I have an HP laptop with a 1366x768 tactile screen. I need to run some kiosk software which needs a resolution of 800x600, so I set it with xrandr:
xrandr --output eDP-1 --mode 800x600
It looks good, looks like xrandr has added black bars at both sides of the screen to keep the aspect ratio.
The problem arises when I touch the screen. The further I touch from the center of the screen, the more off the cursor is. Looks like when I touch the screen it takes into account the side black bars to calculate where the cursor should be. Say I touch 25% into the physical screen, the cursor is placed 25% into the visible screen, so it does align.
I tried using this link to calibrate the touchscreen, but it makes no difference at all.
