[Qemu-devel] [PATCH] fix '/' and '|' on russian keymap

[Qemu-devel] [PATCH] fix '/' and '|' on russian keymap

[Eduardo Habkost]

Patch from Oleg L. Sadov.

Removes broken 'slash' and 'bar' definitions (that were duplicated) from
the 'ru' keymap.

I can't test it myself, but the the fix was reported to be working, at:
https://bugzilla.redhat.com/show_bug.cgi?id=580637

Testing of russian keymap (was Re: [Qemu-devel] [PATCH] fix '/' and '|' on russian keymap)

[Eduardo Habkost]

Anybody using a russian keyboard layout who can test this change and
confirm it works as expected?

There's no need to rebuild qemu to test it. Just changing the keymap
file on /us/share/qemu to remove the last two lines (shown below) should
be enough.

I can perform such a testing - in theory.  But in practice, I was never
able to figure out this -k $lang stuff, -- neither in qemu nor in other
apps like rdesktop and the like.

What I usually do is to explicitly set en-us keyboard for applications
that are "too smart" and tries to guess "right" keyboard from env.
variables such as $LANG.

The reason is that after specifying "ru" keyboard, I can't use latin
chars anymore, and can type only using cyrillic.  Since cyrillic
layout does not have any latin char, imagine how to type, say, a
path name (even "C:" drive in windows).

All modern OSes nowadays have a way to switch between keyboard layouts
dynamically - this is done internally in the operating system.  So,
basically, I've no idea what this -k $foo stuff is used for to start
with ;)

Care to explain please?  Oleg?  :)

Thanks!

Um, regardless of my previous email, the change is indeed correct and
needed, or else the slash/question key (the one that's usually on the
left from the right shift, above the windows key) produces backslash
and vertical bar instead.  So I can confirm it's the right change.

(But I still don't know what's the reason of all these keymaps ;)

Sorry for delay with answer -- vacations time without e-mail account
access.

I don't understand reasons for such locale-default keyboard settings for
qemu too, but may be it's useful for someone...

-k only exists to deal with crappy VNC clients.

If you use a good VNC client (like vinagre or virt-viewer) then you 
don't have to use -k.

Indeed you must *NOT* use -k then, because that disables the extension
that vinagre/virt-viewer rely on for sane keyboard handling.

I don't use '-k' option directly -- in my RHEL-based system it's
automagically appended to qemu-kvm by libvirt. KVM XML-description,
created by standard virt-manager GUI-interface (package
virt-manager-0.6.1-12.el5.x86_64), has a 'keymap' attribute of
'graphics' tag, despite that configurator don't have any controls for
'keymap' setting.

As I understand, 'default_keymap' function from util.py (package
python-virtinst-0.400.3-9.el5.noarch) got information
from /etc/sysconfig/keyboard, then keymap searched in 'keytable'
dictionary from keytable.py and automatically placed to 'keymap'
attribute of 'graphics' tag in virtual-machine XML-description.

In our system we have a russian keyboard settings => we've got a XML
description like this:

 <graphics type='vnc' port='-1' autoport='yes' keymap='ru'/>

and, as a consequence, qemu-kvm running with '-k ru' option.
