed the log file, and BOOM! So something in the debug stuff is making the black screen not happening. Thoughts?

Well, this is definitely weird. Have you had this issue on other server than this specific Windows Server 2012 R2?

Oh! One other thing that could help us narrow down the issue. Could you try the same session after disabling OpenGL?

I want to see if the issue lies in the OpenGL rendering.

Best regards,

Only on Windows Server 2012 R2. I will try disabling OpenGL next time it happens.

No, it's the same when OpenGL is turned off.

OpenGL is not the culprit then. We'll have to investigate this further.

I'll post back on this thread when we make any progress or if we need more information.

Thank you for your help.

Best regards,

Hi Jesper,

I've been briefly able to reproduce this, but only with the Engine V4 and pretty inconsistently. Could you export one of the sessions (remove any sensitive information e.g. passwords, host names, etc.) and send it to me via private message. I'd like to see if a specific configurations exacerbate the problem.

Could you also check if this is any better with the sandboxing turned off?

Best regards,

No problems, my creds are inheriting from a group/folder anyway, so no passwords are stored in my RDP profiles. You'll have it in a couple of minutes.

Xavier, I found another clue to the Black Screen. With v5.1.0.0 and later, it ONLY happens in Legacy mode.

When I'm in Legacy mode, some times (a lot of times,) it opens a new session with the SAME SCREEN as the session I was previously connected to/just disconnected from. If I haven't connected before, then it's black. It seems like the previous screen buffer has not been purged or something.

Hi Jesper,

Just one more details before I delve into this. Was turning Sandboxing off changing anything?

Best regards,

No, Sandboxing on/off does change anything.
