Bug#225435: xserver-xfree86: Incorrectly detected DPI info






What version is display size detection available?

In that case, this bug should be a wishlist to document that the radeon
driver doesn't
currently support display size detection - or backport detection to
whichever version of
the X server that ends up in sarge.

This isn't strictly a bug but a missing feature; the radeon driver in
4.2.1 doesn't detect the display size at all (this has been added in the
meantime, but I'm not sure it was in 4.3.0 already), 75 DPI is the X
server's default value. You can override it with the -dpi command line
switch or the DisplaySize directive in the Monitor section.
