Ubuntu 9.10 Dual Head setup

[Robert Kiwanuka]

Hello all,

This is becoming an increasingly disturbing problem. When I try to set up
dual head  (from System > Preferences > Display) I run into the following
problems:

1. Whatever the change I make, if I select Apply the screen freezes and the
_only_ solution is to power off.

2. The default is to mirror screens but I want One large desktop. There is
seemingly no way to change this default behaviour.

3. I work at on least three different laptops each of them needing to use  a
different second monitor depending on where I take it. For some monitors
after selecting the relevant resolutions, it will freeze but, after
restarting it will be configured as desired. But for some it insists on
mirroring the monitors at boot, which means I cannot use any alternatives!

4. If I start a laptop  _and then_ connect the second head then go to
System> Preferences>Display  to enable it, it _always_ just freezes.
Solution is again powering off, which means any work i was doing before that
is lost!

5. Whenever I connect the second head, the resolution of the primary one is
automatically modified so that windows no longer fit well on it (and this
happens for the secondary one too). In the Display dialog it thus becomes
difficult to select the options (Apply/Close). In my case I have to rely on
the fact that I know what keyboard shortcut to use in this situation, but
what does everyone else do is such cases - I'm assuming that other people
have had this as it has been repeated on all my laptops so far.

6. Sometimes I'm asked if I want to keep the configuration or return to the
previous but sometimes not! Why?

7. I no longer have a good xorg.conf to refer to in order to set what I want
with out the GUI interface!

Any ideas on how to sort any of that out? Does anyone have a working
xorg.conf where they have manually determined the display/monitor/screen
settings. I would rather play with that suffer with the GUI where nothing is
certain.

Regards,

Robert
