Floating window with respected size hint (xmonad 0.10)
by Daniel Trstenjak 16 Oct '12

Hi all, I tried it with this minimal xmonad config: main = xmonad $ defaultConfig {manageHook = composeAll [className =? "xclock" --> doFloat]} Is there something missing? Greetings, Daniel

Issue 516 in xmonad: XMonad and xmobar wake up too often and are consuming more battery power
by codesite-noreply＠google.com 16 Oct '12

Status: New Owner: ---- New issue 516 by hpsMo...(a)gmail.com: XMonad and xmobar wake up too often and are consuming more battery power http://code.google.com/p/xmonad/issues/detail?id=516 What steps will reproduce the problem? 1. Start XMonad and/or xmobar 2. Check their wakeup frequency with powertop 3. What is the expected output? What do you see instead? About half year ago when I used XMonad for the first time the wakeup frequency was only 10 times per second, sometimes even less. Now it often gets to 100, especially in idle state. What version of the product are you using? On what operating system? Debian wheezy. XMonad 0.10-4+b2 from debian official repo. Are you using an xmonad.hs? Please attach it and the output of "xmonad --recompile". This issue is reproducible on my laptop with any configuration, including the default empty configuration. Please provide any additional information below. When there's an active X program running (like the chromium browser I'm typing in now), wakeup freq of both xmonad and xmobar are likely to drop to about 40/sec. But as keyboard and mouse become idle the freq rises up again.

Re: [xmonad] Issue 40 in xmonad: Screen focus does not follow the mouse pointer

Comment #10 on issue 40 by hanswc...(a)gmail.com: Screen focus does not follow the mouse pointer http://code.google.com/p/xmonad/issues/detail?id=40 I think I can still reproduce this (or a similar) bug in xmonad 0.10. If I move the mouse cursor to an empty screen, for example, that screen doesn't get focus (launched applications will show up on the previous screen). The workspace focus only changes when entering a window or with keyboard shortcuts. I use xrandr with NVIDIA's proprietary drivers.

How to apply (withWorkspace myXPConfig) to two functions?
by Jeffrey David Johnson 10 Oct '12

10 Oct '12

I'm trying to write a function that asks for a workspace name, then sends the current window there and views it. Like these: carryToNext = shiftTo Next NonEmptyWS >> moveToNext carryToPrev = shiftTo Prev NonEmptyWS >> moveToPrev except with a specific workspace. I've got it almost working, but it asks for the workspace twice: carryToSpecific = withWorkspace myXPConfig (windows . W.shift) >> withWorkspace myXPConfig (windows . W.greedyView) There should be some simple way to combine the two, but I'm not sure how to go about finding it. A few things I've tried: carryToSpecific = withWorkspace myXPConfig ((windows . W.shift) >> (windows . W.greedyView)) carryToSpecific = withWorkspace myXPConfig (windows . (W.shift >> W.greedyView)) carryToSpecific = map (withWorkspace myXPConfig) [(windows . W.shift), (windows . W.greedyView)] carryToSpecific = do ws <- withWorkspace myXPConfig return ws $ windows . W.shift ws $ windows . W.greedyView return () What's the proper way? Thanks Jeff

Focus and shortcuts on some applications
by Robert Sawko 09 Oct '12

09 Oct '12

Dear All, I would like to raise two issues and I hope you don't mind if I address them in two separate e-mails. First, is the focus and shorcuts in some application. For instance a Java application Geogebra. When I run it I seem to have focus on it but no shortcuts work until I actually click on the window. The same happens if I change focus to another window and then come back. No shortcuts until I actually click. The same happens for Scilab. When I run it, I can immediately interact with its terminal, but when I change focus and focus on Scilab again, then I actually need to click on the window to start typing in commands. Is this a problem of Xmonad or my configuration? Is there anything that could be done. This "one-click" will not save me a vast amount of time, but would be great if there was something simple that could be done about it. I will be obliged for advice, Robert -- One of the greatest intellectual achievements of 20th century: http://en.wikipedia.org/wiki/Godel%27s_incompleteness_theorems

Xmonad+dzen2+two monitors
by Robert Sawko 08 Oct '12

08 Oct '12

Hello again, the second little issue that troubles me is how make dzen2 display selected workspaces on my two monitors. The relevant line in my setup is this: myXmonadBar = "dzen2 -x '95' -y '0' -h '30' -w '1900' -ta 'l' -fg '#FFFFFF' -bg '#1B1D1E'" And this is really nice. My current workspace is highlighted and also "active" workspaces i.e. workspaces with applications on them are highlighted. But there is no way to distinguish which workspace is the current workspace on the other monitor. xmobar was putting parenthesis automatically which was really good and helpful. Is there anyway to tell dzen2 how to highlight current workspaces on my separate monitors. Please advise, Robert -- A way to reduce entropy: know everything: http://en.wikipedia.org/wiki/Maxwell%27s_Demon

XMonad.Config.Prime, a monadic config syntax
by Devin Mullins 03 Oct '12

03 Oct '12

Hello, folks. Loooong time no see. I had some free time and spare energy this weekend, and this one had always been curiousing me. A couple things: 1. I `darcs rec`d with --no-test, since Minimize was complaining about a shadowed identifier. 2. This adds new build deps on fclabels and template-haskell. I know y'all are generally fairly conservative on new deps. What do you think? 3. Here's a live copy of the haddock doc: http://twifkak.com/xmonad-junk/XMonad-Config-Prime.html Sun Sep 23 22:57:31 PDT 2012 Devin Mullins <me(a)twifkak.com> * XMonad.Config.Prime, a monadic config syntax This is an attempt at a cleaner and more modular config syntax, a follow up to http://thread.gmane.org/gmane.comp.lang.haskell.xmonad/5398. (Hello, everybody! How have the last four years been?) FAQ: Why fclabels instead of data-lens? Of the two, it was the one that successfully compiled on my ancient Ubuntu Lucid machine when I ran `cabal install`. Ick, template-haskell? Really? Yeah, I know. Unfortunately, it seems that GHC won't let me write: > data L = forall l. L l > g f (L l) = L (f l) so I can't really make a generic Layout transformer. I spent a few minutes heading down the path of parameterized monads and NoImplicitPrelude, but the type-system mind games and the juggling between (Prelude.>>) for IO and (Control.Monad.Parameterized.>>) for state were melting my brain.
