    11.04 beta update: bluetooth is broken and no multitouch.
    stylus still works out of the box and virtual keyboard usable...

    ok, second update: finger touch still acts as a big touch pad but you can use both stylus and finger, and not have the same issues as in 10.10 (i.e. scrambled scrolling up, etc.), been using 11.04 now for a few hrs trying different packages and no restart needed yet to restore input. Guess that's a plus, but still no bluetooth-using "onboard" virtual keyboard.

    The ppa package mentionned by you earlier (bluez something) don't work for Ubuntu 11.04?

    Thanks a lot for tying so hard to make everything working, i ordered mine yesterday. I've got something like 30 days to wait till they refill their stock.

    Re: Ubuntu on EP121 Touch screen problem

    For anyone interested in using evtouch driver, I got it working with the following procedure (I'm using amd64 version of ubuntu 10.10)

    From a clean install of 10.10 amd 64,

    1) remove synaptics driver for mouse (I just did this in synaptics pacage manager, but make sure you don't uninstall synaptics package manager!)

    2) Download egalax drivers from http://home.eeti.com.tw/web20/eGalax...inuxDriver.htm

    3) Install the egalax driver according to the instructions in the readme file UP TO the point where it asks you to restart the computer.

    4) Restart the computer, and instead of following the directions given by readme file in the directory where you downloaded egalax, open a terminal and type (without quotations)

    "cd /usr/share/X11/xorg.conf.d"

    If you type "ls" then you should see at least (I'm pretty sure this applies to all ep121's)

    10-evdev.conf 50-evtouch.conf 50-wacom.conf
    50-egalax.conf

    Open up 50-egalax.conf, i.e. "sudo gedit 50-egalax.conf" (or whatever your favorite text editor is)

    I modified mine to look like this:

    Section "InputClass"
    Identifier "eGalax touch class"
    MatchProduct "eGalax Inc.|Touchkit|eGalax_eMPIA Technology Inc."
    MatchDevicePath "/dev/input/event*"
    Driver "evtouch"
    Option "MinX" "0"
    Option "MinY" "0"
    Option "MaxX" "32768"
    Option "MaxY" "32768"
    Option "ReportingMode" "Raw"
    Option "Emulate3Buttons"
    Option "Emulate3Timeout" "50"
    Option "SendCoreEvents" "On"
    #Option "TapTimer" "0"
    Option "LongTouchTimer" "350"
    Option "ReportingMode" "Raw"
    # Option "Emulate3Buttons"
    # Option "Emulate3Timeout" "50"
    Option "SendCoreEvents" "On"
    # Option "maybetapped_action" "click"
    # Option "maybetapped_button" "3"
    Option "longtouched_action" "down"
    Option "longtouched_button" "1"
    Option "oneandahalftap_action" "click"
    Option "oneandahalftap_button" "3"
    # Option "ButtonNumber" "4"
    # Option "Calibrate" "1"
    #original parameters to use with the "void" driver
    #Option "Device" "usbauto"
    #Option "Parameters" "/var/lib/eeti.param"
    #Option "ScreenNo" "0"
    #Option "SkipClick" "0"
    EndSection

    #Section "InputClass"
    # Identifier "eGalax touch class"
    # MatchProduct "eGalax Inc.|Touchkit|eGalax_eMPIA Technology Inc.|#eGalaxTouch Virtual Device"
    # MatchDevicePath "/dev/input/mouse*"
    # Driver "void"
    #EndSection

    #Section "InputClass"
    # Identifier "eGalax touch class"
    # MatchProduct "eGalax Inc.|Touchkit|eGalaxTouch Virtual Device"
    # MatchDevicePath "/dev/input/js*"
    # Driver "void"
    #EndSection



    Note that the install is originally looking for a void driver at this point.

    Under the section that starts
    Section "InputClass"
    Identifier "eGalax touch class"
    MatchProduct "eGalax Inc.|Touchkit|eGalax_eMPIA Technology Inc."

    You will probably have "void" as the driver instead of "evtouch". I think changing "void" to evtouch as I did just forces the device to use the evtouch driver. I tried evdev driver, but it recognizes the screen as a touchpad, and I had problems using the solutions posted by others (I thikn b/c i'm using amd64)

    Anyways, the minx min y maxx maxy parameters worked for my screen (and in principle, yours) The other options are specific to how I like to set up my touch screen. See http://www.conan.de/touchscreen/evtouch.html for more details on setting up the driver. I can post my Xorg.0.log if anyone wants.

    Re: Ubuntu on EP121 Touch screen problem

    So, I tried utouch a little but, but from what I read one really needs the unity interface to use it well (there is something call jinn (...? i think) that allows one to use with gnome, but I didn't try it). I'm going to wait until 11.04 to try for gesture support, unless someone thinks there's something worth trying.

    So, today I've been working on the two buttons on top of the computer beside the power button. In syslog, they register as follows:


    Apr 11 21:46:55 paolo-slate kernel: [ 5553.957930] eeepc_wmi: Unknown key f7 pressed
    Apr 11 21:46:55 paolo-slate kernel: [ 5553.960949] eeepc_wmi: Unknown key f3 pressed
    Apr 11 21:46:55 paolo-slate kernel: [ 5554.866525] eeepc_wmi: Unknown key f7 pressed
    Apr 11 21:46:55 paolo-slate kernel: [ 5554.869479] eeepc_wmi: Unknown key f3 pressed
    Apr 11 21:48:37 paolo-slate kernel: [ 5656.106085] eeepc_wmi: Unknown key f7 pressed
    Apr 11 21:48:37 paolo-slate kernel: [ 5656.108936] eeepc_wmi: Unknown key f3 pressed
    Apr 11 21:48:39 paolo-slate kernel: [ 5657.896325] eeepc_wmi: Unknown key f3 pressed
    Apr 11 21:49:33 paolo-slate kernel: [ 5711.774609] eeepc_wmi: Unknown key f3 pressed
    Apr 11 21:49:35 paolo-slate kernel: [ 5714.295383] eeepc_wmi: Unknown key f3 pressed

    (this is for the push button with the keyboard symbol by it. the slide button that locks (not the power button) registers as combinations of f7 and f5. I'm thinking the f7 is some idle state (?) and f3 / f5 is where the computer registers the button event (I don't know anything about computers, sorry for the mangled interpretation).

    Anyways, what is wmi and how to I attach a script to these events? I'd like to have one button rotate the screen, and the other bring up onboard.

    Also, does anyone know where events associated with the accelerometer appear? are they acpi events? I'd like to enable that feature as well.

    Thanks!

    ~Paolo
