Charles Rolls created GUACAMOLE-449:
---------------------------------------
Summary: ALT key not working with Windows Server 2012 R2 Standard
Key: GUACAMOLE-449
URL: https://issues.apache.org/jira/browse/GUACAMOLE-449
Project: Guacamole
Issue Type: Bug
Affects Versions: 0.9.13-incubating
Reporter: Charles Rolls
Priority: Blocker
Using VNC protocol (pvnc, tightvnc) on device running Win2012 R2 with a reverse
connect back to GuacD running in docker container on CentOS and client in IE 11
or Chrome 62.0.3202.94 running on Win7, when I hit the ALT key nothing happens
on the device.
I am using web sockets in the browser to connect to a Java Guacamole servlet
utilizing the Guacamole library in a Spring Boot app (Wildfly) to connect to
GuacD. I have run this servlet on Windows and CentOs docker container with the
same issue.
Thru the browser client, I'm in Notepad on the device and I hit the keyboard
L/R ALT key to bring focus to the menu. I see the guacamole protocol "keys"
instruction get sent over the web socket but nothing happens on the device. I
originally found this problem by adding a button to my HTML page to call
Guacamole JS client sendKeyEvent method to send the key combinations (L_ALT
pressed, TAB pressed, TAB unpressed, L_ALT unpressed). I have a button for
Windows key and CTL+ALT+DEL also. The Windows key works and the funny thing is
the CTL+ALT+DEL works sometimes but ALT+TAB never works.
Everything works fine with device running Win7 or Win10. It is only a problem
with WinSrv2012. I tried all combinations of the sendKeyEvent method with
things like delay between key press / unpress. That is what lead me to just
seeing what the keyboard ALT would do instead of clicking a button to do the
sendKeyEvents.
