Some german keys: "?" and "ß" mismatched #108

Closed totaam closed 11 years ago

totaam commented 12 years ago

Issue migrated from trac ticket # 108

component: client | priority: critical | resolution: worksforme

2012-04-13 14:15:24: stephan created the issue

What steps will reproduce the problem?

  1. Start xev in xpra
  2. Press the "ß" key (right to "0") on a German keyboard, with and without Shift
  3. Do the same without xpra

What is the expected output?

What version of the product are you using? On what operating system?

xpra v0.1.0, (K)ubuntu 11.10

Please provide any additional information below.

So the problem is that xpra transalates the question mark into an upside down question mark, and the sharps into a backslash. The backslash is on that key, but only with ISO_Level_3_Shift (Right Alt, AltGr).

Please provide the output of:

  • setxkbmap -print
  • setxkbmap -query
  • xmodmap -pm
  • xmodmap -pke And an exact diagram of the keyboard layout in question would be really helpful too for testing. (wikipedia seems to have many, is it this one?)

related bugs: see also #109 (and maybe even #86)

Just saw that in my xev listings, one difference is also that the state variable seems to have 0x6000 ORed in, always. Maybe that is confusing the modifier logic?

totaam commented 12 years ago

2012-04-16 19:17:38: antoine commented

Is the output above from the local machine or from within xpra? (both should be almost identical)

As for the 0x6000 ORed in, that is a possibility - I just don't know what this state is! (will need to dig it up from the xev sources)

I don't know what 0x6000 is. I don't get it in my case:

The diff between the two looks fairly significant... there seems to be some mixup how the two active layouts (de,us) are mixed into the keycodes. The native version seems to go <de> <de_shift> <us> <us_shift> <de_R_alt>... while the xpra version does <us> <us_shift> <us> <us_shift> ... ... <de> <de_shift>. That is consistent with the question mark key (keycode 20):

Native:

keycode  20 = ssharp question minus underscore backslash questiondown U1E9E

Xpra:

keycode  20 = ssharp question backslash questiondown U1E9E minus underscore

Making it obvious that the things are actually there, but apparently the fourth entry is used instead of the second, hinting at some US / DE mixup?

Hah, sorry about that.

You need to run this with python2, and have the whole of trunk installed. OR, just revert the gtk3 crap, by replacing:

    from wimpiggy.gobject_compat import import_gdk
    gdk = import_gdk()
    try:
        keymap = gdk.keymap_get_default()
    except:
        keymap = None
        return  []

with:

    import pygtk
    pygtk.require("2.0")
    import gtk
    keymap = gtk.gdk.keymap_get_default()

And name = gdk.keyval_name(keyval) with gtk.gdk.keyval_name(keyval).

Or even, easier is to just add this to the version you have from the release:

def main():
    gtk_keymap = get_gtk_keymap()
    print("gtk_keymap: (keyval, name, keycode, group, level)\n%s" % ("\n".join([str(x) for x in gtk_keymap])))

if __name__ == "__main__":
    main()

Hi, this definitly helps with most keys. Thank you! The only remaining issue that I perceived was with right Alt (ISO_Level_3 shift) + "ß" (right of top row "0") which should produce a "\", but continues to produce a "ß".

The other R_Alt combinations work, for example R_Alt + 0 = }

In trying to reproduce your problem I found this interesting error message:

Warning:          Type "ONE_LEVEL" has 1 levels, but <RALT> has 2 symbols
                  Ignoring extra symbols

Which led me to some bug reports:

More info found on the xkb_symbols like this one:

xkb_symbols   { include "pc(pc105)+fi+inet(logicdp)"    };

"All the xkb_(whatevers) in the setxkbmap output are directories inside /usr/share/X11/xkb, and the (optionally plus-delimited) include parameters are files inside those directories. The stuff inside parentheses are sections inside those files. lessing about said files is a good way to see what sort of stuff gets fed to xkbcomp."

Also doc on Defining New Layouts and XKB-Config, and extending-xkb

One very useful command for visualizing the keyboard map:

xkbprint -label name $DISPLAY - | gv -orientation=seascape -

The problem is that when I setup my keyboard like yours... I don't have the problem (yet).

As for the Xev data, correct me if I am wrong, but the only noticable difference that I can see for the "ß" key are: keysym 0x5c, backslash (x11) vs keysym 0x1001e9e, U1E9E (xpra) There are no differences for the ISO_Level3_Shift keypress/keyrelease.

Can you apply this small patch and tell me what the server prints when you hit this key combination on the client:

Also, r942 caused some regressions in win32/osx clients, so r1121 re-instates the "preserve keycode" functions for clients without proper keymap definitions (osx, win32, ..)

totaam commented 11 years ago

2012-10-03 07:53:30: antoine commented

I have just committed a large amount of code to try to properly fix support for "ISO_Level3_shift" (see r1779 and the previous few days in timeline), including fixes for win32 clients.

It seems to work here (though I never use "AltGr" myself so I cannot be certain all keys do map correctly), however, in the process I have found that the core X11 APIs are not symmetrical, which means that the layouts we set are not the layouts we get back.. meaning that it is impossible to ensure that the layouts match exactly without using the Xkb API (which is a sizable amount of work).

Hopefully, this change will be enough to fix your remaining issue - if not, it will have to wait a little while longer.. sorry. You can find beta packages with those changes in the beta area
