Comment 40 for bug 195009

David, glad it worked for you! I tried the same (despite knowing better - i've tried modprobing several times), and tpconfig also finds the touchpad without problems, but modprobing doesn't change anything. Also no touchpad in .../devices. Well, yours has worked once with Gutsy (I assume) - mine hasn't worked since Feisty. Hopefully there will be someone finding a pattern here, who can fix whatever is holding the touchpad from being found during boot.
