Built in laptop touchscreen not properly calibrated

OldTechLover · 2024-10-21 07:47

I've got Q4OS running on a couple old laptops of mine including my old Toughbook CF-30 Mk.3 (which I used to post this) and I'm loving it. I only really have one thing to complain about so far. The built in touchscreen doesn't line up right. I place the stylis on one part of the screen and the cursor goes somewhere nearby but far enough away that it's rather difficult to just work with it. It gets worse as I move the stylis away from the lower center part of the screen. If I place the stylis straight in the center of the screen it lines up with the cursor but I if I place it on the edge of the screen the cursor is a little under an inch (roughly two cm) away from it. In fact the cursor and stylis only align vertically if i place it about 2 inches (about 6 cm) up from the bottom edge of the screen and it becomes misaligned in the other direction of I go lower. It is similar horisontally except it aligns about an inch and a half (3.75 cm) to the right of the center of the screen. If someone who knows more about this than I do could please help me out I would greatly appreciate it as I've looked everywhere and have hardly found anything.

I searched for packages whose name contain "touchscreen" and I discovered so the existence of "x11-touchscreen-calibrator".
I don't know if it can be useful for you...
For some info on it, type $ apt info x11-touchscreen-calibrator

Thankyou for the help. I tried what you said but I can't figure out how to install the software. The github is very confusing as is the homepage and the release files I was able to find were essentially a download of all of the information on the page. I tried it in the terminal as well and it keeps telling me it can't unlock the files.

All you need to do is use Synaptic package manager in Q4OS. Type in x11-touchscreen calibrate or touchscreen and just scroll to the package, Select the package by clicking on the box and click mark for installation. Go to apply ,click and the package will be installed. I checked and its definitely available in Synaptic package manager.

I hadn't seen your response over here crosscourt. I wish I had checked over here prior to going through all the trouble of trying to figure out how to get it to install through the terminal. Oh well, live and learn. Now I just have to test it and such. I'll post later with an update on how it works out.

Im still curious why xinput-calibrator didnt work with your Toughbook.

Before trying to calculate and install a new matrix, it would be interesting to know if the "active" matrix has not already been modified.
Please open a terminal and enter the command
xrandr --verbose > /tmp/xrandr.log
and post the xrandr.log file which is located in the /tmp directory.

Edit:
Interesting to read the description of the --transform option in the xrandr man page.

hchiper, oldtechlover is also posting in a thread in feature requests about this topic. The Panasonic Toughbook of 2007 was a very problematic piece of hardware in regards to the touchscreen with Linux.

@crosscourt Yes, I know, I have seen it before answering this afternoon. I posted my last message here because it is more a response to an issue than to a feature request.
