synaptics touchpad not working with 2.4.x (fwd)

[James S. <jsi...@tr...>]

Does the i8042 drivers we have support this device?

Subject: synaptics touchpad not working with 2.4.x

I;ve had this with 2.4.0 but have just tried with 2.4.6ac2 and still
have it.

Under 2.2.x the touchpad works like a dream. Under 2.4.x it stutters,
freezes and so on. Did something about /dec/psaux change between 2.2.x
and 2.4.x? Will I need to recompile glibc and/or gpm?

if I cat /dev/psaux I get data flowing through but gpm stays frozen. :/

Hope someone can help as, now that ext3 is being well and truly ported 
to 2.4.x, this is the last stumbling block for me having 2.4.x on
my laptop.

gpm options: /usr/sbin/gpm -m /dev/psaux -t synps2 -Rmsc -2
glibc: 2.1.3 compiled for 2.2.x

We don't have a specific driver for this. It should emulate a normal
PS/2 mouse, though.

The current 2.4 code chokes on the 0xaa character this device likes to
send and resets it quite often. The ruby code is protected against this
while still capable to detect mouse reconnects (the reason 0xaa handling
is in 2.4).

2.4 can't be fixed, because of its psaux byte-stream oriented
architecture. 2.2 doesn't handle mouse reconnects. Ruby understand the
psmouse protocol and thus handles everything gracefully.

Hi Vojtech,

while you are at it, talking about ruby's psaux driver:

Does ruby allow to send data down to a psaux device? I will need this
functionality to improve the Linux support for the Twiddler2 (to allow
reprogramming of the chord-to-scancode mapping table which is kept
inside the device itself).

Thank you,
Arndt

Not from userspace yet. But you can do it from a driver that'll plug
between the i8042 driver and the atkbd/psmouse drivers.

That's fine for me! This driver could then have a /proc interface
to which user space code can write the desired mapping tables.

Thanks,
