Currently I am working on a remote server using Ubuntu yet the 'd' key cannot be used since it minimizes/maximizes all windows to show/hide desktop. Many answers point to the fact that I should go to the shortcuts and disable the "Hide all windows..." mapping.

EDIT:

I did disable other similar mapping such as 'Hide all normal windows' which is set to disabled ( I Cleared it with my backspace). Yet this has no effect. Or do I need to log off and on again?

My problem is that I do not have this shortcut mapping listed in the shortcuts settings!

I also cannot find the global_keybindings directory that many solutions suggest..

I tried to use the character map when I needed 'd' but when I was asked to authenticate an installation of a programm (and my password has a 'd'), and I pasted the character, authentication failed. I don't know whether this is another issue or not.

I don't have to access to log on or off, so I restarted the VM from my Azure, yet the same trouble was present.

Can you advice any work around?

@Oli - I tried using xev to check out the keyboard events

I tried to press a normal letter 'b'

KeyPress event, serial 35, synthetic NO, window 0x4000001,

    root 0x2e, subw 0x0, time 910899804, (358,-354), root:(359,184),

    state 0x0, keycode 56 (keysym 0x62, b), same_screen YES,

    XLookupString gives 1 bytes: (62) "b"

    XmbLookupString gives 1 bytes: (62) "b"

    XFilterEvent returns: False



KeyRelease event, serial 35, synthetic NO, window 0x4000001,

    root 0x2e, subw 0x0, time 910900467, (358,-354), root:(359,184),

    state 0x0, keycode 56 (keysym 0x62, b), same_screen YES,

    XLookupString gives 1 bytes: (62) "b"

    XFilterEvent returns: False

----then I pressed 'd':

FocusOut event, serial 35, synthetic NO, window 0x4000001, mode

On further investigation this does seems to be a widely noticed issue with XRDP. It's probably not the client sending rubbish along as I previously said in my comment, rather that it's the server doing weird stuff for an unknown reason.

Many people have documented that fixing this involves disabling the <Super>d binding for showing the desktop but this fix has had to evolve over the years as Ubuntu has upgraded components. There are a few basic options for doing the same thing:

Go into the shortcuts setting screen, find the shortcut and click it until it says disabled.

Nuke with Gconf (probably only works on older Ubuntu desktops) and log out and in again.

Manually edit the gconf XML (again, might only work on older desktops)

Install CCSM to get to the newer version of the settings.

Other people report other similar quirks with XRDP so if you're experiencing other issues (and/or you can't fix this one), it might be best to dump it and go with something else. There are a fair few to choose from but the main contenders are VNC (over SSH from Ubuntu, or over SSH from Windows with Putty) or FreeNX.

FreeNX is a lot less popular than VNC but it's a solid contender and a lot more like RDP than VNC (which can occasionally be a bit flabby if you're doing lots of graphics stuff). But VNC is easier to set up.
