[gentoo-user] Combining multiple pointer devices into one

[Willie Wong]

Hi list, 

When I look at /dev/input I see the devices mice, mouse0, mouse1,
mouse2, mouse3. The first one, mice, seems to be a combination of all
other mouse devices. 

On the console I want to use gpm to get a pointer, but gpm can only
take one MOUSEDEV entry at a time (as far as I know), so currently I
have it set on /dev/input/mice. Ideally, however, I only want to use
mouse0 and mouse2 on the console (mouse1 is actually a touchscreen and
its output is "junk" from the point of view of the ps2 driver, and
actually causes problems). 

How does one create, using udev, an input device that aggregates just
the data from mouse0 and mouse2? 

Thanks, 

W

Do you mean for X, or a /dev/ node for gpm ? Like /dev/input/most_mice ?

For the first, this is configurable in xorg.conf. No clue about the second.

The second. Like you said, in xorg.conf I can select multiple pointer
devices, so there's no need to worry about X (and in fact the X events
driver is capable of dealing with the touchscreen). So yes, I would 
like something in the spirit of /dev/input/all_but_one_mice. 

Thanks
