I have my dpi set to 91x91. Is this good for a 19" Monitor set to 1440x900? How can I change the dpi on Debian Squeeze? Thanks...

    Your monitor manual/guide should give the correct DPI to be used. You can also use an online DPI calculator to get the correct DPI for your monitor:

    DPI Calculator / PPI Calculator

    For my own monitor, I use the following option in the "Monitor" section of the /etc/X11/xorg.conf file:

    Code:
        Option         "DPI" "94x94"

    You could try adding the following to a ~/.Xdefaults or ~/.Xresources file, then restart X:

    Code:
    *.dpi:    94
    ...changing the 94 to your desired resolution.

    None of those worked, but I was able to set it in xorg.conf:
    DisplaySize 409.26 255.79 # mm

    I found a article that show how to calculate the DisplaySize:
    25.4 divided by desired dpi x resolution
    25.4/89.37 x 1440=409.26

    24.4 converts from inches to millimeters
    89.37 the dpi for my monitor
    I checked on the dpi converter and mine was set very close already.

    Thanks for help
