My laptop has a dodgy trackpoint attached to the passthrough port,
although the touchpad works fine. Before 2.6.1 this didn't matter,
because whether by accident or design, the passthrough was disabled.
Does this patch disable the passthrough port by default? If not,
would it be possible to add a boot parameter or something to allow it
to be disabled?

It is my understanding that by setting "Protocol" to "auto-dev" and
"Device" to "/dev/psaux" you can freely switch between 2.4 and 2.5.

Does the touchpad sensitivity is OK for you when using then native XFree
driver? Should we bump it up a little?
Plus, there were issues in mousedev regarding PS2 emulation for touchpads
in absolute mode, it should be fixed in -mm or you can try grabbing patches
from http://www.geocities.com/dt_or/input/2_6_1/
You are probably mostly interesed in one that deals with mouse jitter.

Why would you document something that is deprecated? It was removed so the
new users would not start using it instead of psmouse.proto. psmouse.noext
should be gone soon.
Plus, you not only disabling Synaptics extensions but Genius and Logitech's
ones as well.

Is there way to make it work with gpm, too? I'm using that
heavily. Currently I'm doing gpm in repeater mode, then X reading from
/dev/gpmdata....

I work with this setting for a couple of weeks now switching between 2.4
and 2.6. The touchpad works quite well in X. (Dell inspiron 8000).
I only notice I have to tap harder to get a click.

I'm setting it to PSMOUSE_IMEX, that's just below PSMOUSE_SYNAPTICS:
#define PSMOUSE_PS2 1
#define PSMOUSE_PS2PP 2
#define PSMOUSE_PS2TPP 3
#define PSMOUSE_GENPS 4
#define PSMOUSE_IMPS 5
#define PSMOUSE_IMEX 6
#define PSMOUSE_SYNAPTICS 7
That should turn off just synaptics, no?
Okay, so how to do this properly? Synaptics driver with "mouse
emulation" is not usable (tap-to-click is critical), and I want to be
able to boot 2.4...

Well, I wouldn't mind documenting psmouse.noext, with a comment that it
shouldn't be used because it'll be removed in near future.

No. The numbers are arbitrary.

Well, if you need to boot both 2.6 and 2.4 _and_ need to use gpm and X
in parallel _and_ need tap-to-click in both gpm and X, then you have to
use the kernel command line parameter and put your synaptics into legacy
mode.
Or, the very nice thing to do would be to port the XFree86 driver to
GPM, so that GPM can understand the event protocol as well.

No problem with this patch, though it'd be better if you could provide
it against the -mm kernel for Andrew.

AFAICS, it is still psmouse*_*noext in mainline kernel, so this should

Using psmouse_proto=imps? Or something else?
Will this also result in the passthough port not being enabled?
(I'd like to disable it.)

It depends on the touchpad firmware. Most leave it enabled.
In this mode we don't have any control over the passthrough port.

You can adjust the sensitivity by changing the FingerLow and
FingerHigh XFree86 driver parameters. They control how much finger
pressure is needed before it counts as a touch. (There are two
parameters to get a hysteresis effect.)

I tried 2.6.1 with that option set as above, and also with it set to
base. In both cases I don't seem to get tap-to-click. In
2.6.1-rc1-mm1 with psmouse_noext=1, I get tap-to-click.

I notice that the passthrough appears as an extra device (mouse1 on my
system). Is there a way to disable devices from userspace? I did
find the place in the synaptics driver that looks like it is where the
passthrough port is registered, so I guess I could take that out as a
last resort. But it's a pain having to remember to patch my kernel
every time I upgrade.

You can write a program that grabs the event device for exclusive
access and then just ignores all events, like this:
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <stdio.h>
#include <errno.h>
#include <sys/ioctl.h>
#include <unistd.h>
#include <string.h>
#include <stdlib.h>
/* From linux/include/linux/input.h */
struct input_event {
struct timeval time;
unsigned short type;
unsigned short code;
unsigned int value;
};
#define EVDEV "/dev/input/event0"
#define EVIOCGRAB _IOW('E', 0x90, int) /* Grab/Release device */
int main(int argc, char* argv[])
{
const char* devName = EVDEV;
int fd;
int ret;
if (argc > 1)
devName = argv[1];
fd = open(devName, O_RDONLY);
if (fd < 0) {
fprintf(stderr, "Can't open file %s, errno:%d (%s)\n",
devName, errno, strerror(errno));
exit(1);
}
ret = ioctl(fd, EVIOCGRAB, 1);
if (ret < 0) {
printf("Can't grab event device, errno:%d (%s)\n",
errno, strerror(errno));
exit(1);
}
for (;;) {
struct input_event ev;
read(fd, &ev, sizeof(ev));
}
close(fd);
return 0;
}

Already done...

I believe the issue is that /dev/input/event0 can't be opened by
multiple things (gpm and X) in 2.4 as can be done in 2.6.
