Hello,
About a year ago, Chase Douglas suggested I post about this here. I've only
recently become annoyed enough to finally do so.
When I add a secondary monitor horizontally to my primary one, my synaptics
touchpad (on a Thinkpad W510) becomes much more sensitive horizontally than
vertically. If I add the secondary monitor vertically, it becomes more sensitive
vertically than horizontally. Others have reported the same issue on different
machines. Here are the relevant bug reports:
https://bugs.freedesktop.org/show_bug.cgi?id=31636
https://bugs.launchpad.net/xorg-driver-synaptics/+bug/726832
Surely this can't be a design feature, can it? No other input devices (external
mouse or trackpoint, both via evdev apparently) behave this way, and neither
does the touchpad in Windows. This essentially breaks the touchpad for me on a
multi-monitor setup. Fortunately, when plugged into an external monitor, there's
usually access to an external mouse, which is perhaps why this one has flown
under the radar for so long. This bug has been around for coming up to a year
and a half. Could someone maybe have a look at it?
I have heard from a few people that they actually prefer this behavior.
I think we either need to stick with what we have or make it
configurable (and maybe change the default).
Peter, any thoughts?

Chase, I find it incomprehensible how anyone could want this behaviour. Did any
of them explain why they prefer it? Could you maybe get them to comment on this
thread?
Again, the inconsistency with the multi-monitor behaviour of other pointing
devices within Linux is glaring, as is the inconsistency with touchpads on other
OSes. It would seem to me that going against the consensus across pointing
devices and OSes (at least, as perceived by myself) should require extraordinary
justification.
I don't have much experience with Macs. Can anyone say for sure how the touchpad
behaves in a multi-monitor setup on OSX?
Martin
