I have done that and piped the output to a logfile. Attached is an abbreviated
version with just the icelandic and turkish detection included. It seems to
be mismatching on detecting the third keysym where the key is defined
in /etc/X11/xkb/symbols/tr this could be a clue :)

I took another look at the code and with the trace I have to say that I was
The trace only shows 0x0000 for the third(?) keysymb so I dont know what was
returned. I believe (gingerly) that is due to the trace having a precision of
TRACE_(key)("mismatch for keysym 0x%04lX, keycode %d,
in function X11DRV_KEYBOARD_DetectLayout where it should be
TRACE_(key)("mismatch for keysym 0x%08lX, keycode %d,
or my version of X11 is returning a larger value than it should. I suspect
this because of the large amount of calls to the function
KEYBOARD_MapDeadKeysym. Maybe the X11 guys have changed a short to a long
somewhere in my version of X11 (cvs 2003-11-24) or my gcc (3.2.2) has defined
them differently. If that is the case then the line
ckey[i] = keysym & 0xFF;
in function X11DRV_KEYBOARD_DetectLayout would change the keysym and cause a
mismatch. Another thought popped up is maybe the X11 guys extended the
keysymb codes to allow for 6 instead of four combinations. I will have to
check the changelogs to be sure.
