Hi Amyn,
Firstly, note that this thread is 3½ years old, Sebastien may not be around. ;-)
Second, I'm using my 2030 in Dvorak mode, but I got the same results in QW and 102. Also, I'm on Windows, so I can't verify what Linux will do.
I'm using AutoHotKey to see what the computer is seeing from the keyboard.
Third, I'm not quite sure what the "same problem" is.
The fn key ONLY works when it's the first key pressed and held down - it will always convert delete to insert or enter to volume down for example. If you want alt-delete, just press alt-delete (no fn).
When I press fn-alt-delete, I get alt-insert, never ctrl-alt-insert.
The only way I can get ctrl-alt-insert is by pressing fn-ctrl-alt-delete - and the delete key is converted accordingly. Note this is using the LEFT control and alt keys - the right ones get converted to Enter and Media_Next if fn is being held down.
If you need more info, please specify operating system, 2030 mode, and exactly what output you trying to achieve. ;-)
