if i launch konsole , gnome says :
Cannot open /dev/ttyS0 : Permission denied
If i try to connect to this host through ssh the command gets stuck after it asked the key's password.
In the 'real shell' if i use completion tab on any command it says of a /dev/fd/0 as sayd above .
It is rally strange , whatever terminal , or form of console bash having to do with devices like /dev/pty .
Konsole is unable to open a PTY (pseudo teletype). It is likely that this is due to an incorrect configuration of the PTY devices. Konsole needs to have read/write access to the PTY devices.
That's all i can say i will try to post more debugging output next posts
