It can be vexing to get the hang of it, but it is certainly doable. The
xorg.conf methodology is a bit tougher to figure out, but can in some cases WRT
the login greeter be more effective. I have TDE working with multiple displays
with Intel, ATI and GeForce gfxchips.

You might want to give arandr a try before continuing with either manual
configuration method. contains a bunch of xorg.conf templates. It
also contains a setup file, which contains nothing but functional one-line
xrandr commands, many of which are for configuring dual displays of various
resolutions with various gfxchips. Note that the fbmm and dpi parameters are
options I use, not required. I use them when forced 96 DPI is unwelcome, which
is normal here.

If none of the above is help enough, when you post back, be sure to show us an
Xorg.0.log, xrandr commands and/or xorg.conf* you tried, and some detail about
what hardware you're working with, 'inxi -c0 -G' at a minimum. What distro?

If you start X using startx you ought to be able to go into settings and set a
longer timeout on or turn off the screen locker.
