Hello List! I don't know if this is the proper place to ask, but I don't know where else I should drop this. I browsed through the FAQ on the website and stumbled over a TODO at question 3.20 (http://www.haskell.org/haskellwiki/Xmonad/Frequently_asked_questions#How_ca…) I don't know whether xmonad >=0.8 supports (and uses) UTF-8 as default, but I guess that this could be answered and thus this answer could and should be adjusted ;) So, how is it with xmonad and UTF-8? Greetings from Cologne, Christian.

XMonad Efficiency
by Norbert Zeh 17 Apr '12

17 Apr '12

Hi folks, I must admit that I for now gave up on trying to make the decoration module more efficient. I tried two of the three ideas I had, and they didn't work well at all. My third idea (turning most of the lists in the decoration module into binary trees) is likely to work well, but for now I don't have time to implement it, particularly because it's not one of my main issues I would like to see addressed in xmonad. Related to the above, however, I noticed that even without decoration, fast focus switches drive my CPU usage up, much more so than in other non-tiling window managers. Running top gave me a surprising insight: it's not xmonad but the X server that consumes that many cpu cycles when focus switching. Here's my theory of the source of the issue: every focus change triggers the recomputation of the layout (as it should because some layouts rearrange windows in response to focus changes), and every recomputation of the layout updates the geometry of every window currently visible - that's a lot of work on the X server's side for a simple focus change. (1) Can anybody who is more familiar with the inner workings of xmonad core confirm that this is indeed what's going on? (2) A fairly simple fix for the above would be to cache the geometries of visible windows and tell the X server to update a window only if its geometry has in fact changed. Does anyone on the list have a feel for how hard it would be to add such a caching mechanism to xmonad core? Would it break anything? At this point, I'm simply pondering what can be done about it, as one of the reason's I'm using xmonad is that I want a lightweight desktop environment. (When fast focus changes drive one of my cores to 50%, that's hardly lightweight.) It'll be a while before I would get around to trying to implement the above.

Issue 505 in xmonad: Strip the executable file created during recompilation
by codesite-noreply＠google.com 17 Apr '12

Status: New Owner: ---- New issue 505 by jach...(a)gmail.com: Strip the executable file created during recompilation http://code.google.com/p/xmonad/issues/detail?id=505 What steps will reproduce the problem? 1. recompile xmonad I think it's a good idea to strip the executable file generated during recompilation to make it even more lightweight. My xmonad version is 0.10 I believe the following code is pretty self-explanatory: $ cd $ xmonad --recompile $ ls --size .xmonad/xmonad-x86_64-linux 2552 .xmonad/xmonad-x86_64-linux $ file .xmonad/xmonad-x86_64-linux .xmonad/xmonad-x86_64-linux: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, BuildID[sha1]=0xfec31cee9b5541ce3310171ffa299d0282a5cfb8, not stripped $ strip .xmonad/xmonad-x86_64-linux $ ls --size .xmonad/xmonad-x86_64-linux 1648 .xmonad/xmonad-x86_64-linux $ file .xmonad/xmonad-x86_64-linux .xmonad/xmonad-x86_64-linux: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, BuildID[sha1]=0xfec31cee9b5541ce3310171ffa299d0282a5cfb8, stripped

Issue 504 in xmonad: Suggested modification to XMonad.Actions.WindowsGo.runOrRaiseNext
by codesite-noreply＠google.com 16 Apr '12

Status: New Owner: ---- New issue 504 by dansp...(a)gmail.com: Suggested modification to XMonad.Actions.WindowsGo.runOrRaiseNext http://code.google.com/p/xmonad/issues/detail?id=504 Best explained by an example: Currently: I have 2 instances of chrome running: Chrome1 (runRaiseNext Pidgin) Pidgin (runRaiseNext Chrome) Chrome2 (runRaiseNext Chrome) Chrome1 Proposed Change: I have 2 instances of chrome running: Chrome1 (runRaiseNext Pidgin) Pidgin (runRaiseNext Chrome) Chrome1 (runRaiseNext Chrome) Chrome2 I think the current behavior is not ideal, as it makes it difficult to swap between a particular window of an application and any other window. Very simply put my suggestion is NOT to cycle to the next window if the window we are coming from is not an instance of the window type.

Mail-plugin from xmobar
by 1126 15 Apr '12

15 Apr '12

Hello list! I'm not sure wether this is the right list to ask, but the Xmobar-List itself seems pretty dead to me. At least that's what I figured when browsing through the archives. Anyway, here's my problem: I try to add the mail-plugin to my xmobarrc and it complains: unexpected "s" expecting space or "Run" Here's what my xmobarrc looks like: Config { font = "xft:terminus-8" , bgColor = "#121212" , fgColor = "#ECECEC" , border = TopB , borderColor = "#F0E800" , position = Bottom , lowerOnStart = True , commands = [ Run Com "uname" ["-s", "-r"] "" 0 -- , Run MPD ["-t", "<state> (<lapsed>/<length>) | <artist> - <album> - <track> - <title>"] 10 , Run Mail [("inbox", "~/mail/mailboxes/uni/INBOX")] "mail" ] , sepChar = "%" , alignSep = "}{" , template = " %uname% }{ %mail% " } Any help is appreciated. Thank you :) Greetings from Cologne, Chris

Desktop Environment Integration
by Sean Allen 06 Apr '12

06 Apr '12

No right answer here. Just looking for information/advice about desktop environment integration. I've been using xmonad for about 16 months now and loving it. I currently use it integrated with gnome 2. About the only things I use gnome for are: gtk/desktop theming. easier multiple monitor setup. less x hassles. basically, has a shortcut to getting the basics configured. I'm going to be moving on from that machine soon and I'm trying to decide what to do. xmonad w/ nothing? <-- and handle all of the above issues manually gnome 2? gnome 3? kde? Problems using any of the above? Suggestions based on what I really care about with using gnome for best things to use? Seriously considering just going w/ xmonad but I really do like the little layer of 'not x' that I get with a gnome or kde or xfce etc. Thanks. -Sean-

how to install xmonad for group of users.
by Imam Toufique 04 Apr '12

04 Apr '12

Hi, I have been trying to install xmonad (using cabal) for the past week for a group of users and having some issues with it. When I try to install it for myself it works just fine, but I when I try install it for a group of users, it gives me errors that some packages/modules are missing. I used the following cabal command: >cabal install --prefix=$PREFIX --build-log=/tmp/xmonad.log.3 xmonad (where my prefix is /net/tools/xmonad/0.10 I see the installation there, I can run it myself, but when another user goes about it running it from the same installation, it complains that some packages/modules missing. I noticed that my installation creates $HOME/.ghc directory where all the packages are registered. I think therefore, for another user it can't access my $HOME/.ghc and therefore fails. Is there a way to tell cabal installer to register the packages in the $PREFIX area? I am so new to ghc, I tried figuring it out, but I could not. I think if I can register the packages somewhere in the PREFIX (/net/tools/xmonad/0.10) area, then xmonad running for a different user(s) will be able to access the right packages, and that might fix this issue. thanks in advance.

nedit-nc -tabbed no longer working
by Ben Franksen 04 Apr '12

04 Apr '12

Hi Xmonadists I am a long-time fan of the -- unfortunately no longer maintained -- text editor that goes by the name of 'nedit'. Nedit is built on the Motif toolkit. Nedit can be run in client mode (the executable is named 'nc' in this case, for nedit client, on debian and some other systems called 'nedit-nc') meaning that it attaches to a running instance of nedit. If given the extra switch -tabbed, it will open another tab inside an already open nedit server session. Depending on a configuration setting, it starts a new server if none is found. A few xmonad-versions ago 'nedit-nc -tabbed' suddenly stopped working. Instead of opening the file as a new tab inside the running session, a new window is opened. If no session is already running, I get _two_ windows, one with the file I specified (on the command line) and one with a new file ('untitled'), which is quite annoying, especially in a tiling wm such as xmonad. There is, by the way, only one nedit-server session running, so the client mode works in principle, only the -tabbed mode is broken. This works fine under all other window managers I tried, including those of gnome, kde, xfce, and lxde. I tried anything I could think of to fix possible problems with my configuration but to no avail. I gave up then and went back to using kde when programming. But I am missing xmonad very much and would really like to go back to using it, so I finally decided to report this as a bug. I think the nedit client mode utilizes some X11 feature for communicating between processes over the X11 protocol, but I have no intimate knowledge of X11, so I can't tell for sure. BTW, most linux distributions still offer nedit as a package, if yours does not the latest sources (from 2005) are available from the nedit.org site. I would be extremely happy and thankful if someone finds a solution for this problem so I could again use my favourite window manager *and* my favourite text editor together. BTW, I am currently on a 64 bit amd running debian testing. Cheers Ben
