Running in vmware, when I run "xrandr --dpi 96" it prints an error:
xrandr: Failed to get size of gamma for default output And doesn't appear to change the DPI setting. (I test dpi by running xterm -fa "Courier New" and observing if the font changes size.) I don't understand what the gamma has to do with dpi. On a different laptop with inteldrm, xrandr --dpi 96 has the desired effect. No error, xterm changes font size compared with dpi 72.
