Black screen on connect

Jorge Camara
Hello everyone.

I'm having constant trouble making connection using guacamole.
At some point, I make the connection to a server using RDP protocol.
In the first moment the screen turns black and the connection drops for 15 seconds.
Then a popup appears where I click on reconnect and the connection goes normally.

Below is the syslog log where you have the guacd log in DEBUG mode and then the log of my catalina.out.

Note: This issue is intermitent.

Anyone have any suggestions?

Looks like the file descriptor error is causing your problem. It sounds like, when your system tries to open the WebSocket session with the browser, the OS isn't creating the handler for it. Maybe the user has too many file descriptors open?

Can you give some more details about the system you're running this on?

Ok,

I´m using Ubuntu 16.04.1 LTS:  4.4.0-59-generic #80-Ubuntu SMP Fri Jan 6 17:47:47 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Even in successful connections this "file descriptor" error appears.

Where can I look at how many open files I have?

Are there any other errors in your catalina.out?

What about in the browser's JavaScript error console?

I have had this happen also, Black Screen until I used IE11.   Firefox didn’t work,  Chrome didn’t work.  IE11  never has an issue.

Re: Black screen on connect

With me it was the other way around. My experience of using guacamole in IE11 was worse. Black screen on almost all connections.

Output of my syslog:

Re: Black screen on connect

Jorge Camara
Hi. 
Actually I've reinstalled vm and it seems to work. 
Here in the company we suspended this project of guacamole use and since then we are not using it.
I also did not use any plugin as the redirection drive. Only session recording. 
Try to disable and run the tests.

All right. We'll try that.
Thanks!

Hi. 
Actually I've reinstalled vm and it seems to work. 
Here in the company we suspended this project of guacamole use and since then we are not using it.
I also did not use any plugin as the redirection drive. Only session recording. 
Try to disable and run the tests.

Hi Jorge,

Have you found any way around this issue?
We're facing it as well...

Thanks.

2017-01-26 17:19 GMT+01:00 Jorge Camara <[hidden email]>:
With me it was the other way around. My experience of using guacamole in IE11 was worse. Black screen on almost all connections.
