I also experienced this problem and also solved it by booting 2.6.31, but I have a few notes which might help other people solve this problem:
I updated my laptop this morning to 9.10. The update manager complaint about it being unable to install some packages, I didnt really read this, but apparantly this also included the 2.6.31, so I was still running the old kernel. After reading this thread I installed 2.6.31. This did not work as I need the propertiary nvidia driver in X, this was not automatically installed so X failed to start. After this I installed the kernel headers. Somehow the nvidia driver automatically patched my kernel after this. This solved my problem, i'm now able to boot X and use my touchpad once again. Hope this might help other solve their problem as i'm probably not the only one using the Nvidia driver. -- Touchpad and mouse buttons not working after upgrade from Ubuntu 9.04 to 9.10 https://bugs.launchpad.net/bugs/442441 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-synaptics in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
