Description Martin Capitanio 2008-05-29 07:33:43 UTC
* Two keys ( < ^ ) were incorrectly swapped for no apparent reason.
* The F-keys stopped working to a usable level expected by a normal Linux user.
  Modify default FN key behavior on Apple keyboards.

Adding Diego to CC, as this has been caused by his patch.
Comment 5 Diego Elio Pettenò 2008-05-29 08:26:37 UTC
The Fx key behaviour is something that I think comes up over and over. In the mail thread started by Dag Bakke, which I was CCed on by Andrew Morton, Matthew Garret replied:

As for the swap, that's something that bothers me, but I didn't really "cause" it, it already was there on 2.6.25 before my patch. It's the usual behaviour of the Apple ISO keyboards. By the naming of < and ^ I suppose it's not an US keyboard, I'd suppose German?

I'm not sure why Apple does it this way but it is true that the _US_ variant of the Apple ISO keyboards have the `~ key in the bottom left corner rather than in the upper left corner. Maybe this should become its own quirk with its own switch to enable/disable it? I can work on that, sincerely I dislike that choice too and have X remapped to put them back.

Then somebody should tell Linus, that Andrew & co. are horribly wrong. Imagine Linus' daughter is sticking this Keyboard in any machine with recent kernel and it breaks his hands.

Not mentioning Alice, the frame buffer hacker.
It may be hard to convince this guy to fix his firmware
http://www.lulehome.de/blog/media/mac_tastatur2.jpg

so it will be great if we can somehow apply this quirk only to the us
keyboard.
Thanks Martin
Comment 8 Diego Elio Pettenò 2008-05-29 11:09:06 UTC
Yep I see your point, the German layout is fine, just like the Italian one.

I doubt it's possible to get the keyboard to let us know which layout it has, I don't think I have ever seen OSX doing that either (although it seems to know what the laptop layout is). That particular quirk could be moved from the kernel to the userspace though, I suppose, with either kbd or x11 doing the remap upon user request.

Changing this might be a bit of an abrupt change, but making it optional now, making it default off in a further release, and then removing the option even further on, giving time to userspace to deal with the issue, could be a nice way to resolve the issue... I actually was thinking about that after I fixed the numlock issue, but then I thought it would probably have been just me.

As for the Fx mode, it can be changed either as a module or kernel parameter or through a change to /sys/module/hid/parameters/pb_fnmode, so I wouldn't be that dramatic ;)

Are the us and the other layout HID descriptors exactly the same?

Well, maybe she is more clever than the daddy and knows some universal root exploit ;)

BTW, I just don't grasp the reasoning here.

Completely wrong. Show me somebody running linux kernel, expecting 
his keyboard to behave like under MacOS. On the contrary. All alu-keyboard users I know, are thinking the kernel dewelopers must be mad.
Comment 12 Martin Capitanio 2008-05-29 22:49:01 UTC
There is a endless count of bug reports/fixes like this one:

"Belgian Keyboard
As Belgian Mac's keyboard has never been correctly adapted, changes are bigger than the swapping keycodes as the canadian multitouch, we have to redefine @, #,€,`,[,],{,}. On Mac OS, to have {}, we use the CMD button with '(' and ')' , and for [ ], we use CMD + SHIFT + '(' and ')'. On linux, I've mapped it identically, but with ALT (left). So to write '{' we use ALT +'(' and for '[' we use ALT+SHIFT+'('."

Maybe the kernel should load keyboard quirks via firmware mechanism or give the user space more sophisticated interface. Logically, I think, this all must be fixed inside the kernel (not in X11, not in console, not in frame buffer, ...) the question is _how_? Prove me wrong.

Could somebody post lsusb -vvv from the us keyboard?

Do it! :-)
Found a hardware fix for all the us layout users:

Comment 14 Diego Elio Pettenò 2008-05-30 05:22:44 UTC
I sincerely think that it's userland's task to actually change the behaviour of the keys, rather than the kernel's. For once, if the quirk would be handled by X11, any system that supported X11 could have the quirk available at once.

That said, I'm not much of an HID hacker so I'd rather hear something from Jiri at this point...
Comment 15 Martin Capitanio 2008-05-30 14:48:15 UTC
... but don't frighten thinking further ;)
What about to kill all that Funny Keys as default and let the userspace tell the kernel to attach a FSM + key or string table to any key they want. And you must be not on X11 crack to get your keyboard working.

What about the ps2, infrared, bluetooth, ... everybody is playing a quirk games in his sandbox. 

Yes, I have the bluetooth alu twin sister here. Trust me, it's just the same nightmare.

I have the same problem and I also think that this is a device detection issue, hence a kernel thing.
I had to do some hunting that I was able to map the keys almost the way I wanted *but* the Print Screen key.

Kernel: 2.6.27-9-generic #1 SMP Thu Nov 20 22:15:32 UTC 2008 x86_64 GNU/Linux

Kernel: 2.6.27-9-generic #1 SMP Thu Nov 20 22:15:32 UTC 2008 x86_64 GNU/Linux

I have mapped F14 to Print screen and after trying xev this is what I get when I press the F14:

KeyRelease event, serial 34, synthetic NO, window 0x3400001,
root 0x13b, subw 0x0, time 1661372, (-1801,207), root348,1599),
state 0x12, keycode 192 (keysym 0xff61, Print), same_screen YES,
XKeysymToKeycode returns keycode: 107
XLookupString gives 0 bytes:
XFilterEvent returns: False

On the other hand this is what happens if I press the Print Screen on another keyboard (that works as it should):

Comment 19 Dave North 2009-02-12 15:17:09 UTC
Don't know if this is the right place to bring this up, but if it isn't perhaps someone can point me to a better spot ... as of 2.6.28 the function keys on my Annoying Aluminum Keyboard stopped working (makes shifting consoles a challenge). No problems through 2.6.27.9, then dead. XEV for F1 on 2.27.9 is a normal:

KeyPress event, serial 29, synthetic NO, window 0x1000001,
    root 0x5d, subw 0x0, time 6638389, (909,-188), root:(1035,36),
    state 0x10, keycode 67 (keysym 0xffbe, F1), same_screen YES,
    XLookupString gives 0 bytes: 
    XmbLookupString gives 0 bytes: 
    XFilterEvent returns: False

... but on 2.6.28[1-4] I get:

KeyPress event, serial 32, synthetic NO, window 0x600001,
    root 0x5d, subw 0x0, time 44288, (-276,81), root:(840,525),
    state 0x1c, keycode 101 (keysym 0x0, NoSymbol), same_screen YES,
    XLookupString gives 0 bytes: 
    XmbLookupString gives 0 bytes: 
    XFilterEvent returns: False

Failure also happens in the root console (no X). An older Mac keyboard works fine, also a typical 104Key USB keyboard works fine -- the problem is confined to my aluminum keyboard.

I tried fussing with the HID Devices and/or Special HID drivers and editing .config to see what happens if CONFIG_HID_APPLE=y is turned off, but I couldn't manage it! (Even editing .config doesn't work. Some script is outsmarting me).

I'm using Ubuntu 8.4 with my own kernel; here's the ver_linux output:

fix apple alu keyboard (>=.29)

To celebrate the bugs anniversary I just post here for interested parties
my patch updated for >=.29 kernels. It makes both (usb and wireless)
german apple alu keyboards usable again. Tested up to 30-rc5,
enjoy mc.
Comment 21 Yves-Alexis Perez 2010-11-24 11:30:40 UTC
it seems a fix (54a6593d65e638ad7e1e8cc986159d76054dab4b) was committed to master to fix this bug, enabling people to enable/disable the ISO_LAYOUT using a module parameter.

But it seems that this fix doesn't really work. On my powerbook G4 5,6 (alubook), changing the parameter doesn't change anything: keyboard works fine on console, not in X if I don't set the apple:badmap option (which needs to revert a patch in xkeyboard-config).

I don't see any issues on Fedora 14 or Ubuntu 10.10.

echo 2 /sys/module/hid_apple/parameters/fnmode
echo 0 /sys/module/hid_apple/parameters/iso_layout
works as intended and makes the keyboard usable.

So this issue should by actually marked as FIXED.
