Great idea, Anton! Handy for the shit-sites that make firefox spin violently even when it's not visible!

darcs patch: Add Stoppable layout for power saving
by Anton Vorontsov 28 Aug '14

28 Aug '14

It seems that my last email got silently eaten by spam filters. It's been a whole day, so let's try it again with a different smtp... 1 patch for repository http://code.haskell.org/XMonadContrib: Wed Aug 27 15:02:19 PDT 2014 Anton Vorontsov <anton(a)enomsg.org> * Add Stoppable layout for power saving This module implements a special kind of layout modifier, which when applied to a layout, causes xmonad to stop all non-visible processes. In a way, this is a sledge-hammer for applications that drain power. For example, given a web browser on a stoppable workspace, as soon as the workspace is hidden the web browser will be stopped. The stoppable modifier prepends a mark (by default equals to "Stoppable") to the layout description (alternatively, you can choose your own mark and use it with 'Stoppable' constructor). The stoppable layout (identified by a mark) spans to multiple workspaces, letting you to create groups of stoppable workspaces that only stop processes when none of the workspaces are visible, and conversely, unfreezing all processes even if one of the stoppable workspaces are visible. To stop the process we use signals, which works for most cases. For processes that tinker with signal handling (debuggers), another (Linux-centric) approach may be used.

Per-workspace Application Instances
by Chris Bell 25 Aug '14

25 Aug '14

Hi all, I started using xmonad last week, and encountered very few problems during configuration and use. It's nearly perfect for how I work. But I've run into a bothersome issue. There are times when I need to have dozens of PDFs readily available. Since I started using xmonad, I switched to qpdfview for its tabbed interface. Whenever I open a PDF from a file manager (xfe), qpdfview is called with the --unique option, so that all new windows open as tabs in the main window. The problem is that, if I want to then open a PDF on a different workspace, I either need to create a new instance of qpdfview, or use a different PDF viewer. A minor inconvenience, to be sure. But then I realized that qpdfview has a --instance <name> option, which I imagine could be used with xmonad's workspace identifiers. So, any instance started in workspace 3 would be named 'd3', and qpdfview would be called with '--unique --instance d3'. The problem is, I don't know where to start with this. My idea was to use environment variables to identify the current workspace, but I'm not sure how to. Any suggestions/ideas are greatly appreciated! Regards, Chris

Dim unfocused windows
by Ruslan Kiianchuk 17 Aug '14

Hello. So there is XMonad.Hooks.FadeWindows <http://xmonad.org/xmonad-docs/xmonad-contrib/XMonad-Hooks-FadeWindows.html> module that allows to make unfocused windows slightly transparent. But is it possible to just dim unfocused windows without changing their opacity (the way fadeing option does this for URXVT?). Thanks. -- Sincerely, Ruslan Kiianchuk.

Bug? garbage screen when switching virtual workspaces.
by Klaas van Schelven 12 Aug '14

12 Aug '14

I suppose I should start with a rant on how XMonad sucks to get everyone's attention. However, truth is I've been enjoying xmonad for some c. 5 years now, without any problems whatsoever. However: I've recently upgraded my Ubuntu from 10.04 to 14.04. Xmonad appeared to work after changing the syntax of dmenu_run and recompiling. However, sometimes when switching workspaces, I end up with with some garbage window with the following properties: * slightly offset to the bottom & right from the normal location (slightly means: a couple of pixels) * the area usually contains the contents of the window that was displaying right before making the switch (but as I set, slightly offset to the right & bottom) * usually the window is killable using my standard kill-key-combo. * It appears (though I'm not sure) that google-chrome if often involved in this. One observed behavior: after killing the "ghost window" everything seemed to work fine again, except that chrome was gone. Tentative conclusion: the ghost window was in fact chrome. * My "unfloat" modifier (Mod-T) doesn't change anything When observing the above, I just run windows full screen and use various workspaces for the various windows. * A behavior that appears related: in a few cases I did not manage to get rid of the ghost window. In those cases I got some kind of mosaic inside the full-screen chrome window, comprised of ca. 5 times 5 smaller, mirrored rectangles which contained part of chrome. I'll try to make a screenshot next time this happens. I'm sorry if the problem description is somewhat vague, and/or if I'm not using the correct terminology. As I said, I've set up XMonad years ago, and haven't changed a thing since so I'm somewhat lost for the right words at times (the correct terminology is in my fingers) Any pointers to debugging this problem or requests for specifc configs/logs are welcome. regards, Klaas

xmonad hides xfce4-panel
by Damian Philipp 07 Aug '14

07 Aug '14

Hello xmonad experts, I am trying to set up xmonad (0.11 from Ubuntu repository) as a WM for xfce on a fresh install of Lubuntu 14.04. I configured xmonad.hs as instructed on the Wiki page (The file is so short, I included it inline at the end of this mail). When I start xfce using xfwm4 and then run "xmonad --replace" from a terminal, I practically arrive at my dream desktop. However, when I configure xfce to autostart xmonad, I can briefly see the xfce4 panel flash up and then immediately disappear. xmonad just leaves an empty space where the panel is supposed to be. mod-b toggles the empty space but does not show the panel. The default configuraiton of Lubuntu is to have a single panel at the top of the screen. I can revive the panel by briefly running xfwm4: $ killall xmonad-x86_64-linux $ xfwm4 $ xmonad --replace But that is not really a permanent solution. I looked through the archives, but all I cloud find was posts relating to the interaction of the panel workspace indicator and xmonad workspaces, nothing about the panel going AWOL. What do I have to do to make both the panel show up and run xmonad as my default WM to xfce? Regards, Damian Philipp My xmonad.hs: > import XMonad > import XMonad.Config.Xfce > > main = xmonad xfceConfig > { modMask = mod4Mask > , terminal = "xfce4-terminal" }

Issue 348 in xmonad: Encoding task force
by codesite-noreply＠google.com 05 Aug '14

05 Aug '14

Status: New Owner: ---- Labels: Type-Enhancement New issue 348 by SpencerJanssen: Encoding task force http://code.google.com/p/xmonad/issues/detail?id=348 xmonad is sloppy about strings and encoding. We should go through all of xmonad and make sure all code follows these guidelines: * All String ([Char]) values should be lists of Unicode code points, and should NOT be in UTF-8 or any other encoded form. * All input that creates String values should decoded from bytes in whatever encoding to a lists of code points (this means System.IO and proper locale settings in GHC 6.12, System.IO.UTF8 in older) * All output that takes String values should encode the code points to bytes in whatever encoding (again System.IO in 6.12, utf8-string otherwise) * All non-string data (lists of bytes, encoded strings, etc.) should be stored at types other than [Char] If anybody wants to spearhead this, feel free to come forward. Alternatively we could have maintainers self-certify their modules? -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
