Touch Screen Calibration - Transformation matrix & Overscan

Image
0 So - I have a machine running a 7" touchscreen and the touch screen is placed behind a smaller 6" opening, I have used overscan to make the screen align with the opening which worked well. But now my problem is trying to calibrate it with the new size! I have used xinput calibrator - changes nothing. I then realized that I needed to use a transformation matrix for this - so I followed a wiki article on Arch linux - this changed something but not in the right way! The screen resolution is 1024 x 600 Overscan: Left: 60 Right: 60 Top: 60 Bottom: 5 c0 = touch_area_width / total_width c0 = 904 / 1024 c2 = touch_area_height / total_height c2 = 535 / 600 c1 = touch_area_x_offset / total_width c1 = 60 / 1024 c3 = touch_area_y_offset / total_height c3 = 60 / 600 Can you see anything wrong?

Monitoring running processes

0 Specifically, there's an application I want to fix by understanding what happens to it before it freezes and the terminal only tells me the libraries it's loading. But I'd like to use a tool like this for other things too that are mostly network related and don't know how to go about it. I'd like to be able to monitor activity for running processes or applications and processes associated with them. I'd like specific information like what files the process is accessing, the network activity, the status, the number of instances, and similar information. I'd also like to be able to record or log the activity. This seams similar to what I want, but they're windows tools. ps and htop seam a little weak but I haven't used them. I'm running Debian 9.7. ...
