Identical issue to the one originally reported with Edgy release, all packages up to date as of time of this post, on a Gateway 6525GP. Touchpad works before suspend, but stops functioning after resume and its nodes in /dev/input disappear. Issue does not manifest after hibernate.
Attached archive contains output of lspci, lsmod, dmesg, and `ls -lR /dev/input`, as well as /var/log/Xorg.0.log, each from before (./presuspend) and after (./postresume) the suspend / resume. ** Attachment added: "Logs and diagnostic output from before and after suspend / resume" http://librarian.launchpad.net/5164023/synaptics-troubleshooting-files.tar.bz2 -- Synaptics touchpad ceases functioning after suspend and resume. https://launchpad.net/bugs/59867 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
