X11 DPI set too high by Fedora8 and can't change

Many fonts appear too big because for some reason my DPI is set to 120x120, instead of 96x96. Although I can set the DPI lower within XFCE using their own manager the high DPI is still apparent when using Emacs and some other apps.

I've tried editing /etc/X11/xorg.conf like some threads have said but there is no "monitor" section so I tried adding that.

I basically put something like this into my xorg.conf


Section "Monitor"
Identifier "Generic Monitor"
Option "DPMS"
Horizsync 28 - 64
Vertrefresh 43 - 60
DisplaySize 381 238.125
EndSection

But xdpyinfo still reports 120x120 DPI

What am I doing wrong? Even /etc/X11/Xresources has the line
Xft.dpi: 96

Try using something other than the Generic Monitor setting. The DPI has to do with your physical display size as will as the screen resolution setting.

I changed the identifier to "Laptop-LCD" and the problem is still there.


For the monitor I also added
Option "UseEdid" "false"
Option "useEdidDpi" "false"

Then under "screen"
Option UseEdidDpi" "false"
Option "DPI" "96 x 96"

What I meant was save your current xorg.conf file somewhere, then use system-config-display to set a new monitor type. Click the hardware tab, then click the configure button next to monitor type, then click the box to show all available monitors. Then chose the brand that matches your monitor, or any name brand monitor thats the same size as yours.
For sample, when I set mine to Nissei Sangoyu CM1584U (a 15 inch monitor) and I have screen resolution set to 800x600 it shows the DPI at 100x100 in xdpyinfo

I can't find anything that matches my Dell 640m's display on the list of monitors so I chose the next closest thing and picked LCD Panel 1440x900. This is my monitor section now:



Section "Monitor"
Identifier "Monitor0"
ModelName "LCD Panel 1440x900"
HorizSync 31.5 - 56.0
VertRefresh 56.0 - 65.0
Option "dpms"
DisplaySize 381 238.125
EndSection


i tried it both with and without the DisplaySize option and he DPI is still 120x120

Well all I can think of is that you can report fonts too big problem as a bug using Fedora bugzilla and see if they can fix it.
