drivers/video/console/vgacon.c

And not documented anywhere. No mention of it in kernel-parameters.txt for example.

Do you think GNOME should be responsible for it? I can accept that the configuration you want for GNOME may not be the configuration you want for something else but it would be nice to have some common interface for handling this.

There is a common interface, and GNOME's display properties applet recently grew a button which applies the current GNOME configuration as the system-wide default.

When i used nomodeset option it did not help me much. nouveau.modeset=0 or radeon.modeset=0 helped however. Where is the nomodeset option evaluated?

I don't actually remember, off the top of my head. I found it once but forgot now. I've always assumed it's universal, but I suppose it might actually be a Fedora-ism.

I would love to see Windows 7 like Multi Monitor support on Ubuntu. You set it up once and it will remember the config, unplug the HDMI it will automatically return to the previous configuration.

It might not be very easy to do or they might not have enough time to do it, but that should be the goal.

That's already supported. The drm will send an event to userspace when a monitor is plugged or unplugged and the ddx will react appropriately.

"Back when the open-source drivers relied on user-space mode-setting, affected users could use a variety of options within the xorg.conf to override values and handle quirks within the server. However, with kernel mode-setting that support is out the window."

You can still use custom configurations in your xorg.conf. That hasn't changed.

gnome mostly takes care of all this

gnome mostly takes care of all this, at least in Fedora we've pretty much got,

auto-detect of digital monitors, and EDID capable analog monitors,
monitor switch key will work through a list of configuratons
saved configurations list
video= on command line for basic EDID override + xorg.conf for X overrides,

when no monitors are plugged in we'll setup a 1024x768, and even start X here and when you hotplug something gdm should pick it up.

Though of course patches from the Ubuntu guys are always welcome, though I'm guessing they'll forget to actually discuss the issues upstream first, hack up a pile of shit and then blame us for not taking it.

That's mostly implemented in the drivers AFAIK. In theory fglrx should do that, although I haven't actually tried.

My mom's system has FGLRX installed, I should try it once. My laptop with crappy Intel GPU doesn't do that on Linux, but handles multi monitors like a dream under Win7... what a shame
