I recently upgraded my Dell Precision M90 Laptop to Ubuntu Karmic Koala. I’m running it standalone, no Windows anywhere. When I upgraded using “apt-get upgrade” my touchpad didn’t work. Nothing. The touchpad was completely disabled. I assume that this is a problem on M70’s, ect.
Found a fix after searching for two days — in case you’re having the same problem, here it is.
Open a terminal (if you don’t have a mouse hooked up, use Alt+F2). then “su” and give the root password (I tried doing this with sudo and still didn’t have enough permission. I “think” you need to be root). At the prompt, type:
echo options psmouse proto=exps > /etc/modprobe.d/psmouse.modprobe
At the next prompt, type”
Your touchpad will come back up after rebooting.
I did an apt-get upgrade just after the release was announced. It killed my NVidia driver and would boot up “once in awhile” in recovery mode. I finally got frustrated and downloaded and burnt a DVD on my Mac, wiped the disk on my Dell and reinstalled the thing. It’s working fine now — there was no bugginess in the touchpad, etc…
Ubuntu changed a lot of stuff in this release. I find it almost similar to Mac’s move from OS9 to OSX, except that Mac “warned us” that this was a big move. Ubuntu rushed this release to coincide with Windows 7 and frankly they really dropped the ball on the message, the QA and the overall polish of the product. Thank God I never trusted it enough to leave anything important on the Dell. I’ve got Macs for that all over the house that are as stable as the Pyramids. Snow Leopard was a “bug fix” release. They’ve come a long way from the pre-“Jaguar” days. Ubuntu should take note.
Funny thing is, I actually like using the Ubuntu more than the Mac, but then again, I like writing Python code in front of the TV with a cocktail…
