The file in the workaround does not exist. In Lucid, apparently, that file has been judged obsolete and been removed. There's probably a file which does the same, or some other workaround that will do this every boot.
I attached an .sh file for the convenience, and I changed 'sudo' to 'gksudo' so you'll get a graphical interface question for the root password instead of a commandline version. You can download it in your /home directory, and make it run every boot by going to System -> Preferences -> Startup Applications and click on 'Add'. Type anything in the name section, and type this command in the command section: sh ~/workaround.sh I don't know whether this works though. I don't have this bug anymore for some strange reason (without workaround). So I can't test it... And again, the workaround is not mine. ** Attachment added: "workaround" http://launchpadlibrarian.net/45909624/workaround.sh -- [10.04] Touchpad stops working after login https://bugs.launchpad.net/bugs/549727 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
