KDE/Gnome is irrelevant, the monitor resolution is controlled by X. The proper
way to troubleshoot these issues is to provide us with the output of "xrandr",
and the complete log file /var/log/Xorg.0.log, for both the correct- and wrong-
resolution sessions. It is possible that your monitor is not providing the
correct EDID data, or you have two monitors plugged in at the same time, or
something similar. Please provide the logs and describe your setup (graphics
card, video driver, number of monitors, etc.), and then we should be able to
tell you what is going on and why.
As for the xorg.conf file, it does not exist anymore by default, unless you
create one yourself. The proper path is /etc/X11/xorg.conf . Write the part of
configuration that you need customized (other stuff you can leave to be
autodetected).
HTH, :-)
