[Pkg-kde-extras] Bug#405133: messes up the display resolution (i.e. the dpi setting)

[Rogier]

Package: kde-guidance
Version: 0.7.0-1
Severity: normal
Tags: patch


After installation of kde-guidance, and restart of X, all fonts were displayed
*much* larger than before. Changing the X-server resolution did not have any effect.
It appeared that using the default installation settings, guidance insists on
rounding the resolution to 96 or 120 dpi. In my case this means a 28% (!) increase
in font size (from 75dpi to 96dpi).

I have tried finding a way to change this behavior, but displayconfig does not have
an option to configure this. After reading the source, I manually created a file
/etc/kde3/displayconfigrc containing the text 'dpi=xserver'.
(For the benefit of other people reading this report: this file can be created in
any of the paths returned by 'kde-config --path config')

IMHO, kde-guidance's default policy should be to modify nothing, and use the X
server's setting. This also gives best results if the user may start X sessions
on different X servers (with different resolutions...). Consistency is also
improved across applications when some do, and others don't use xrdb's value.

Another reason is that users may install kde-guidance along with a large batch
of other software, or upgrades, and be puzzled as to why their fonts seem to
have changed.  Few may discover kde-guidance causes this, and even less will
discover how to change this, except by removing kde-guidance again...


I propose to change FixXorgDPI in
/usr/share/python-support/kde-guidance/displayconfig-restore.py as follows:
