Wierd (2 me) issues attempting install touchscreen

Thanks for making this touch screen wiki. I really need that!

I have an ACER B226HQL which have an add on IR touch screen frame. Kind of crappy quality, and only two point touch. But should be good enough for this use.

I have been able to make it work with Ubuntu 10.04. But the software I used to make it work, "Evtouch" is for some reason skipped as of Ubuntu 11. So unless I'm able to make this work I'll be stuck with 10.04.......

I'm not a programmer, so doing things from console isn't what I prefer, which I also would assume many of the others who need this Wiki will think. So the description on how to add the deb repository and such should be either linked to, or explained in detail. There are other places this is explained very well, so a link to one of those places should be OK.

I'm not sure I understand how to interpret the line saying
### USE STRICTLY FOR INSTALLING OR UPDATING XINPUT-CALIBRATOR

My problem is I don't fully understand how to do what it's saying. The only way I know how to use a repository is to add the line in the update manager and then to check for updates and apply them. But if that's not how to do it I need a detailed description of how. This is outside of normal (for a non programmer with no command line skills) way of doing things, and I have no idea on how to do the steps explained. I don't have all the details. What updates should one not install from this repository?

When I proceed and try to do the next point:

sudo apt-get install xinput-calibrator

I get the following message:

Unable to locate package xinput-calibrator

So my attempts at using the instructions are halted at that point as I don't know how to proceed now.

In general I have found touch screens and Linux to be a major pain! Almost without exception all advices on how to get your touch screen working is to replace your kernel with one with support for it. Now replacing kernels on a machine set up for LinuxCNC isn't what we want to do. So I was kind of hoping to be able to make it work with these instructions since they are written specifically for LinuxCNC users.

After all, LinuxCNC is actually an application where a touch screen is wanted by many. So there will possibly be many who will want to use these instructions.

One big wish for the future would be an application who will make all touch screens like evtouch is made a standard package in the installation files for LinuxCNC. The question is if such an application exist? Since evtouch was removed I would imagine it was replaced by something else? Of not I'm quite surprised they removed it.

And again, I really do appreciate the effort to help the likes of me to get their touch screens working. And I hope you or someone is willing to finish this wiki to a state where it's more or less fool proof and will make most users touch screens work.

Thanks for the effort so far, and keep up the good work.

Hi

These instructions are for Debian Wheezy, you seem to be using Ubuntu 10.04, they will not work with that.

I'm not sure I understand how to interpret the line saying

My problem is I don't fully understand how to do what it's saying. The only way I know how to use a repository is to add the line in the update manager and then to check for updates and apply them.

What updates should one not install from this repository?

Please read earlier pages of this thread, I went into some detail why to ZF, the sid repo is an testing, potentially unstable one, we only want one package from it and then do not want to use it again probably.

The instructions for adding the line are literal

Add sid repository to /etc/apt/sources.list

Open /etc/apt/sources.list in an editor (sudo gedit /etc/apt/sources.list from a terminal)

Add the line
deb http.debian.net/debian sid main contrib non-free

Then update apt
sudo apt-get update

Install xinput-calibrator
sudo apt-get install xinput-calibrator

Open the file /etc/apt/sources.list in an editor
Comment the sid repository back out and leave it commented out so that it does not get accidentally used in the future

#deb http.debian.net/debian sid main contrib non-free

regards

post the errors to the thread and it can be picked up if need be

Anyone can edit the pages on the wiki so take charge!

Thank you John. I'll go read up and figure it out.

Anders -

Good to see you over here. Yes, I can do that. To be honest I was considering making some changes when I correct my errors anyway, for exactly this reason. I want to make sure that it is clear to even the most uninitiated. I cannot answer your Ubuntu specific questions, but I see that Mick and Dave are already standing by to assist you. I'll post up when I've made the changes and you can tell me if it helps you understand it more clearly. Thanks for the feedback.
