[gentoo-user] gpm (X11): touchpad OR usb-mouse?

[Jarry]

Hi,

I have following problem: with my notebook I am mostly
using usb-mouse, but sometimes I'm too lazy to pull it out
of bag (or I forget to take it), and in such a case I must
use Synaptics Touchpad.

Both of them work with gpm (in console), problem is that
when mouse is attached, I can move cursor with both a mouse
and touchpad.

Is it possible to configure gpm so, that if usb-mouse is
attached, then only mouse can be used as pointing device?
And if no mouse is found, then (and only then) touchpad
works? Problem is I do not know how to turn touchpad off.
There is a button for it, but apparently it works only with
windows-drivers...

And btw, I would like to have similar "auto-switch"
configuration for X11: Is it possible (without switching
manually config files)?

You may try to use udev for that. It can call scripts when devices are
plugged in and out or just present at boot (using coldplug for older
udev versions). You can let the script switch configuration files and
send gpm a signal that lets it read its configuration again. The key is
that you should not use "/dev/input/mice" as the device but have two
separate gpm configurations with "/dev/input/mouseN" (you can also use
udev to give more persistent names).

Sorry, I can't go much into practical details, I've no use for this,
personally :-)

This looks a bit complicated, since as far as I know GDM uses Xorg's
configuration to discover how to use mouse/keyboard, so, if you're
going to have more than one configuration, wouldn't it be necessary
for you to restart the X server? I too have a laptop, but for mine the
switch button for the synaptic touchpad really works :) turning it off
completely both in win and lin.

A friend told me once that he wrote a udev rule that recreated a
device every time he plugged in and out his USB mouse, this way, when
plugged out, the device pointed to the touchpad, while plugged in, it
references the USB mouse.

Can GDM do this? Sorry, couldn't find anything in the docs about it...

wowowow, sorry, misunderstood the GDM, GPM difference... Ignore the

For X11, this can also work, if you use the synaptics driver in X,
since you can have your rule call syn-client to modify the TouchpadOff
setting.

I have wanted to do this for aaages, but I always thought it was
impossible - until I noticed I have:
/dev/input/mice
/dev/input/mouse0
/dev/input/mouse1
/dev/input/mouse2

If I `cat /dev/input/mice` I get output when I move either my stick
(yeuch), touchpad, or usb mouse.

However, mouse0 only gives output for the stick, mouse1 for the
touchpad, and mouse2 for the usb mouse.

Perhaps this is the answer - you might need to change MOUSEDEV
in /etc/conf.d/gpm depending on what you have plugged in.  For X, you
would have to change Option "Device" from "/dev/input/mice" to a
specific /dev/input/mouseX.

I don't know how to do this automatically, nor how to make X use a
different mouse without restarting...

Hope this helps you on the way though.

Would a symlink help here? Link the touchpad to, say, dev/input/mymouse
then override this link with one to the USB mouse when it is plugged it.
Then use the symlink is xorg.conf.

I guess that depends if X tries to be intelligent (like some apps) and
finds the target of the symlink at startup, instead of just using the
symlink.  Also, I don't know what would happen if you pulled the symlink
while it was being used...  one way to find out :)
