[jira] [Commented] (GUACAMOLE-1028) Cut operation on RDP client
cause disconnect of session
[ https://issues.apache.org/jira/browse/GUACAMOLE-1028?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17084480#comment-17084480 ]

guacd[39724]: WARNING: Received clipboard data cannot be sent to the RDP server because the RDP server has requested a clipboard format which was not declared as available. This violates the specification for the CLIPRDR channel.

Assuming this is correct, this may well be why the connection is closed. This message shouldn't appear. If XRDP is ignoring the CLIPRDR spec, and is instead assuming the client will support the same clipboard formats as the Windows RDP client, it's conceivable that other assumptions might fail and the connection is killed.

> Project: Guacamole
> Issue Type: Bug
> Components: guacamole
> Affects Versions: 1.1.0
> Reporter: Jason Keltz
> Priority: Major
>
> I'm having trouble with "cut" operation under CentOS 7 and GNOME causing a disconnection of the RDP client. The same operation works fine on a Windows RDP host. Once the disconnection occured, I restart guacd like this:
> I start guacd -f -L debug then connect to a client...
> This is the output when the client reconnects and I try another cut:
