eGalaxTouch Y-Axis Issue

[deaths_eclipse]

Hi, I'm new to this forum so forgive me if I'm posting this in the wrong section. Just recently I installed (again) Ubuntu on my tablet. I've managed to get multitouch working on my screen (eGalaxTouch Controller) however the Y-axis is inverted. I've tried editing xorg.conf, 99-calibration.conf & some other files that i can't even remember anymore. I would really appreciate the help because I don't want to have to switch back to Windows. Thanks.

(I'm running Ubuntu 11.10 on an Acer Iconia Tab W500)

Hi deaths_eclipse,

Welcome to Ubuntu forums!

It probably depends on which driver you are using. But this option:

Option "InvertY"

added to the xorg.conf section or xorg.conf.d .conf file works for at least some drivers.

[deaths_eclipse]

That didn't work. Reinstalled Ubuntu twice. First try i completely messed up the touch driver and something must have gone wrong during the installation because xinput and xorg were throwing all sorts of random errors. Second time, i didn't mess with xinput or xorg but tried poking around the eGalax ini file in /etc and managed to get it fixed. Thanks for the reply anyway.

Hey guys, i am having similar issue with both axis being inverted. My situation is a bit different, i am running mini ISO on ubuntu 11.10. I can't find xorg.conf files...

here is some info from lsusb and lsmod

Hi dlinuxh,

Let's see if a kernel driver is picking it up. What is the output of this terminal command?

xinput list

If so we can use the output to see if it is on a X driver.

Thanks Favux for reply, i am new at this...
this is what I get for xinput list

xinput list

after searching more, i found this link pointing to xorg

I'm a little confused. With the 3.0 kernel you are on the Ubuntu Oneiric release? X is the windowing system, you wouldn't have a gui without X. Or are you using a Ubuntu variant?

Ah just spotted your second post there. So X server 1.10.4. So the:

xinput list

command run in a terminal is really saying?

Unable to connect to X server

Are you using a regular terminal or ctrl-alt-F2? The latter takes you out of X.

[dlinuxh]

i am running mini ISO, with no gui... the distro boots up right to full screen browser kiosk mode....
yes, i can go to console via ctrl f2, and back to browser

Ahh.

So the browser is handling the windowing, i.e. the gui? It may not even be using X. From what you are saying it recognizes the eGalax TouchScreen and has some sort of driver handling touch it even if it isn't the evdev X driver. So is there some setting somewhere in the browser preferences that let's you invert the axes for the touchscreen?

Given I don't know how the browser is handling the gui and the touchscreen can't be much help. If an option isn't available then that would seem to leave either modifying the code or perhaps the kernel driver code for it. Is this Chrome?
