X Resolution - DPI


I've set my Gnome's and X resolution to 96x96 DPI. I set the Gnome resolution through the control panel. For X, I've modified /usr/X11/bin/startx and added -dpi 96 to the server args. I've also edited xorg.conf (Display Size) to match the desired DPI (I'm using a 1280x800 screen size, so I set the number to DisplaySize 340 210, which gives a 95x96 DPI when I type xdpyinfo | grep resolution).

Everything seems to work fine. But sometimes resolution switches out of this range (it want to 75x92 DPI) after a system hibernation (suspend to disk). If I reboot, everything gets back to normal.

Any idea how to make sure the DPI remains always at 96. I'm using Suse 10 w/ Gnome.

Edit your xorg.conf so DisplaySize is included and matches the width and height of your display, as measured in mm

Section "Monitor"
  DisplaySize  406 305
  HorizSync    28-115
  Identifier   "Monitor[0]"
  ModelName    "ViewSonic"
  Option       "DPMS"
  VendorName   "P815"
  VertRefresh  50-160
  UseModes     "Modes[0]"
