Bug#339707: gdm: GDM must not mess with the dpi.

[Simon Budig]

Package: gdm
Version: 2.8.0.6-2
Followup-For: Bug #339707


Even if gnome messes around with the DPI (wrongly!), this is no reason
to do it in gdm as well. You can change the gnome dpi setting at
runtime, but you cannot do this with the changed gdm setting, since
xdpyinfo will stick to that dpi setting. Applications relying on proper
dpi information are doomed to failed and the user is bound to edit
config files. Heck, even the explicit configuration of the monitor size
in the xorg.conf file gets clobbered.

If you need to work around broken autodetection of the display size from
the x-server, do it by hardcoding a display size for the x-server in the
xorg.conf (DisplaySize keyword in the Monitor section). This is the
place where someone would look for that setting. GDM must not mess with
this.
