    Vostro 1510 - Touchpad not detected when booting up with power cable attached

    Running Ubuntu 10.10 with Gnome

    When power cable is attached touchpad is not detected. When removing power cable for first 5 seconds during bootup and then re-attaching, then touchpad works fine. Not using a mouse, so don't know if it is also problematic. Using generic chargers, not a Dell charger, but everything worked fine with generic chargers on Ubuntu 9.04 - 10.04.


    xinput list
    ⎡ Virtual core pointer id=2 [master pointer (3)]
    ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
    ⎜ ↳ PS/2 Mouse id=12 [slave pointer (2)]
    ⎜ ↳ AlpsPS/2 ALPS GlidePoint id=13 [slave pointer (2)]
    ⎣ Virtual core keyboard id=3 [master keyboard (2)]
    ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
    ↳ Power Button 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)]
    ↳ Integrated Webcam id=10 [slave keyboard (3)]
    ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]
    ↳ Dell WMI hotkeys id=14 [slave keyboard (3)]



    When booting up with power cable, these two are not found 90% of time, 10% of time these are somehow discovered when clicking the touchpad buttons during startup:

    ↳ PS/2 Mouse id=12 [slave pointer
    ↳ AlpsPS/2 ALPS GlidePoint id=13 [slave pointer


    When booting up on battery power, touchpad is detected 100% of time.

    How does it work in a live boot of 11.04?

    That is often the problem. Testing before installing is the only way of knowing how it behaves on your hardware.

    well, i have been using ubuntu since 9.10....... it's not like for every release after 6 months, we download the whole ISO, then test drive it in live mode and then install........ we always UPGRADE when a new stable version is released.

    and just so on the topic, my problem with touchpad not detected is not a reproducible problem..... sometimes it is detected during start-up....... and sometimes it is NOT detected during start-up......... if it's not detected during start-up, then i have to repeatedly restart the machine until ubuntu detects my touchpad.......... i don't think using a live test drive would have helped in understanding the problem which is not reproducible.

    Who are 'we'?

    I could never dream on anything else than a fresh install. If you take a look around in the fora these days, you will see a whole lot of problems being caused by a bad upgrade and solved with a reinstall.

    Feel free to believe that an upgrade should work, and I agree with you on that. Reality is just otherwise.

    Sort of defeats the point of having upgrades if they can only be used to do a clean install from scratch. Also sort of defeats the point of having a help forum if you just use it as a place to be a know it all **** with no actual useful suggestions, Morgaes.

    I have the same exact problem after maverick to natty upgrade, also occurs intermittently, will post fix here when I fix it. I had this problem on a long ago previous upgrade on the same machine, I think from 7 to 8, and was able to find a workaround that permanently fixed it until now (which I think I didn't save a copy of the terminal from unfortunately) but I can re-fix it and then will post here.

    Thanks guys. This weird *** bug was driving me nuts and this particular laptop of my friends had a completely dead battery, so the grub kernel commands worked perfectly!
    Just another example of how Linux and the Open Source Community just plain ROCK!!!!
