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?

Power Management
by Eyal Erez 24 Jan '12

24 Jan '12

Hi, I'm using xmonad 0.10 with Ubuntu 11.10. I've switched to using SLiM and starting xmonad from my .xsession file. The problem is that I can't get power management to work. Meaning, that when I close my laptop lid, I would like the laptop to suspend, but not if it is plugged in. I would also like to have a command (or key) to suspend and hibernate my laptop. In previous versions I would use the gnome-power-manager. However, that has seemed to disappear from the latest version of Ubuntu. Is there some way to get this back or some other power manager I need to use?

NamedScratchpad use case patch
by Nicolas Dudebout 23 Jan '12

23 Jan '12

Hi, This is a patch to make easier use of NamedScratchpad with the DynamicLog pretty printing capabilities. It took me a little while to figure out why the examples given in IndependentScreens were not working when using NamedScratchpad. I knew I had to use namedScratchpadFilterOutWorkspace but it was not obvious how to d'o so. Hopefully this patch helps. Regards, Nicolas

darcs patch: This patch exposes the root window Event... (and 1 more)
by Jochen Keil 23 Jan '12

23 Jan '12

Hello, attached you'll find two patches which the EventMasks for the root and client windows in XConfig. The intention is to enable people to write hooks (or in general modules) which make use of e.g. keyPress/keyRelease Events. I've written some hooks/modules myself which rely on some non-default Events and it works well so far. Since the patches themselves do not change the default behaviour of xmonad nor cause any harm, I'd like to request that they get applied. :) Many thanks in advance and best wishes, Jochen 2 patches for repository http://code.haskell.org/xmonad: Mon Jan 23 11:07:25 CET 2012 Jochen Keil <jrk(a)sternenrei.ch> * This patch exposes the root window EventMask to XConfig This is helpful for writing Hooks which should act on certain Events as for example keyPress or keyRelease.

Logout, Shutdown, Restart.
by Eyal Erez 23 Jan '12

23 Jan '12

Hi, I'm using xmonad 0.10 with Ubuntu 11.10. I've switched to using SLiM and starting xmonad from my .xsession file. Before switching to using .xsession to start xmonad, I used it in conjunction with Gnome, and starting it from .gnomerc. This was slow, and did not enable me to use the latest version of xmonad. However, it had the side benefit of being able to logout gracefully and being able to shutdown/restart directly from within the session without needing to put in a sudo or root password. What I mean by "graceful logout" is that applications that are currently running do not think that the machine died unexpectedly. The most prominent example of that is Firefox and Chrome. If they are running while I hit M-S-q (which runs: "io (exitWith ExitSuccess)"), next time I log in they show me the "I crashed last time, do you want to restore?" message. Currently to shut down my machine, I need to log out, and then shutdown/restart using the login manager, which is annoying. Both this and logout used to work from gnome-do's session management commands. Which I'm guessing is intertwined with Gnome, that I am no longer using. What is the best way to logout, shutdown, and restart from with xmonad?

Problem with anti-aliased fonts in Java/Swing applications
by Christophe Garion 22 Jan '12

22 Jan '12

Hello, I have a problem with xmonad under Debian with no particular config (no Config.Gnome etc.): in every Swing application, fonts are not anti-aliased, which is ugly. If I add the -Dawt.useSystemAAFontSettings=on option when I start a jvm, fonts are anti-aliased. There is no global property file in Oracle jdk to configure this (notice that the problem is the same for openjdk). I can use the _JAVA_OPTIONS environment variable to set this option, but it adds comments in the console every time I launch a java application, which I do not want. There is no problem with GTK applications. If I start a gnome-session from xmonad, fonts in swing applications are correctly anti-aliased. Is there a way to correct this problem? Sorry if an answer has already been provided, but I did not find any searching the web and Xmonad website.

testing xmonad-0.10 for Fedora 16
by Jens Petersen 19 Jan '12

19 Jan '12

Hi, I just wanted to give Fedora users a headsup that xmonad-0.10 is available in the F16 updates-testing repository. https://admin.fedoraproject.org/updates/FEDORA-2012-0158/xmonad-0.10 It has been working well for me now for a while and as you know there are a lot of cool new features and improvements in 0.10, so if you want to help test it before the packages go stable that would be helpful. If I don't hear of any problems I plan to push the packages to stable updates early next week. Thank you very much for 0.10! Jens
