Wanting to do a window-shift in a event handler
by Michael Norrish 03 May '11

03 May '11

My situation is that I'm using Thunderbird and its External Editor plug-in to write mail. When I invoke the external editor, it brings up an emacs window (calling through emacsclient). I have a manage hook that puts emacs windows into a particular workspace, but I don't want e-mail composition emacs windows to go there. I thought I could handle this by looking at an emacs window's WM_NAME in my ManageHook, but unfortunately, it seems at this point that the title is still just "emacs@<myhost>", which is not helpful. It seems that the useful title (which is of the form "<something-or-other>.eml") gets created a little later. So, I thought I would put in a general eventhandler to watch for a property change, and to then do the shift to the appropriate workspace. So, I added handleEventHook = mappend myhandlePropEvent (handleEventHook defaultConfig) to my modifications of the default config. I then have myhandlePropEvent ev = case ev of PropertyEvent {} -> let w = ev_window ev ... Through calls to trace, I can see that I am indeed picking up on the desired event (the change in the window's name), and I have a window (w above) to hand, but I don't know how to do things to it. My cursory examination of the relevant APIs suggested I could do action <- runQuery (doShift "mail") w giving me a handle on an Endo Windowset, but I don't know how to lift that into the X monad (where I have to eventually return $ All True). Can I use the withWindowSet function somehow? Michael

Fresh install on ubuntu, no windows appearing
by Brian Victor 28 Apr '11

28 Apr '11

I'll open by saying this is not the FAQ. I'm pressing mod-shift-enter; that's not the problem. I installed Ubuntu 10.10 under VirtualBox, using all defaults. Then I did apt-get install xmonad, which pulled in xmonad 0.9.1. At this point I tried a few approaches to switch to xmonad, based on http://haskell.org/haskellwiki/index.php?title=Xmonad/Using_xmonad_in_Gnome For the simplest approach, I killed metacity then ran xmonad. Upon running xmonad, all my windows disappeared. I pressed mod-shift-enter a few times; no terminals appeared. I killed xmonad and started metacity again. The original windows reappeared along with the terminal windows I created while xmonad was running. They were in a layout that could only have been created by xmonad. So it's clearly doing something, but I can't see what while it's running. /usr/share/applications/xmonad.desktop and /usr/share/xsessions/xmonad.desktop both exist. I've tried the various gconftool commands on the above page, admittedly in a somewhat cargo-cult manner. When I feel like I've strayed too much from the pristine config, I recreate the user settings. Any ideas on fixing this? -- Brian

XMonad.Actions.DynamicWorkspaces selectWorkspace prompt nitpicking
by Joseph Garvin 28 Apr '11

28 Apr '11

I just discovered the excellent XMonad.Actions.DynamicWorkspaces but have two issues with selectWorkspace: -If I don't type a workspace name and just hit enter, it assumes I want to create an unnamed workspace. I'd prefer it did nothing. It's confusing because you see in your pager you have an extra workspace but there's no extra workspace in the prompt. At first I thought XMonad or my pager was bugged. -selectWorkspace appears to act more like "selectOrAddWorkspace." If you type the name of a workspace that doesn't exist, it creates it. I'd prefer it pick the workspace I would have gotten had I pressed tab to do completion first. The reason is that I'm used to ido mode in emacs, where it autocompletes as you type, so you never have to hit tab. Because selectWorkspace only takes an XPConfig, I don't think there's anyway for me to customize it, without diving into the extension's code. Am I right? Or is there a better way? -Joe G.

Putting PID into window title?
by Joseph Garvin 28 Apr '11

28 Apr '11

I sometimes spawn multiple instances of app that puts important information in the titlebar of its main window, but doesn't put the information in the titlebars of its child windows. When I run two instances of this app on the same desktop, it's difficult to tell which child windows are associated with which main window. If the PID associated with each window were in its titlebar, I could match the child windows and main windows up easily. I have checked that the app in question correctly sets the _NET_WM_PID property, but I don't see anything in Decoration or SimpleDecoration for letting me add my own text. Is there a way to do this? Thanks, -Joe G.

Avoid automatic change of workspace
by Raghavendra D Prabhu 26 Apr '11

26 Apr '11

Hi, I am currently using twinview with xmonad with two physical screens. My issue is, suppose I have workspace 4 on screen 1 and 5 on screen 2 and current screen is 2. At this point, when I switch to workspace 4 (with mod key + workspace# ), it transfers the 4th workspace to current screen and vice-versa, what I want is for it to change to the other screen rather than bringing the workspace from that screen to current screen. Is there any way to change this ? -------------------------- Raghavendra Prabhu GPG Id : D72BE977 Fingerprint: B93F EBCB 8E05 7039 CD3C A4B8 A616 DCA1 D72B E977 www: wnohang.net

Do you happen to have a non-rectangular screen, e.g. two screens of different size? There was a discussion about that on the xmonad mailing list. And maybe someone on the xmonad mailing list can help?

Re: [xmonad] Determining layout based on display properties

I wrote a module to do exactly that. I'm not entirely happy with it (and patches are definitely thoughtfully considered), but it's available at > https://github.com/nwf/xconfig/blob/master/xmonad/lib/XMonad/Layout/SLS.hs Hope that helps. --nwf;

Determining layout based on display properties
by Samir Unni 20 Apr '11

20 Apr '11

Hello, I was wondering if there's a way to change the workspace layout based on the properties of the display (i.e., resolution). I'm trying to use a three column layout when my laptop is using an external monitor, but a two column layout when I'm using the built-in display. This doesn't have to be dynamic - if the workspace layouts are set once when xmonad is launched based on which monitors are in use, that would be fine. Thanks, Samir Unni

Issue 446 in xmonad: Use XMonad.Layout.Minimize in XMonad.Config.Gnome
by codesite-noreply＠google.com 17 Apr '11

Status: Accepted Owner: vogt.a...(a)gmail.com New issue 446 by vogt.a...(a)gmail.com: Use XMonad.Layout.Minimize in XMonad.Config.Gnome http://code.google.com/p/xmonad/issues/detail?id=446 Perhaps some other features used in XMonad.Config.Bluetile could also be added to the config too? At least one user in #xmonad (brianmwaters) expected this to be the case.
