Touch Screen Calibration Tool

OldTechLover · Yesterday 00:50

Greetings,

I really love this Linux distribution and think it is very well made. I have been using it for several months now and intend to continue using it for as long as I can. I have it installed on my 2007 Panasonic Toughbook CF-30 mk.3 (which I am using to make this post). It runs the 32-bit trinity version very well and almost feels like a new computer (even though it is 18 years old as of the time of this post). I have the same version installed on another computer that is slightly less old and it runs on it just as well as it does on my Toughbook. Learning how to use linux has taken some getting used to but I have managed to "konquer " every obstacle I've encountered except for one. This single issue has had to do with the touchscreen. I have asked for help before and help was recieved (many thanks to hchiper for helping me) but unfortunately I still haven't figured out how to get it to work right. I went digging and found some things about touchpad calibration matricies and such and have been expiramenting with it trying to figure it out but haven't yet. Any help with it would be appreciated. For the future, I think it would save at least a few people from having this same issue if there were some sort of touch screen calibration tool that worked similarly to how you set your screen size for certain things like various videogames where it has the frame that you drag out to the size you need.

With Much Appreciation,

You can install xinput-calibrator by searching in Synaptic and install it. It will help you calibrate your touchscreen. I hacve never used it so cant attest to its ease of use but I have seen others use it with success.

I believe that is what hchiper had told me to do a while back and I was unable to get it to work. Something weird with my computer wouldn't let it access stuff. Haven't figured out what the issue is yet.

Youre running older hardware so theres no telling how successful you will be with various apps. Maybe doing an extensive search online about your hardware and seeing if anyone else has had any success with a particular app.

that's a good idea. I've done lots of research but havent looked into anything about the specific hardware

Ill post back if I spot anything as Im a technogeezer and have done most of my pc tech work in older hardware.

Im surprised you had issues with xinput-calibrator as its an older program that should be compatible. I remember it being used by many back in the 2000s.

Did some research and it appears many have the same problem as you do with this laptop. No real fixes have shown up so far and again, sometimes it can be a hardware issue that isnt supported properly by drivers, thus calibration tools simply dont work.

I decided to try to install the x11 touchscreen calibrator again because I couldn't remember what exactly had stoped me last time and found that when I put (apt-get install x11-touchscreen-calibrator) into the terminal it omes back with "E: Could not open lock file /var/lib/dpkg/lock-frontent - open (13: Permission denied)" and "E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), are you root?". I recognize the lib from looking at the libinput stuff that is built into the OS and has something to do with touchpad, touchscreen, and tablet screen calibration but at some point I stoped looking at it and forgot how I got where I was. I might try to find my way back there and look into it if I can't find a way to make the x11 touchscreen calibrator work.

I figured it out. I had to use the terminal in superuser mode.

Youve gotta be root for it to work.

I see you figured it out,

I think there is more to it than just installing it but everything in the github page is like a foreign language to me. I know it has something to do with a matrix but all I know about matricies is what I learned about in my high school algebra 2 class last year and I don't remember much of it.

LOL!! I remember very little of those days. There may be a how to for the app online. Maybe try the Debian wiki, https://wiki.debian.org

OldTechLover · Yesterday 05:41

I looked and can't find anything but I'm also not very savvy with the Debian wiki so I could be searching wrong. From what I can tell from the x11-touchscreen-calibrator github, it seems that it is supposed to just be a background system that works on its own. I might try changing my screen resolution and then changing it back to see if it does anything because I saw something about that in the github.

OldTechLover · Yesterday 05:49

Messing with the resolution didn't change anything. I'm not sure what to do from here.

I'm going to go ahead and call it a night, I'm still in school so I'll just have to pick this up again sometime later. Tomorrow afternoon/evening maybe.
