These patches, for the etch-targeted X.Org server, improve dpi handling in
several ways.
The first, fallback_dpi.patch, is a new one-line patch that changes the
xserver's final fallback dpi value from 75 to 100. I've written extensively
(to this bug report) on why this is a very important and quite safe change
that would be great to have in the X.Org packages. In summary, since a
default fallback value will always be required, we should make it a good
one. This has ramifications for the choosing of default font sizes (in KDE,
for instance).
The other two items, 905_debian_xdm.diff.diff and xserverrc.diff, are diffs
to existing Debian patches and files. They remove the forcing of 100 dpi on
startup, when using startx or xdm. With the pending debconf reforms, and
the near-ubiquity of DDC, it no longer makes sense to force a specific dpi
value on startup as the default behaviour. In conjunction with
fallback_dpi.patch, users for whom dpi auto-calculation fails will notice
no difference, since X would in this case fall back to 100 dpi anyway. I've
made more general arguments about dpi handling in my previous posts to
#237877.
I'm putting forth these diffs while the X.Org packages are young and
experimental, since this is the perfect time to try these sorts of changes.
I hope you'll apply them.
Thanks,
Christopher Martin
