Ubuntu 7.04/Issues/Scrolling feature on touchpad does not work
From DellLinuxWiki
Description: Scrolling feature on touchpad does not work.
Systems Affected: Inspiron 1420n.
Impact: Scrolling sideways and up/down on touchpad does not work.
Workaround: Install package psmouse-dkms_2.6.20-16.29-1_all.deb and then reload the module:
$ rmmod psmouse $ modprobe psmouse
To enable horizontal scrolling, change the parameter HorizScrollDelta in /etc/X11/xorg.conf from 0 to 50, or run the following script:
#!/bin/bash sed -i '/\W*Option\W\+"HorizScrollDelta"\W\+"0"/s/"0"/"50"/g' /etc/X11/xorg.conf
Finally, restart the graphics display manager by pressing Ctrl + Alt + <Backspace> at the same time.
Fix: Work in Progress. See LP129477.
