Linux keycodes and left cursor on Pismo

Linux keycodes and left cursor on Pismo

[Michel Dänzer]

After switching to Linux keycodes (and Debian's i386 us keymap), the left
cursor key doesn't generate a keycode anymore. Interestingly, it works in X
with Xkb, but not without.

Anyone else sees this?


Also, what is the key combination for the Magic Sysrq on a Pismo?

Check the dev and user archives, I think this has been discussed a
few times since the new input layer backport went in.

For xmon it's <cmd><Power>. I'm not sure the Linux SysReq facility
is supported for PPC, I've never seen it enabled in Ben's .config
files and there is no sign of it in the archives.

However, invoking xmon once X (at least Xpmac 10) is running
will result in a microscopic xmon text session replicated 4 times
across the screen (even if you switch back to a text VT first).

F13 (keycode 0x69) works for me as MagicSysRq (ADB keyboard, kernels
2.2.x or 2.4.0-x).

Hmmm. <cmd> <power> is the xmon interrupt key (certainly on the G3 (ADB
Kbd)) - it isn't, however, the magic SysRq key.

SysRq is supported under PPC linux.

SysRq works fine on G3 and it is <cmd> or <alt> <f13> (duh... I forget which
and am not on that machine right now)...

if you grep for it in the kernel tree you can find the code (and change it
if you like).

Ah, well no F13 or equiv. combo on a Pismo. Grepping through
the sources it doesn't appear there is any bootparm or /proc
entry to change it... So changing it to 0x6f in
/arc/ppc/kernel/pmac_setup.c and rebuilding it should
give you F12 instead.

I'll do that. I checked Franz's pages on the input layer on PPC and didn't
find anything there.

This also happens with XFree86, it's because xmon assumes an 8 bit display - I
guess you are running X in 32 bpp? :)

Would be handy though.

I use that for the right mouse button emu, will it work nonetheless?

Thanks for the tip!

I've searched the archives now with no luck.

So, can anyone please solve my problem, even if it has been solved before? :)

I haven't seen this discussed, but I'll try a wild guess: What's
suspicious is that the linux keycode for KEY_LEFT is 105=0x69, the same
as the old mac keycode for SYSRQ_KEY. You could easily verify this by
pressing LEFT plus s or t or something and see whether it does some
emergency sync or whatever. Just a guess.

Serach on keymap around the late-June through Aug. period. I don't
think any of them specifically addressed your left key problem, but
rather the need for new, and as of then non-existent, keymaps to use
the Linux keycodes mode.

Debian has i386 keymaps which work with Linux keycodes, but thanks anyway.

Martin's suggestion about the keycode clashing with Sysrq sounds promising.
I'll report back tonight.

But a good one! That's exactly the issue. I wonder how it has worked with Xkb
in X though...

As Magic Sysrq seems to always use ADB keycodes anyway, I'll not use it for
now.


Thanks,

Michel

Sorry for not jumping in yet, but I had to concentrate on some time
consuming gcc-2.96 and glibc-2.2 issues to get things going.

Do you have by any chance a CHRP machine? I haven't touched chrp_setup.c yet.
If not, what exact kernel are you using?

BTW, there will be a new xf4 RPMs available soon.

No. (Look at the subject ;)

2.4.0-test8 rsynced from bk-devel some days ago.

It worked fine (why?) in the X from the test debs, which contain your X stuff
AFAIK.
