My virtual machine runs xrdp and when I connect with rdesktop, the "windows" key (i.e. Super_L) is not assigned properly.
Using xev I see that when the windows key is pressed, instead of showing Super_L, it shows Control_L. The real CTRL key also shows Control_L.
In other words, both the windows key and CTRL have the same effect.
How can I fix this, so that the Windows key maps to Super_L, same as on my laptop?
