Touchpad scroll-wheel under Ubuntu 5.10 Breezy on Toshiba Satellite 2410


Quite experienced (years, not skill) with Mandriva, I just put Ubuntu 5.10 on my Toshiba laptop (Satellite 2410). Ubuntu did not manage to (get the video resolution right or) figure out the touchpad on this laptop.

Originally the mouse was nearly useless -- it wouldn't allow me to scroll down in any window's scroll bar (would jump back to top, etc). That was with

Quote:
Section "InputDevice"
Identifier "Mouse1"
Driver "mouse"
Option "Protocol" "PS/2"
Option "Device" "/dev/psaux"
Option "ZAxisMapping" "4 5"
EndSection
in xorg.conf.

Much better performance is with
Quote:
Section "InputDevice"
Identifier "Synaptics Touchpad"
Driver "synaptics"
Option "SendCoreEvents" "true"
Option "Device" "/dev/psaux"
Option "Protocol" "auto-dev"
Option "ZAxisMapping" "4 5"
EndSection
But the scroll-wheel (Zaxismapping) still does not work at all, and neither do various other functions: for instance, unlike in Mandriva, I can't drag with the touchpad (by tapping and then pulling).

Does anyone know the magical incantations here? Isn't there a GUI to help figure out which device / settings etc to use?

I have found the command line tool "xev" which shows all x input events very useful.

I have been confused about this "synaptics" business. It seems that some touchpads are "Synaptics" (brand?) but the driver claims that mine is ALPS instead, but it seems that the synaptics driver might deal with those okay too? Well, not well enough, seemingly.

Under Mandriva, I use
Quote:
Section "InputDevice"
Identifier "Mouse1"
Driver "mouse"
Option "Protocol" "ExplorerPS/2"
Option "Device" "/dev/mouse"
Option "ZAxisMapping" "6 7"
EndSection
and things are nice. This (with /dev/psaux) gives useless, jumpy (upward-pulling) mouse under Ubuntu. I have tried "6 7" for zaxis under Ubuntu, too: no good.

At the moment, the X log says:

There are plenty of threads on ALPS touchpads in the Ubuntu forums. Start by searching that forum for "alps" and you will get plenty of helpful posts.
