Keyboard problem with 2.6 kernel

Message

Hello,

Some people may want to have me killed for that, but for the past months I've been using a MS Wireless Desktop (Keyboard + Mouse):

Code: Select all

input0: USB HID v1.11 Keyboard [Microsoft Microsoft Wireless Optical Desktopï¿½ 1.00] on usb1:5.0
input1: USB HID v1.11 Mouse [Microsoft Microsoft Wireless Optical Desktopï¿½ 1.00] on usb1:5.1

Anyway, both the keyboard and the mouse work perfectly with gentoo-sources, although I do get keycode errors which I just ignore:

Code: Select all

keyboard.c: can't emulate rawmode for keycode 272
keyboard.c: can't emulate rawmode for keycode 273

I was trying to keep away from the dev-kernel series because of 'exotic' hardware like this, but you know how tempting it is

So, I gave a shot to mm-sources-2.6.0-test10 last night. Everything worked fine, except for the keyboard. I don't get the keycode errors anymore, but instead it prints exclamation points (!) to infinity, as if I was holding shift+1. I'm pretty sure it's the keyboard, since unplugging it will stop the !.

Anyone have any ideas about what I could do to make this work?

Maybe just blocking the erroneous keycodes...?

The keyboard driver in 2.6 just seems to have been generally b0rked.

I always had 2.4 working fine with all the keys on my laptop but with 2,6 it claims the (i) button (next to power button) on my Dell laptop is a:

Code: Select all

atkbd.c: Unknown key released (translated set 2, code 0x7a on isa0060/serio0).
atkbd.c: Unknown key released (translated set 2, code 0x7a on isa0060/serio0).

The volume keys still work though. Its annoying because I used the (i) to bring up a new terminal.

mm-sources applies some 2.4 compatibilty patch but this makes no difference for me.

@TenPin

i got the same messages.
the problem is the atkbd-24-compatibility patch wich is part of the mm sources since linux-2.4.20-test9-mm3.
reverse this patch ( -R ) and the errors are away

i've noticed no other difference so far

BtW i got a standard cherry keyboard on a desktop pc.. i dont know wich key produces this error. it occurs when i log in and x is coming up

Removing that patch doesn't help in my case because test10 vanilla gives an error when I press a key that I want to use, hence xev doesn't detect the keypress, otherwise everthing is great with test10 and mm.

I too had problems with my keyboard with the 2.6 kernel. I've tried so far the mm-sources test9 and test10, as well as development-sources test9 and test10.

My keyboard is a Compaq "Easy Access Keyboard" (although my comp isn't a compaq anymore). And the extra buttons along the top work great in gs-sources using the lineakd program, but only some of them work in 2.6. I think some of the keyboard mappings have changed.

I'd like to know if this is a universal issue or if there's something we need to do to correct it.

I'm having similar issues with my MS Office keyboard in 2.6 (Gentoo sources for test11). Some of the multimedia keys work, some don't. Dmesg adds this for the ones that don't:
keyboard.c: can't emulate rawmode for keycode 245

DJ_Grijander · Post by **DJ_Grijander** » Mon Dec 08, 2003 12:34 am

Add another one to the list. This is what I get with kernel 2.6.0-pre11 vanilla sources and one of my internet keys:

Code: Select all

atkbd.c: Unknown key pressed (translated set 2, code 0x154, data 0x1a, on isa0060/serio0).
atkbd.c: Unknown key released (translated set 2, code 0x154, data 0x9a, on isa0060/serio0).

I seems that the system actually reads a keycode (154), but it doesn't run the associated action. Definitely, it seems that something is wrong with the new kernel and the keyboard driver...

Well, problem persists with 2.6.0-stable.
Even my "vanilla" ps/2 keyboard behaves very funky.

No idea whatsoever of what to do.

maw · Post by **maw** » Thu Dec 18, 2003 9:55 pm

Mine just comes up strange... X handles the key map fine, the basic letter keys all work, on the console, but after that...

# seems to have turned into 'switch to previous vt'
Shift-3 (which should give me £ as I'm on a UK keyboard and keymap) gives me ú

Other similar oddities happen with other keys. I have no idea what's going on here... this is with 2.6.0 final, my keyboard is a Logitech Cordless Comfort, UK layout, connected with USB.

Vanquirius · Post by **Vanquirius** » Fri Dec 19, 2003 2:11 am

Considering that everything is working fine in X, I suppose I can let go having the keyboard work properly in console. However, it is still very annoying to see @^ sprawling around my screen as my computer boots. I wonder, is there any way to effectively block any keyboard input in console? (leaving me with just X support...) It might sound like a stupid idea, but the console is of no use for me if I can't even login because of the funky keyboard problem. Thanks for any help.

I just installed 2.6 today, and I have this keyboard error as well (only some multimedia keys work and "Unknown key released" errors in dmesg). Just wanted to hear if anyone has found a solution? My keyboard is a microsoft natural keyboard.

Andersson · Post by **Andersson** » Mon Dec 22, 2003 3:51 am

I've been googling around looking for a solution, and even if I haven't found one I thought I'd post a few links about scancodes, keycodes, keymaps and non-standard keyboards. Just in case anyone wants to keep looking. I'll manage without those four keys for a while...

Some background on how keyboards work in linux:
http://www.tldp.org/HOWTO/Keyboard-and- ... WTO-2.html
http://www.win.tue.nl/~aeb/linux/kbd/scancodes.html
http://rick.vanrein.org/linux/funkey/

About the atkbd.c: Unknown key pressed error:
http://testing.lkml.org/slashdot.php?mid=337181
Here's a longer thread with a little more background on this problem:
http://seclists.org/lists/linux-kernel/ ... /0182.html

There is a fix suggested for that problem in those threads, to edit /usr/src/linux/drivers/input/keyboard/atkbd.c and change the scancodes right there in the source. I tried it, but must have gotten it wrong because I still couldn't get anything from that key. Perhaps I simply didn't know what I was doing.

could you explain more clearly how to reverse the patch please?

Just try to re-apply the patch and you'll be done...

Same issue here. Gentoo-Dev-sources-2.6.1. Getting these messages in dmesg

Code: Select all

atkbd.c: Unknown key released (translated set 2, code 0x92 on isa0060/serio0).
atkbd.c: Unknown key pressed (translated set 2, code 0xd8 on isa0060/serio0).
atkbd.c: Unknown key released (translated set 2, code 0xd8 on isa0060/serio0).
atkbd.c: Unknown key pressed (translated set 2, code 0xd7 on isa0060/serio0).
atkbd.c: Unknown key released (translated set 2, code 0xd7 on isa0060/serio0).

with some of my extra function keys. Some seem to work, and some don't. They all used to work with the old kernel. Has anyone found a fix or a hack yet? I was just going to copy the old 2.4.24 keyboard.c to the new kernel and replace it, but they are very different files, and from looking at the new layout, I don't think that the old keyboard.c can replace atkbd.c in the new 2.6 series.

I have the Microsoft Wireless Natural Multimedia Keyboard and Wireless Intellimouse Explorer V2.

With the stock 2.6 kernels i can't log in to the system (i don't start with X running). I can typically type 'root' hit return and then i just get a constant string of $$$$$$$$$$$$$$$$$$$$$$4 appearing with will comtinue forever until i press the volume up/doen buttons a few times, then all key non letter buttons on that console no longer work.

This has also been the case up until the latest mm releases where the keyboard will mow seem to type and then delete anything i type until i t sudden;y starts to work after many login attempts!!!! VERY odd.

The keyboard and mouse both use the one USB port via wireless and i don't have these problems running a Knoppix (2.4 kernel) Disc. I haven't tried a Gentoo 2.4 kernel yet, as i built this system on the 2.6 kernel and don't really wanns don grade.

Also with the mm sources, a patch was applied that got my # key working, but the lastest rc of 2.6.2 non-mm doesn't even appear to ahve this applied!!

Does anyone else experiece these same symptoms?? I can't beleive something likethis would exist in a stable kernel, everything else runs fine!!!

Any other suggestions, test, or anyone i can report my problems to??

Cheers,

Kristian

Well I just switched to 2.6.1-gentoo and lost my #~ key... I can get the # back with xmodmap but it's not having the ~ at all, except in combination with modeswitch :S

What DID they do to the keyboard map in 2.6???

jingo · Post by **jingo** » Mon Feb 02, 2004 9:53 pm

Found this patch ... is this what is already in the mm?

http://www.spinics.net/lists/kernel/msg236787.html

I would think it should apply to my gentoo-dev-sources 2.6.1 kernel source, but I am having troubles applying it.

Anyone know if this solves the problem?

try the latest mm sources, they will get you back a normal ~# rather than having to resort to xmodmap (which only applies to X doesn't it?) The latest mm sources have the fix for that (which i read somewhere was caused by a kernel developer from SuSE not thinking that particular key was used, don't quote me on that though)

Seems like my other problem of the scrolling $$ is not that common, at least the #~ is fixed now, i await every new kernel release in hope it fixes it.

I found a patch which I was able to manually apply to 2.6.1-gentoo, which has sorted things out in X, but the console's still mucked up. I'll try mm sources another day I think.

How did you apply it?

maw · Post by **maw** » Tue Feb 03, 2004 10:23 am

No, it was a much simpler patch than that. Unfortunately I've lost the URL... the patch was by the same person though, so I suspect what you've found is a newer variant, especially given the reference to -mm3.

The one I did was only one hunk, so it was easy to do by hand.

I've exactly the same problem with my Microsoft Wireless Natural Multimedia Keyboard and Wireless Intellimouse Explorer V2.

In my experience microsoft hardware is pretty damn good (a lot better than their software anyway!)

I'm not sure I can help with the keymap problems, but for the people with multimedia key problems, have you tried using lineak?

http://lineak.sourceforge.net/

I've not had any problems getting this to work (mind you, I've not tried using the "volume" and "mute" buttons yet but thats a whole new thread

)
