this is the first time I'm starting a thread here myself, because so far I couldn't find answers to my questions elsewhere. Actually, they're very specific and, it seems, unusual.
I'm using a dual-monitor setup with Ubuntu 10.10 ("maverick") and the standard GNOME desktop. All installed packages are up to date. I configured the two monitors side by side, so that they yield a very wide desktop.
One monitor is a 19"/1280x1024, which I consider the "primary" screen.
The other is a 20"/1600x1200 used for special work.
My graphics adapter is a RADEON 9200 PCI with VGA and DVI driven by the open-source RADEON driver supplied with Ubuntu (even though I don't think that matters for my concern).
However, I'd like to operate the system with only the primary monitor powered up, and switch the other on only when I need it. But when I boot the system with only the primary monitor turned on, X will detect only this one monitor, and the desktop will not extend to the secondary monitor when I switch it on.
So here's my bunch of questions:
- Can I disable auto-detection of monitors at startup and instead configure the system to always assume the presence of the secondary monitor?
- How can I make the window manager (metacity) always open new windows on the primary monitor, so that I'll have to drag them to the other monitor when I'm using it? I see that this may conflict with applications that memorize and restore their window position and size on their own, but let that be a separate issue.
- If 1. and 2. cannot be answered positively, I'll have to keep booting the system with both monitors powered up. However, for best balance between economy and convenience - is there a way to make only the secondary monitor enter its power-save state? Say, from the console? Likewise, I'll have to wake it up that way. I do not use a screensaver, though.
Thanks in advance for all answers and ideas.
