Hello,
having recently replaced my old keyboard (that had a US layout) with an
italian one, I'm having a problem with Cygwin X when running HP-UX
clients: AltGr does not work and this prevents me to use characters like
[ { } ], etc.
I'm up to date with Cygwin and Cygwin X at the moment (1.7.9(0.237/5/3)
2011-03-29 10:10 i686 Cygwin for Cygwin and 1.10.2.0 for XWin).
These are the steps to reproduce the problem:
1) start Cygwin X
2) disable access control (xhost +)
3) access via telnet/ssh a HP-UX machine
4) open an xterm from the HP-UX machine in Cygwin X
5) in the newly opened xterm try to use AltGr (AltGr + è (i.e. the
key at the right of P), should produce {, while AltGr + Shift + è
should produce {)
6) fall on the floor crying in desperation
Notice that when using a client from a Linux machine all works properly.
A googled a lot and found a lot of information but only few of it
applied (=helped) to my specific case. I tried to mess with xmodmap and
kbd config files and also with other stuff, but nothing seemed to solve
the problem.
At the moment I'm using Xming 6.9.0.31 that doesn't seem affected by the
problem IF I set XKB_DISABLE=1 on the client machine (i.e. HP-UX).
Trying to troubleshoot the problem, I used xev on the HP-UX machine to
see if the keys were properly recognized and, in effect, they are.
This are xev results for Cygwin X, when I press (and release) AltGr+è
(thus by trying to get [) with XKB_DISABLED not set:
