Comment 21 for bug 3731

One thought would be for purposes of installation to temporarily swap
with one of those other monitors, if the resolution issue is too
problematic. Then after installation is done just re-swap the
monitors, and fix the /etc/X11/xorg.conf file with the Monitor section I
indicated.

I don't think xresprobe is installed by default so after installation
you might need to add it via:

  sudo apt-get install xresprobe

xresprobe does indeed need to get replaced ultimately. Our tentative
plan is to use Xorg's builtin 'xrandr' system for automatic monitor
detection. However, we've not done much testing of it, but it's easy to
test by just moving aside your xorg.conf. I.e.:

  sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.orig

Then restart X and see what happens. If X fails to work properly, then
log into a console window (Ctrl-Alt-F1) and then do:

  sudo mv /etc/X11/xorg.conf.orig /etc/X11/xorg.conf

The times I've experimented with this, it has worked very well, however
I would like to hear from other users if it also works okay for them or
not.

Thanks,
