Bug#182191: Xserver always sets screens to 100dpi, ignores DisplaySize

[Russell Shaw <rjshaw@iprimus.com.au>]

Package: xbase-clients
Version: 4.2.1-3
Severity: normal

Hi,
I found that DisplaySize in the monitor section of
/etc/X11/XF86Config-4 is always being ignored. This
can be seen with "xdpyinfo" and /var/log/XFree86.0.log
to be 100dpi.

Section "Monitor"
          Identifier      "Philips"
          VendorName      "Philips"
          ModelName       "C20 (CM0500)"
          HorizSync       31.5,35.2,37.8,48,56,64
          DisplaySize     312 234
          VertRefresh     50-90
          Option          "DPMS"
          Gamma           2.4 2.5 2.6
EndSection

I found it's an xbase-clients installation bug. It makes the windows,
fonts, and icons in X the wrong size.

If you look in /var/log/XFree86.0.log or xdpyinfo, you'll find
that DisplaySize is ignored and you get a physical screen size different
to your real screen. It gets set to 100dpi when mine should be around 80dpi.

It means that any assumptions about font and window sizes by
X apps is all wrong. Instead of 1pt being 1/72", it's more like 1/60",
so all the fonts end up bigger than they should. It also means that
changing the resolution from 800x600 to 1024x768 changes the *physical*
screen size, making all the fonts and everything else change size when
they should be constant.

/etc/X11/xinit/xserverrc contains:

    #!/bin/sh
    exec /usr/bin/X11/X -dpi 100 -nolisten tcp

So i changed it to:

    #!/bin/sh
    exec /usr/bin/X11/X -nolisten tcp

which fixes the problem.
