Delays in focus update...
by Allen S. Rout 08 Feb '12

08 Feb '12

I'm running xmonad now on a 4-monitor setup which is slowly approaching perfect-for-me. Yay, and thanks! But I've noticed a certain lack of responsiveness when I make sweeping motions with the mouse, and I've now done a bit of an experiment that seems to narrow it down. To observe this behavior: + open up a lot of shells. Mod-shift-enter 15 or 20 times on an empty workspace will do. + Pick a side of the screen which is an edge, not adjacent to another screen + Move your mouse to that screen, on the -opposite- side from the edge. + Swiftly move your mouse to the edge, like _fast_. 10th of a second or so. You're crossing many terminals. + Watch the successive terminals momentarily get focus; count the time (seconds if you go nuts on the count) it takes for focus to get where your mouse is. .... So it seems it takes constant, substantial subsecond time between window X gets focus, and when xmonad is willing to consider that it might have lost it. Is there some timing loop in there? Or is there something fundamental and X-y happening that limits this? In other WMs, I'm accustomed to focus shifting nearly instantaneously, but I might be missing something. - Allen S. Rout

Status: New Owner: ---- New issue 493 by argu...(a)gmail.com: spawnPipe opens another instance of the applicatioon http://code.google.com/p/xmonad/issues/detail?id=493 What steps will reproduce the problem? 1. Have a spawnPipe on xmonad.hs 2. Hit Mod+Q 3. See a duplicate xmobar running. What is the expected output? What do you see instead? When pressing Mod+Q it should kill my xmobar instance and open another one. When pressing Mod+Q it start another xmobar instance. What version of the product are you using? On what operating system? xmonad-darcs 20111213-1 3.2.2-1-ARCH Are you using an xmonad.hs? Please attach it and the output of "xmonad --recompile". No output on "xmonad --recompile" Please provide any additional information below. Attachments: xmonad.hs 14.1 KB

Issue 450 in xmonad: ManageDocks should check for multi window types in _NET_WM_WINDOW_TYPE
by codesite-noreply＠google.com 07 Feb '12

07 Feb '12

Status: New Owner: ---- New issue 450 by icarnales: ManageDocks should check for multi window types in _NET_WM_WINDOW_TYPE http://code.google.com/p/xmonad/issues/detail?id=450 According to the spec: _NET_WM_WINDOW_TYPE _NET_WM_WINDOW_TYPE, ATOM[]/32 This SHOULD be set by the Client before mapping to a list of atoms indicating the functional type of the window. This property SHOULD be used by the window manager in determining the decoration, stacking position and other behavior of the window. The Client SHOULD specify window types in order of preference (the first being most preferable) but MUST include at least one of the basic window type atoms from the list below. This is to allow for extension of the list of types whilst providing default behavior for Window Managers that do not recognize the extensions. http://standards.freedesktop.org/wm-spec/1.3/ar01s05.html What steps will reproduce the problem? 1. Launch a program with multiple window types like DOCK and NORMAL (tested with unity-2d panel and launcher) What is the expected output? What do you see instead? The window should be ignored and a gap must be created to accommodate it. Instead the window is treated normally. What version of the product are you using? On what operating system? 0.9 Are you using an xmonad.hs? Please attach it and the output of "xmonad --recompile". Any config with ManageDocks (tested with desktopConfig and manual ManageDocks) will do. Please provide any additional information below. I think checkDock function should be in a more generic place like Hooks/ManageHelpers that are currently using the isInProperty function to check for property values.

Learning how to do proper keybindings (and a little bit about xmobar)
by Thomas Løcke 06 Feb '12

06 Feb '12

Hey all, The other day I got my new Thinkpad T420 laptop, and I decided that it was time to put some pressure on my 40 year old brain. I've used KDE on Slackware for what feels like an eternity, so I feel comfortable and at home with KDE. This is both good and bad. Good because I know my way around KDE, bad because over the years I've sorta become a bit of a mouse-junkie (Ack!). So naturally I had to find something completely different: Enter xmonad. I've been fascinated with Haskell for a while now, but never really managed to get started with it. I'm guessing xmonad would be as good a place to start as any. Its been a rocky start for me, I must admit. The whole functional paradigm is both mesmerizing and scary. My first real stumble block has been how to do proper keybindings in xmonad.sh, specifically to be able to adjust the volume using the T420 volume buttons. This is what I've currently got: ---------- import XMonad import XMonad.Actions.CycleWS import XMonad.Hooks.DynamicLog import XMonad.Hooks.ManageDocks import XMonad.Util.EZConfig import XMonad.Util.Run(spawnPipe) import System.IO myLogHook dest = dynamicLogWithPP defaultPP { ppOutput = hPutStrLn dest ,ppVisible = wrap "(" ")" } myKeys = [ ("M-b", sendMessage ToggleStruts ) , ("M-<Right>", nextWS) , ("M-<Left>", prevWS) , ("M-p", spawn "gmrun") , ("M-r", spawn "xmonad --restart") , ("M-g", spawn "google-chrome") , ("M-f", spawn "firefox") , ("M-s", spawn "sudo /usr/sbin/pm-suspend") , ("C-M-h", spawn "sudo /usr/sbin/pm-hibernate") , ("C-M-r", spawn "sudo /sbin/shutdown -r now") , ("C-M-s", spawn "sudo /sbin/shutdown -h now") ] -- This is where it all goes haywire! I found these online, but with no direction on how -- to add them to myKeys. -- volKeys = \c -> mkKeymap c $ -- [ ("<XF86AudioRaiseVolume>", spawn "amixer -c 0 set Master 1+ unmute") -- , ("<XF86AudioLowerVolume>", spawn "amixer -c 0 set Master 1-") -- ] main = do xmproc <- spawnPipe "/usr/bin/xmobar /home/thomas/.xmobarrc" xmonad $ defaultConfig { manageHook = manageDocks <+> manageHook defaultConfig , layoutHook = avoidStruts $ layoutHook defaultConfig , terminal = "urxvt" , focusFollowsMouse = False , logHook = myLogHook xmproc , modMask = mod4Mask -- Rebind Mod to the Windows key } `additionalKeysP` myKeys ---------- The commented block below myKeys is where everything falls apart for me. I cannot for the life of me figure out how to add those two keys to myKeys. Any and all advice is more than welcome! Oh, and one final question: I've chosen xmobar as my status bar and so far I'm loving the slimness completely, but I've noticed that most people seem to be using dzen - is dzen considered the "better" choice? I just want something simple that tells me what workspace I'm on, has a small tray for wicd and some basic cpu/mem/battery info. xmobar does all these things (with a minor glitch in the battery department, but that's for another post), but I'd rather not bet on something that isn't being broadly used by the xmonad community. So, is it OK for me to stick with xmobar? :o) Thomas Løcke

Toggle window decoration
by Norbert Zeh 05 Feb '12

05 Feb '12

Hi folks, I'm currently experimenting with using window decorations (NoFrillsDecoration at this point). While I normally want decorations on my windows, there are situations where I would like to remove the decoration from individual windows and latter restore the decoration. Is there already a layout modifier or other mechanism that does this? If there isn't, that's no biggie because I have an idea of how to implement this using a layout modifier that stores undecorated windows using ExtensibleState, but I'd hate to implement it only to find out that this functionality is already there.

Debugging X events
by Jacek Generowicz 31 Jan '12

31 Jan '12

Hello, I've got a rich set of keybindings in my XMonad configuration, which includes multiple-modifier combinations such as M-C-S-. It all works beautifully on my main machine, but there are problems when running the same configuration on a netbook. I've used xev to analyse the problem and made the following observations: + M-S-<any normal key> works the first time, but SHIFT must be released (and may be pressed again) if <any normal key> is to be detected again. + with M-C-S- held down, <any normal key> is not detected at all, though it you keep pressing it repeatedly it will eventually be deteted after some seemingly random number of presses. Any ideas how to go about trying to understand why this is happening and how to fix it? Thanks.

Using Xmonad as your IDE
by Amy de Buitléir 30 Jan '12

30 Jan '12

I've been using Xmonad for years, and have it customised so that it perfectly suits the way I work. So I hate using most IDEs because they have their own idea of how the edit panes, etc., should be laid out. And I often want multiple terminal windows associated with a project, which most IDEs don't support. Finally I hacked together my own minimal "IDE" in the form of a shell script. I've been using it for 6 months now, and I find it very convenient. To give you an idea how I use it, I associate each project with a different Xmonad desktop. One keystroke invokes the editor. If the current selection is a filename, it will be opened. Otherwise, it prompts me for a file to edit using dmenu (so I usually only have to type a couple of characters to find the file I'm interested in, no matter where it's located in the directory structure). The selection can include line and column information, e.g., "MyProg.hs:8:15:"; the cursor will be set to that location. You might be interested in trying my script if: 1. You want an ultra-lightweight IDE. 2. You use an Xwindow manager that automatically lays out your applications. (I use Xmonad, but you should be able to use wIDE with any Xwindow manager.) 3. You want to edit files using the editor and terminal of your choice. 4. You don't need an IDE to find function, variable and class definitions for you. (I might add ctags support late, but for now, wIDE is probably best suited for one-person projects.) 5. You're familiar with Unix shell scripts. (wIDE is a small shell script, so it's easy to customise and extend.) The current version is available at http://code.google.com/p/wide/ . Happy hacking!

Windows Extending to Both Monitors in a Dual Monitor Setup
by Eyal Erez 29 Jan '12

29 Jan '12

Hi, I've been using xmonad for some time, and I've never seen this problem before. I'm using it on my laptop, which I sometimes connect to a projector or to a monitor using a dock. This has always worked fine. However, a few days ago, it suddenly started stretching my windows across both monitors instead of keeping them tiled on one or the other. It's as if xmonad thinks I actually have one really wide monitor instead of two. I'm not sure where to start looking to fix this, since I didn't really change anything significant of late. If anyone can point me in any useful direction, I would really appreciate it. Thank you, -- There are 10 types of people, those who know binary and those who don't.

Automatic switch to external monitor?
by Tom Davis 26 Jan '12

26 Jan '12

Hey all, I have a dock at work where I plop my laptop each day; used to be that as soon as I woke it, it would switch to using the external monitor only and never turn on the laptop screen. Now it turns on both even though the laptop is closed, and it takes me opening it and running my "dock" script (uses xrandr to turn off laptop display and enable external), shutting the laptop (which sleeps it), then waking it again. Quite irritating! Until recently this seemed to be automatic for me, but since switching monitors it isn't. I'm sure there's some way to do this via ACPI or whatever, but I'm not familiar enough with it to know. Basically i need an action for "docked" that will try running "dock on" and see what happens. Any thoughts?
