Running 14.04.4 LTS with 1600×1200 Eizo monitor connected by VGA input (all it has). ATI Radeon HD5450 graphics card, Nouveau driver.
I am trying to create a base xorg.conf that I can then modify, I switched mode with alt-ctrl-F1 and logged in, then stopped lightdm with
sudo service lightdm stop
All good so far.
However when I try to create an xorg.conf with
sudo X -configure
it says nothing to configure, exiting with error (2).
Don’t see what is wrong?
The nouveau driver is for nvidia graphics not AMD, so it is difficult to know what you really do have as driver for that card, though I suspect it may be the radeon driver.
Show us the VGA section of the output of
lspci -vin terminal.

Kernel driver in use: radeon
I thought that was the Nouveau driver doing all these cards, but maybe not. Either way, still not getting an xorg.conf.
As you will see in that final line, you are using the radeon driver, ie the one that comes with Ubuntu at installation and is open source.
If you go to the Additional Drivers utility in the dash you should find there is a recommended proprietary driver for your card; give it a try.
Thanks, yes, I know. I just made the mistake of assuming that all those open source drivers came under the overall label of Nouveau, which, as you pointed out, they don’t.
However, that doesn’t solve my problem, which is not quite what it might seem. Yes, there is a proprietary driver for this card, but this is merely an experiment before transferring to another (older) system with onboard ATI Radeon graphics for which there is no ATI driver for its current kernel. Hence the need to use the open source driver.
I need to do some things I think I may possibly be able do with xorg.conf (using viewportin, viewportout), but it would help to have a ‘get you going’ xorg.conf for the system to start with, which is what I was after. These things work fine with nVidia based graphics, but I’m not sure if they will with ATI.
So, it is partly to solve a problem, partly a learning process.

I’ve never needed to do anything like that with my Intel graphics, so have no experience to go on but it must be worth a try.
It is probably not a failure to create xorg.conf, but a design feature.
None of the several machines that I use with Nvida, AMD, and Intel graphics have xorg.conf. All machines are running 14.04 or later. I remember a few years ago editing xorg.conf, but I have not done it for awhile now. Admittedly, I do have run-of-the-mill systems and only place modest demands on my graphics chips/cards.
Could it be possible that xorg.conf has been removed as unnecessary, or replaced by something not so easily screwed up?;)
For what it is worth, I have listed the contents of my 10-amdgpu.conf …
~$ cat /usr/share/X11/xorg.conf.d/10-amdgpu.conf
