[Bug 549447] Re: eGalax touchscreen configured as tablet
I kinda started a new thread on kubuntuforums.net here it is
http://kubuntuforums.net/forums/index.php?topic=3114895.0
Basically I have a theory about entry 12 on this forum from kb1605.
This is what I posted on kubuntuforums.net. I am probably a little late
in understanding this but maybe it will help someone out.
So more research I think I maybe have a better understanding what is
going on here are parts of lshal and and xinput -list
lshal part

xinput -list output
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Logitech USB Receiver id=10 [slave pointer (2)]
⎜ ↳ eGalax Inc. Touch id=8 [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)]
↳ Sleep Button id=7 [slave keyboard (3)]
↳ Logitech USB Receiver id=9 [slave keyboard (3)]
So what I see is the first lshal entry is the "eGalax TouchScreen", the second entry is "eGalax Inc. Touch." Notice that xinput -list only has the second entry from lshal. So what I think is happening is the driver module in Ubuntu 10.10 Maverick and the current version of X is only reading the "click" part of the eGalax controller. That is why the pointer goes to the top left of the screen and than sometimes gets stuck on left click until you touch the screen again. The first entry in lshal is "eGalax TouchScreen" this part of the controller is the x,y portion and would tell the cursor where to point on the screen.
Some people get both entries for the device in xinput -list, they get the touch controller to work by disabling (using commands in xinput) to disable the "eGalax Inc. Touch" entry from the xinput -list. Therefore they only get a mapping position of where the cursor is, (without a left click). To add the click they edit the xorg.conf file and put an option in the section that says something about click on release or something similar.
I went ahead and plugged the touchscreen to my laptop booted into windows 7 installed the drivers that it came with (TouchKit) and it works fine in Windows 7. I did that just to make sure the raw data was there and everything on the touchscreen was working.
I really don't know how to do much in linux except by following
someones step by step command entries and sometimes I try my own thing
which 50% of the times ends up back at reinstall with live cd or going
into the file I messed up from live cd and changing everything back to
how it was.
What I am wondering is to get the eGalax calibration program or the
TouchKit program to work and be able to properly make a parameters file
that will configure/calibrate the touchscreen is this. After
downloading the tar ball from eGalax and making some script changes to
the setup.sh file is it possible that adding the correct MatchProduct or
Products to the InputDevice Section of xorg.conf can that somehow make
it so that the eGalax calibration program will see the touch controller?
It would also be useful to find out what the eGalax program is
specifically looking for.
So I will try some more and probably break X server and xorg.conf
again to try and figure this thing out.
