Same problem here with SONY VGN-FS415S and Edgy. According to the workaround at http://ubuntuforums.org/showthread.php?t=275564 , after starting X, I have to restart X (by Ctrl-Alt-Backspace) to get the touchpad functionality from Dapper back. This works but is annoying.
What's interesting is that on startup (i.e. before _re_start of X), syndaemon does load but neither a "syndaemon -d -t -k" or a "synclient var=[whatever]" does anything. They do not return error messages though. ** Attachment added: "xorg configuration file" http://librarian.launchpad.net/5174412/xorg.conf -- Problems with Alps touchpad after upgrade to Edgy https://launchpad.net/bugs/69152 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
