Public bug reported: After installing Ubuntu 11.04, my touchpad has no vertical scroll. I googled and found the defect can be solved by typing following commands:
$ echo "options psmouse proto=imps"|sudo tee -a /etc/modprobe.d/psmouse.conf $ sudo modprobe -r psmouse; sudo modprobe psmouse And as a result the touchpad scrolling is back. However, the "touchpad" tab in the "gnome-mouse-properties" is gone (see the attachment) , and I lost syndaemon support to avoid touchpad making trouble when typing. To sum up, the touchpad is either treated as a touch device with no scrolling, or a 3d-psmouse with no touch device system support. Below is the result of running tpconfig Found Synaptics Touchpad. Firmware: 8.96 (multiple-byte mode). ** Affects: ubuntu Importance: Undecided Status: New ** Tags: synaptics touchpad -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/784965 Title: Touchpad does not work properly in Ubuntu 11.04 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
