[Bug 349140] [NEW] invalid lcd dpi calculated

[Dmitriy Geels]

Public bug reported:

Binary package hint: xserver-xorg-video-intel

When I first installed Jaunty alpha 6, xdpyinfo shown correct dpi - 125.
But after updates from 24.03 dpi was set to 96. But Xorg.0.log still shows correct screen size:
dmig at dmig-laptop:~$ grep 965 /var/log/Xorg.0.log
[    0.152247] (--) PCI:*(0 at 0:2:0) Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller rev 3, Mem @ 0xfeb00000/1048576, 0xe0000000/268435456, I/O @ 0x0000ec00/8

[    0.569654] (II) intel(0): clock: 71.1 MHz   Image Size:  261 x 163 mm
[   20.510965] (II) intel(0): GTF timings supported

Image size is correct here. But not in xdpyinfo output:
screen #0:
  dimensions:    1280x800 pixels (339x212 millimeters)
  resolution:    96x96 dots per inch

Looks like, that something forced dpi to 96.
