    Touchscreen gateway cx210x configuration

    I recently purchased a gateway cx210x, it came to me with ubuntu 12.04 as the OS. I have been trying to get the tablet portion of this computer to work but for some reason the calibrate touchscreen application gives me an error telling me that, there is no calibratible device found.
    CAN ANYONE HELP ME WITH THIS ISSUE, this is my first experience with ubuntu so please keep it in lamens....
    THANKS!!!!

    Hi Hollinheadk,

    Welcome to Ubuntu forums!


    Does the digitizer (stylus) work at all?

    Re: Touchscreen gateway cx210x configuration

    also just some added info, I have double checked that utouch and xinput are installed and up to date. I really don't know what else to do, my knowledge with windows products tells me that there may be a hardware issue or possibly a driver missing, but since I am a newbie to ubuntu I don't even know if that makes sense!!!

    Alright. I think it should be a serial tablet PC. Open a terminal and run this command.
    Code:
    lsusb
    If no tablet shows up in the list usb output then it likely is serial.

    Then let's see if the digitizer is on a serial port and which one. In the terminal run this command.
    Code:
    sudo dmesg | grep ttyS
    And please post the outputs of the above two commands.

    If we get the port then lets try to determine if there is output on that port i.e. does the digitizer work? Run this command:
    Code:
    xxd /dev/ttySX
    Where X is the number of the serial port.

    xxd (hidrawX hexdump) will exit for devices not listed, otherwise CTRL and C to quit. Bring the pen to the screen and move it around. You know you have the right ttyS* when you see a reaction with an output of characters.


    The driver is probably the fpit driver. That was last worked on by a Xorg guru about a year ago. After he got it cleaned up and building correctly he announced that support was being stopped but he would update it if users contributed tested code.

    Unfortunately we've tried a couple of times to set up fpit serial tablet PCs without luck. It could be the code doesn't support that. The developer may have inadvertently broken it for serial tablet PCs because he didn't have any testers to give him feedback. Or we might have messed up the setup. I don't think either of the two users were very advanced.

    I did write up some tablet PC .conf files for the fpit driver but the Xorg developer wouldn't take them unless they were tested and worked. Which makes sense of course. I still have them around somewhere I think.

    ok ran the first command and got this
    Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
    Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

    ran the second command you advised and this was the response

    Usage:
    dmesg [options]

    -C, --clear clear the kernel ring buffer
    -c, --read-clear read and clear all messages
    -D, --console-off disable printing messages to console
    -d, --show-delta show time delta between printed messages
    -E, --console-on enable printing messages to console
    -f, --facility <list> restrict output to defined facilities
    -h, --help display this help and exit
    -k, --kernel display kernel messages
    -l, --level <list> restrict output to defined levels
    -n, --console-level <level> set level of messages printed to console
    -r, --raw print the raw message buffer
    -s, --buffer-size <size> buffer size to query the kernel ring buffer
    -T, --ctime show human readable timestamp (could be
    inaccurate if you have used SUSPEND/RESUME)
    -t, --notime don't print messages timestamp
    -u, --userspace display userspace messages
    -V, --version output version information and exit
    -x, --decode decode facility and level to readable string

    Supported log facilities:
    kern - kernel messages
    user - random user-level messages
    mail - mail system
    daemon - system daemons
    auth - security/authorization messages
    syslog - messages generated internally by syslogd
    lpr - line printer subsystem
    news - network news subsystem

    Supported log levels (priorities):
    emerg - system is unusable

    I assume you garbled sudo dmesg | grep ttyS. That's the output you get when you haven't entered a command correctly but at least dmesg was recognized as the command you were attempting to use. Try again. It should ask you for the password. Just copy and paste.

    Re: Touchscreen gateway cx210x configuration

    but, I don't know if this helps when I do sudo dmesg it gives a very long description of everything on the computer, or at least I think that is what it is...

    Re: Touchscreen gateway cx210x configuration

    Right that's the output on dmesg's ring buffer. It's big but not endless and so newer stuff starts over writing older stuff, hence ring. That's why we are using the grep command to just pick out anything to do with serial ports or ttyS.

    Alright try just:
    Code:
    dmesg | grep ttyS
    If still nothing that is puzzling. We do need to figure out the port. I wonder if setserial needs to be installed or what. What do you see when you run:
    Code:
    setserial -g /dev/ttyS*
    By the way I just realized we might be able to use input-attach instead of fpit. That would avoid the fpit problems if it worked.
