Using the Canadian Multilingual Standard keyboard with Windows XP

Using the Canadian Multilingual Standard keyboard with Windows XP

[Young, George]

Using Windows XP and cygwin started with the command
%RUN% XWin -multiwindow -clipboard -silent-dup-error -xkblayout ca
-xkbvariant multix -xkbmodel pc104

If the Windows keyboard is set to US, cygwin works fine. If the Windows
keyboard is set to Canadian Multilingual Standard, cygwin doesn't get
the RightAlt and RightControl inputs.

Regards,
George R. Young

I couldn't reproduce this.  Checking with xev, the right alt and right control 
keys generate key events when the Windows keyboard layout is Canadian 
Multilingual Standard, although it seems that right control generates the same 
X keysym as left control with that layout for some reason.

Can you clarify how you are checking for the keypresses?

Thanks.  This helps a lot in understanding the problem.

There seem to be two things going on here:

1) In the Canadian Multilingual Standard layout, Ctrl-R is VK_OEM_8 (rather 
than the more normal VK_CONTROL) which isn't in the mapping table to ignore 
the VK code and use the scan code.

2) Windows generates an additional Ctrl-L key event before AltGr key event for 
international keyboard layouts.  There is code in the X server to try to 
identify and discard these extra events, but this doesn't seem to be working 
in your case (and there have been other reports of that)


I don't see why we can't just always load the US keyboard layout as all we 
care about are scan codes:  Patch to follow which adds a flag to do that and 
turn it on for Japanese (which already does that) and Canadian Multilingual 
Standard.

I've also added a keycode mapping for VK_OEM_8 in case that ever fails, and 
improved some logging related to the keyboard layout detection.

I've also added the multix layout to the list of autodetected layouts.


I've uploaded a build with this patch applied [1]. This seems to correctly 
generate ISO_Level3_Shift for AltGr and ISO_Level5_Shift for Ctrl-R in the 
multix layout. Perhaps you could try it out and see if it works for you?

Although I am still a bit unclear as to what exactly doesn't work for you. 
Originally you said "If the Windows keyboard is set to Canadian Multilingual 
Standard, cygwin doesn't get the RightAlt and RightControl inputs", whereas 
this xev output seems to demonstrate that the X server gets events, just not 
the right ones :-)

[PATCH] Fixes for Canadian Multilingual Standard keyboard layout handling

[Jon TURNEY]

Try to make the keyboard detection logging a bit clearer

I don't see why we don't just always load the US keyboard layout as all we
care about are scan codes:  So add a flag to do that and turn it on for
Japanese (which already does that) and new layouts...

Add a keycode mapping for VK_OEM_8 which can be issued by Canadian Multilingual
Standard layout

Reformat the keyboard layout mapping table

Clarify XKB options in XWin man page

RE: Using the Canadian Multilingual Standard keyboard with WindowsXP

[Young, George]

Hello Jon,

I tried the patch and am very impressed. My WinXP was set up with English-Canada and 2 keyboards, Canadian Multilingual Standard and US. When I ran the cygwin patch, it added English-US with a US Keyboard, and switched to that.

In cygwin, the RightAlt and RightControl do what they're supposed to do (almost). There still seems to be a small problem with dead key stuff. 

When I first run the cygwin server, and press the keys for dead-cedilla (RtCtrl and =) then c, it just gives c. If I then run xev and stop it, the dead keys start to work and it gives ç.

Good stuff,
George R. Young

Thanks.  This helps a lot in understanding the problem.

There seem to be two things going on here:

1) In the Canadian Multilingual Standard layout, Ctrl-R is VK_OEM_8 (rather than the more normal VK_CONTROL) which isn't in the mapping table to ignore the VK code and use the scan code.

2) Windows generates an additional Ctrl-L key event before AltGr key event for international keyboard layouts.  There is code in the X server to try to identify and discard these extra events, but this doesn't seem to be working in your case (and there have been other reports of that)


I don't see why we can't just always load the US keyboard layout as all we care about are scan codes:  Patch to follow which adds a flag to do that and turn it on for Japanese (which already does that) and Canadian Multilingual Standard.

I've also added a keycode mapping for VK_OEM_8 in case that ever fails, and improved some logging related to the keyboard layout detection.

I've also added the multix layout to the list of autodetected layouts.


I've uploaded a build with this patch applied [1]. This seems to correctly generate ISO_Level3_Shift for AltGr and ISO_Level5_Shift for Ctrl-R in the multix layout. Perhaps you could try it out and see if it works for you?

Although I am still a bit unclear as to what exactly doesn't work for you. 
Originally you said "If the Windows keyboard is set to Canadian Multilingual Standard, cygwin doesn't get the RightAlt and RightControl inputs", whereas this xev output seems to demonstrate that the X server gets events, just not the right ones :-)

Thanks for trying it out.

Hmm... this is a rather unfortunate side-effect of loading the US keyboard 
layout, and there doesn't seem to be a good way of preventing it appearing in 
the language bar.

I think maybe I should try the alternate approach of handling VK_OEM_8 
correctly and trying to work out why the code to discard the spurious Ctrl-L 
key events isn't always working (it works fine for me)

I've uploaded another build at [1] which tries that, with lots of extra 
debugging built in.  I wonder if you could check if Ctrl-R deadkeys work 
correctly with that, and also if you could provide me with the output of 'tail 
-f /var/log/XWin.0.log' and xev from pressing AltGr.

I'm afraid I can't reproduce this, I always get a ç, but I may not be doing 
the right thing.  Can you give me some more detailed steps about how you are 
starting the Xserver, and the application you are typing into?

For the dead-cedilla problem, the server is started with 

%RUN% XWin -multiwindow -clipboard -silent-dup-error -xkblayout ca -xkbvariant multix -xkbmodel pc104
%RUN% xterm +tb -e /usr/bin/bash -l

and I'm just typing in the xterm window. Immediately afer starting the server, RtCtrl = c gives c. After running some other application (e.g. xev, xterm +tb), it starts giving ç. And sometimes just to tease, it gives ç immediately upon startup.

In any event, this patch seems to work as well as the last one, and it doesn't visibly impact the WinXP language selector thingie.

So again, good stuff.
Regards,
George.

Thanks for trying it out.

Hmm... this is a rather unfortunate side-effect of loading the US keyboard layout, and there doesn't seem to be a good way of preventing it appearing in the language bar.

I think maybe I should try the alternate approach of handling VK_OEM_8 correctly and trying to work out why the code to discard the spurious Ctrl-L key events isn't always working (it works fine for me)

I've uploaded another build at [1] which tries that, with lots of extra debugging built in.  I wonder if you could check if Ctrl-R deadkeys work correctly with that, and also if you could provide me with the output of 'tail -f /var/log/XWin.0.log' and xev from pressing AltGr.

I'm afraid I can't reproduce this, I always get a ç, but I may not be doing the right thing.  Can you give me some more detailed steps about how you are starting the Xserver, and the application you are typing into?
