Zaphod-mode xorg configuration
Description of problem:
I recently upgraded from Fedora 7 to Fedora 10. In F7 I was able to run my graphics card in zaphod mode, where I have two monitors attached (the built-in LCD and an external monitor) and each one is an independent screen. See the attached xorg.conf that implemented that functionality.
Now with the upgrade to F10 I can't reproduce this functionality, and if I attempt to use xrandr gnome moves my panel/desktop over to the external monitor, which is definitely not what I want.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Attempt to use the attached xorg.conf which no longer works for me
2. (X fails to start)
I can only get a single display.
I would like my zaphod mode again. I need to have two separate monitors that act as separate screens. Windows supports this mode just fine, and F7 supported it as well.
Same problem here. Really hope to have this functionality back.
Is Fedora 11 or Fedora 12 Snap3 any better in this regard?
I'm still on F10; haven't been able to upgrade to F11 yet (mostly due to lack of time). I plan to do the update within 3-4 weeks so I can let you know then if F11 is any better. Is there any reason to expect that the i810 driver regained zaphod mode capabilities?
If I understand what zaphod mode is (that is, extended desktop over two independant displays), then yes. It works just fine on my 965GM laptop.
Well, I have a 945GM.. And the important part is two *independent* displays, so the LCD is :0.0 and the external VGA is :0.1.
I can get a single screen over two monitors right now using xrandr, but that's not zaphod mode. E.g., search for zaphod on http://www.thinkwiki.org/wiki/Xorg_RandR_1.2
I checked, this was removed upstream, and it likely won't get back. If it gets back, Fedora will pick it up, but, for now, we can't do much here.
Unfortunately, I have to close this as WONTFIX. I suggest reporting this upstream, even though zaphod mode was removed on purpose.
