I also have this problem with the ALPS GlidePoint trackpad on my HP Mini 311 on Lucid Beta 2. The buttons and tap to click work but edge scrolling quite working, changes to "Mouse Preferences" have no impact and 2-finger scroll is grayed-out of mouse preferences. This was working until a daily build approximately 2-3 days ago.
