Hi list.
I often use X11 forwarding to run Linux programs with GUI.
Recently I upgraded from vbox 4 to version
VirtualBox-5.0-5.0.16_105871_el6-1.x86_64.
(My Linux host is headless Rhel 6.7 Server with xorg-x11-xauth package
installed)
I noticed that when I type "VirtualBox" in shell and then close its
window the process remains running. Then I noticed that there's another
hidden window in taskbar.
I have to press Ctrl-C or close the second window to end the process.
This only happens when I connect from Windows and use cygwin xwin server
(but not xming or Linux client)
The visible window is captioned "Oracle VM VirtualBox Manager@hostname"
and the hidden one is captioned "VirtualBox@hostname"
It's not really hidden. There's a white pixel at the top-left edge of my
second monitor
I upgraded my Cygwin installation today, but the problem did't go away.
Before the upgrade I had some messages appear in XWin.0.log, but now
they're gone:
[656077.648] winMultiWindowXMsgProcErrorHandler - ERROR: BadWindow
(invalid Window parameter)
[656077.664] winMultiWindowXMsgProcErrorHandler - ERROR: BadWindow
(invalid Window parameter)
[656077.664] winMultiWindowXMsgProcErrorHandler - ERROR: BadWindow
(invalid Window parameter)
I start the server from shell using an alias:
alias runx='run xwin -multiwindow -noprimary'
I have this at the end of my ~/.ssh/config:
Host *
ForwardX11Trusted yes
ForwardX11 yes
