Summary: Keyboard translation broken: uses raw keycodes Product: Wine Version: CVS Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: major Priority: P2 Component: wine-x11driver AssignedTo: wine-bugs@winehq.com ReportedBy: peter@cendio.se
The X11 keyboard driver (dlls/x11drv/keyboard.c) uses raw X11 keycodes. This is wrong; keycodes are Xserver and hardware dependent. Applications should never use the keycodes.
One example when this is a problem is when using VNC, since Xvnc does not use the same keycodes as most XFree86 servers. This has led to that Wine has a special keymap for this special Xvnc server. But this keymap only supports the US keyboard layout. Basically, to support all layouts (x) on all servers (y), Wine needs to have x*y keymaps. This is just not feasible.
And even if it was, things would go wrong: Xvnc allocates keycodes dynamically, which is totally "legal". This means that "aring" can have different keycodes different times, depending on in which order the user has pressed international keys.
rdesktop (www.rdesktop.org) suffered from exactly the same problem. I have written a new keyboard translation implementation which uses Keysyms instead. Maybe Wine can re-use parts of this work.
