I am booting from Tails using a usb. I can start up the machine fine, but everything looks very small. My resolution is 2880x1800 with a dpi of 220, but it is detected as 2880x1800 with a dpi of 94.
I have tried using xrandr to change the dpi but it fails to cause anything to happen visually.
Additionally, I have tried to just change the resolution to something smaller; using the system tools options in the menu and using xrandr, but both of those result in a black screen.
