Window manager support for Big Desktop/TwinView [SOLVED]

Window manager support for Big Desktop/TwinView [SOLVED]
Okay, so I've figured out the dual display options with Linux now. We've got Dual Head, which does dual screens but doesn't allow dragging between them. To solve that, there's Xinerama to combine the screens together, but without hardware acceleration. Finally, ATI and nVidia have released Big Desktop w/PairMode and TwinView, respectively, solving the acceleration problem. However, it seems that this last solution is problematic because window managers can't detect where one screen begins and another ends. In this case, I'm guessing the only way to handle it is to manually indicate to the WM the dimensions of each screen and their orientation. I can't seem to figure this out in IceWM so far. Is there any similar lightweight WM that has support for this? What about the big two (KDE & Gnome)?

what problem do you have with window managers?
Do you want to maximize only on one monitor? works with fvwm, fluxbox, kde, gnome, ... if you enable xinerama support in X (and probably use flag)
I dont know of an option to make the border between the two monitors snappable, but I think this would be doable in fvwm

iirc Beryl has support for this.
I'm too lazy to keep this stupid signature up to date, so here's something more interesting:
My friend Hetdegon can draw if you ask me.
Now using PClinuxOS on my laptop and Gentoo on my desktop and new laptop.

That's exactly what I want, but I am using ATI's Big Desktop mode (so I can get 3d acceleration on both displays) and not Xinerama.fangorn wrote:Do you want to maximize only on one monitor? works with fvwm, fluxbox, kde, gnome, ... if you enable xinerama support in X (and probably use flag)
Thanks, I'll look into Beryl.sonicbhoc wrote:iirc Beryl has support for this.

Sure thing. This is my config for a Big Desktop setup with my primary 1680x1050 display on the right and the secondary 1280x1024 display on the left. Note that after loading X I need to use xrandr to switch to the appropriate dimensions.
