Note that "multi-touch" for this device is basically going to be two-fingered scrolling. The data isn't good enough to do much more with it. > For me, when I install psmouse-alps-dkms > > 1. Nothing changes until I reboot Yes, installing the dkms package doesn't load the new driver. Theoretically you just need to unload/load the psmouse driver, but that might hang your machine if it's using the Ubuntu IMPS/2 emulation support (a fix for this was recently put into oneiric, but I don't think it's been released yet). > 2.

If it works in the window manager but not on the desktop, I don't think the driver is to blame. You can prove this by switching to a virtual console (e.g. Ctrl-Alt-F1) and running 'sudo lsinput', finding the Alps touchpad device, and then running 'sudo input-events' with the device number of the touchpad. If you see output spewing on the screen then you move your finger on the touchpad, the driver is probably working correctly. If it is working correctly, the problem would seem to be elsewhere. I'm not very familiar with debugging problems in those areas, but I'll share what I do know. Return to the desktop (Ctrl-Alt-F7), open a terminal, and run 'xinput list'. You should see an "ALPS DualPoint Touchpad" device listed, followed by an id number. Run 'xinput --list-props <id>' using the id for the touchpad. At the top there should be a line labeled "Device Enabled", and the value should be 1. If it's not, run 'xinput --set-prop <id> "Device Enabled" 1' and see if your touchpad works. If your device isn't listed or it still doesn't work, I'm not sure what to look at next. Probably the best thing is if you attach /var/log/Xorg.0.log, and I'll take a look at it. > I've attached the output of dmesg.txt. Okay, you're using v4 with the extra debugging, so I can see that the driver is processing packets from the touchpad. There are several large gaps in the timestamps, which I'd guess means that some of them are after you logged into the desktop environment. Which is what I'd expect to see. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-synaptics in Ubuntu. https://bugs.launchpad.net/bugs/550625 Title: Alps touchpad is recognized but synaptics clients and scrolling do not work To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/550625/+subscriptions _______________________________________________ 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
