Bug#238770: In /etc/kde3/kdm/Xservers no -dpi Option is set

[Erik Moeller <moeller@scireview.de>]

I experienced the same problem again after updating to KDE 3.4 on
testing. It turned out that a change in the syntax of the kdmrc file was
the cause: /etc/kde3/kdm/kdmrc now directly specifies the X server
parameters, rather than using the Xservers file to look them up. The
default there is, again, to use no dpi setting (which I find problematic
since figuring out the correct DisplaySize setting in xorg.conf is much
harder for a newbie). Changing ServerArgsLocal to

ServerArgsLocal=-nolisten tcp -dpi 100

solved the problem for me. 

HTH,

Erik
