Excerpts from Ivan Lazar Miljenovic's message of Mon Jan 11 05:34:21 -0700 2010:

I'm doing a presentation using Beamer [1] for LaTeX. It allows using the second screen for notes by basically creating two-screen wide "pages" with the idea of having the entire full screen presentation spread across both screens (and the projector only showing one screen).

Now, this works well for how "traditional" window managers treat multi-head as one big workspace, but obviously doesn't work too well for xmonad. Is there any nice way I can do up a key combo or something (maybe even a ManageHook?) to have it automatically go floating and spread out across both screens (i.e. across the entire visible area)?

There are a couple of hacks that may help here. If your monitors are side by side and the same resolution it's simpler, but I'll assume they differ. Apologies in advance for any arithmetic mistakes in my examples. XMonad.Hooks.ManageHelpers.doRectFloat can use height and width fractions greater than one, so using some silly example screen resolutions you could do something like: * 6x8 leftOf 16x9, screen tops at same y position * Launch beamer on the left workspace import XMonad.Hooks.ManageHelpers doRectFloat (W.RationalRect 0 0 (22/6) 1) <+> doShift "3" You could also set up a keybinding to split your two monitors into two workspaces and another to return them to normal. Beamer mode would give one workspace spanning the monitors but only as tall as the highest monitor, the other workspace would take the remaining space on the taller monitor. import XMonad.Layout.LayoutScreens -- split them layoutScreens 2 (fixedLayout [Rectangle 0 0 22 8, Rectangle 6 8 9 1]) -- back to normal rescreen Hope that helps. Also that PEPM, traveling to it and preparations are all mostly fun and exciting. -- wmw
