Hi,

I have just installed lucid 32bit daily build using wubi on a Dell Latitude E6400. My touchpad previously had worked out of the box including vertical scrolling and I had the option to manipulate its settings from the touchpad tab in System>Preferences>Mouse.

However, after this lucid installation I no longer has the touchpad tab and scrolling don't work. Trying to execute syndaemon from a terminal gives me the error: "Unable to find a synaptics device." I also tried installing the package gpointing-device-settings and restarting but it made no difference.

Could somebody guide me to what I should try to get scrolling working as well as changing other touchpad settings?

Thanks in advance,
Joseph

This (http://ubuntuforums.org/showthread.php?t=1419833) is a method to simulate two finger scrolling, you can use it as a temporary workaround.

Thanks for your help but unfortunately this didn't work.

running any of the instructed commands fails with the following error


unable to find device "SynPS/2 Synaptics TouchPad"

I tried checking the name of my device through running "xinput list" and I got the following output:


⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ PS/2 ALPS DualPoint TouchPad id=12 [slave pointer (2)]
⎜ ↳ Macintosh mouse button emulation id=13 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Video Bus id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Power Button id=8 [slave keyboard (3)]
↳ Sleep Button id=9 [slave keyboard (3)]
↳ HID 413c:8157 id=10 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]
↳ Dell WMI hotkeys id=14 [slave keyboard (3)]

So I tried changing the device name in the command to "PS/2 ALPS DualPoint TouchPad" but still I get the error


unable to find device "PS/2 ALPS DualPoint TouchPad"

I am no expert so please instruct me if I am doing something wrong.

For starters ;) Put code in code boxes not in quote boxes (the # button at the top of the post editor). Not that is really matters in your post, but code boxes have a max width and length and prevent smilies in the code.

Now the "real" problem. Some time last month the way devices are passed onto xinput has changed. Make sure you wrote the device name as "PS/2 ALPS DualPoint TouchPad" and not as '"PS/2 ALPS DualPoint TouchPad"'.

Also, judging by the name of your touchpad, it seems to be a real multi-touch-pad. So you might have a bug that needs to be splat. You can still use this simulation method, but true multitouch does work better than the simulation. Keep an eye on System>Preferences>Mouse and if the two finger scrolling setting reappears turn off the 2 finger simulation. And of course see if there is a bug report for your touchpad.

2 typos and 1 correct as an example:
