I installed the .deb from comment #57, but it disabled the trackpad altogether, leaving the touchpoint as the only functioning mouse device. Before installing the .deb, and after uninstalling it, the trackpad is treated like a PS/2 mouse. With the .deb installed, xinput recognized the device as a "AlpsPS/2 ALPS DualPoint TouchPad", but showed its status as disabled. Using xinput set-prop to enable it was just ignored (no error message, but it stayed disabled). I'm attaching the output of xinput list-props.
This is on a Dell Latitude E6420, on Ubuntu 11.10 64-bit, kernel 3.0.0-15-generic. ** Attachment added: "Output of xinput list-props on the ALPS device" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/737051/+attachment/2640960/+files/alps.xinput-list-props -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/737051 Title: [regression] Alps touchpad detected, but scrolling not working To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/737051/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
