2.5 bk, input driver and dell i8100 nib+pad

2.5 bk, input driver and dell i8100 nib+pad

[James H. Cloos Jr.]

Trying out 2.5, I've got only a partially working mouse.  The usb
mouse is fully functional, as are both sets of buttons on the
notebook.  The mouse pad works, but the nib is ignored.

Of course, I only ever use the nib and only noticed that the pad was
working by accident.

I seem to recall a similar post some time back, but cannot find it in
my archives.  

Any ideas?

I do need to reboot into 2.4 and clone my bk clone from the sbp2 disk
to the internal disk (ohci1394 is b0rked ATM) to see the .config I
ended up with....

The relevant X config is:

Section "ServerFlags"
  Option       "AllowMouseOpenFail"
EndSection

Section "InputDevice"
  Driver       "mouse"
  Identifier   "Mouse[1]"
  Option       "Device" "/dev/psaux"
  Option       "InputFashion" "Mouse"
  Option       "Name" "AutoDetected"
  Option       "Protocol" "ps/2"
  Option       "Vendor" "AutoDetected"
  Option       "Emulate3Buttons" "on"
EndSection

Section "InputDevice"
  Driver       "mouse"
  Identifier   "USBmouse"
  Option       "Device" "/dev/input/mice"
  Option       "Name" "AutoDetected"
  Option       "Protocol" "IMPS/2"
  Option       "Vendor" "AutoDetected"
  Option       "ZAxisMapping" "4 5"
EndSection

Section "ServerLayout"
  Identifier   "Layout[all]"
  InputDevice  "Keyboard[0]" "CoreKeyboard"
  InputDevice  "Mouse[1]" "CorePointer"
  InputDevice  "USBmouse" "SendCoreEvents"
  Option       "Clone" "off"
  Option       "Xinerama" "off"
  Screen       "Screen[0]"
EndSection

I've since been playing with the docs for the SuperIO chip but I'm not 
convinced we can actually talk to all four PS/2 ports individually unless 
we reflash the 8051 firmware on it, which I don't really want to play with.

I'll give that a try.  Thanks.

The patch in the referenced post did not fix this for me in 2.5 bk
current.  The nib continued to do nothing.

You need to reboot or suspend and resume, Just unloading and reloading the 
psmouse module isn't sufficient.

Of course; I even incremented my EXTRAVERSION for the new kernel, and
the import and compile was done in a fresh clone....

Weird. Does it come back to life if you suspend to RAM and resume? Does the 
'mouse' get detected as a Synaptics Touchpad by the changed psmouse.c?

I have to do a new compile with the csets from overnight for the htree
bug before I can test that.  But from /var/log I see:

    kernel: input: PS/2 Synaptics TouchPad on isa0060/serio1

with the patch and w/o the patch I had:

    kernel: input: PS/2 Generic Mouse on isa0060/serio1

so that part of it at least was fixed.

I've some more data on this.  I'd had been some time until I was able
to get a 2.5 to boot enough to run X....

Anyway, at 2.5.50 + a few csets, I had a spot where gpm could see the
nib iff /dev/mouse was symlinked to /dev/input/mice (c 13 63) but not
if it was linked to /dev/psaux (c 10 1) as it had been.

I hoped from that that X would also work, but I've not been able to
replicate that success even with gpm.  I don't know what magic insmod
made the difference (I wasn't trying to get it to work at the time,
just accidently hit the nib while at run level 3 and saw the gpm
cursor...).

As for a susend/resume cycle, this box has never been happy to do that.
