Alt+Tab on RDP Session from a windows client machine.

[Subbareddy Alamuru <su...@sycamoreinformatics.com>]

Hi Team,

Is there any fix for Alt+Tab functionality on RDP session when launched via
guacamole on a windows client machine?

In Mac it works but not in Windows.

Thanks
Subba

I'm assuming by full screen mode and keyboard lock, you're referring to
https://developer.chrome.com/docs/capabilities/web-apis/keyboard-lock.

For what it's worth, I just tested Chrome on Windows 10 and got their demo
to capture Alt+Tab successfully, so that seems good! Even Windows key
shortcuts like Win+D appeared to have been captured.

Short answer: No, Alt-Tab cannot be easily redirected to the remote session.

Long answer: There are situations where it can work, and some upcoming
changes that _might_ help it work, but no guarantees. The next version of
Guacamole, 1.6.0, will feature support for full screen mode and keyboard
lock, which might possibly help in some situations - however, it is
ultimately still up to the operating system of the client computer whether
to interpret the Alt-Tab key combination locally or pass that through to
the browser which can then pass it on to Guacamole. Unfortunately in the
case of Windows client machines, Windows is not very configurable in terms
of the key combinations like this, and is likely to interrupt and interpret
those key combinations locally and not pass them through, and, at the end
of the day, there isn't much that can be done about that. Mac is more
configurable with that regard, and Alt-Tab isn't a default shortcut in Mac,
and Linux clients are very configurable in terms of key combinations, so
this can be disabled on the client-side and passed through to the remote
systems.

You can try with 1.6.0 when that comes out and see if the full screen +
keyboard lock helps you with that.
