Re: Kubuntu on a USBDrive, and a Gigabyte Tablet

First a couple of caveats; I don't have a touchscreen and this is a very narrow (as in few similar users here) problem so you might need to look elsewhere for help with this.

Keeping that in mind, my first guess is your touchscreen has been configured as a touchpad rather than the multitouch screen you desire, thus leaving your actual touchpad un-configured.

Usually, the trouble shooting process for hardware is:
1. determine if your hardware is detected properly
2. determine how your hardware is connected (pci but, usb bus, HAL or UDEV...)
3. determine if their are any specific drivers or settings required that are not included in the kernel or from your distro
4. lots and lots of trial and error

Steps 1+2)

In a terminal window, try lspci, lsusb, and sudo lshw and look for entries relating to your touchpad and touchscreen.

Read the file /var/log/Xorg.0.log and look to see if your touchpad/screen have been auto-configured incorrectly by X.

If you have the file /etc/X11/xorg.conf read it also.

Here's a link to multitouch > https://wiki.ubuntu.com/Multitouch Remember Kubuntu is Ubuntu with a better desktop but Ubuntu is the "mothership" so searching for help with Ubuntu might reveal more helpful information.

Here's a short list of similar hardware http://gestureworks.com/features/sup...00p-tablet-pc/. You might have success finding a similar screen product under a different brand name that someone has already done this on.

Once you done the commands I suggested above - if you need help deciphering these, post the output here and we'll help you figure it out.

Thanks for the reply. Meant to get to this last night, just didn't have the time.

Got the outputs from lspci and lsusb

I was able to get the output from lshw, but it was exceedingly long, so I'll skip it for now.

this looks like the relevant information from xorg.0.log

Code:

(--) IDEACOM IDC 6650: touchpad found
(II) config/udev: Adding input device IDEACOM IDC 6650 (/dev/input/mouse1)
(II) No input driver/identifier specified (ignoring)

i don't have the log file at /etc/X11/xorg.conf, but I found an interesting line in the xorg.0.log:

Code:

(==) Using config directory: "/usr/lib/X11/xorg.conf.d"

So I checked out the directory and found files on evdev, synaptics, and wacom.

Any help interpreting these wound be appreciated. It looks like my touch Screen might be input/event6 and my touch Pad might be input/mouse1.

Re: Kubuntu on a USBDrive, and a Gigabyte Tablet

I'd start by install the xserver-xorg-input-evtouch driver and restarting X just to see if it works by itself.

Next, try creating file /usr/share/X11/xorg.conf.d/99.idc.conf and putting this in it:

Code:

Section "InputClass"
 Identifier "IDEACOM touchscreen class"
 MatchProduct "IDEACOM"
 MatchDevicePath "/dev/input/event*"
 Driver "evtouch"
 Option "MinX" "0"
 Option "MinY" "0"
 Option "MaxX" "8192"
 Option "MaxY" "8192"
EndSection

This should get it working a bit, then you'll have to figure out your multitouch!
