Re: pre8(vger) kills button 3 on 1-button mouse

Ok, I found the reason why the keyboard is no longer sending different
keycodes for left and right option key. In my patches, I was setting the
keyboard to the highest possible handler ID for a normal keyboard (that
is 3 or 5 instead of 1) but this is wrong: at handler 5, the Apple
Extended Keyboard will not send different codes.

The kernel fix is in mac_keyb.c, line 647, replace:

	/* Enable full feature set of the keyboard
	   ->get it to send separate codes for left and right shift,
	   control, option keys */
	for(i = 0;i < keyboard_ids.nids; i++) {
	    if (adb_try_handler_change(keyboard_ids.id[i], 5))
	    	printk("ADB keyboard at %d, handler set to 5\n", keyboard_ids.id[i]);
	    else if (adb_try_handler_change(keyboard_ids.id[i], 3))
	    	printk("ADB keyboard at %d, handler set to 3\n", keyboard_ids.id[i]);
	    else
	    	printk("ADB keyboard at %d, handler 1\n", keyboard_ids.id[i]);
	}

by

	/* Enable full feature set of the keyboard
	   ->get it to send separate codes for left and right shift,
	   control, option keys */
	for(i = 0;i < keyboard_ids.nids; i++) {
    if (adb_try_handler_change(keyboard_ids.id[i], 3))
	    	printk("ADB keyboard at %d, handler set to 3\n", keyboard_ids.id[i]);
	    else
	    	printk("ADB keyboard at %d, handler 1\n", keyboard_ids.id[i]);
	}


In the meantime, you can get back the previous behaviour from userland with:

mousemode 2 3

Sorry for the inconvenient !

I removed most of my patches to mac_keyb.c before submitting them, I was
pretty sure I didn't break anything, but I was probably wrong. I'll have
a look at it as soon as I manage to get this vger tree (today probably)
and submit a new patch.

Here, I have rewritten most of the buttons handling in console and
buttons emulation, but my new version is not ready and was not included
in the patches I sent to Cort. I just checked my patches, and they should
not change anything to buttons emulation. I'll test all this later today.
Thanks for pointing this out.

Ah yes, could you send me a dmesg log ? I would like to soo how your
mouse was recognized at startup.

Let's be off-topic too ;-)

I'm looking for a place where I could order one or two 3 button mice. My
problem is that I want mice that currently cause trouble with Linux (in
order to fix them of course ;-). I'm looking for a MacX compatible one,
and eventually one of those that needs mousehack to work but I don't know
where to find them since those people don't usually put the kind of
protocol used by their mice on the web page...

So if someone could give me a set (model,place_to_buy,protocol_used) I
would be grateful !

pre8(vger) kills button 3 on 1-button mouse

[Martin Costabel]

The latest changes for 2-to-4-button mice on vger in
drivers/macintosh/mac_keyb.c (rev 1.24) break the emulation of button 3
on my 1-button Apple adb mouse.

This happens both in Xpmac, where option_right+click is hard-coded to
button 3, and in XF68_FBDev, where I use a patch by Franz Sirl for the
adb_buttons kernel command to get the same effect.

The reason seems to be that in rev 1.24 option_right gets mapped to
option_left even in raw mode (same for ctrl, BTW). I don't understand
this from the code, which is too complicated for me, anyway, but from
looking at the effect, as witnessed by xev in Xpmac, for example.

For the moment, I went back to rev 1.23 which doesn't have this problem.
