windows overlap the task bar
by Alain Bertrand 12 May '19

12 May '19

Hello, I have been running xmonad for years on my desktop (Debian 7, then 8 and 9) and I am highly satisfied: this is the only one that prevents me to "try another thing"! On my laptop (ubuntu 18.04), the windows overlap the task bar though I use exactly the same xmonad.hs file as I do on my desktop. Could you help me ? TIA Alain import XMonad import XMonad.Hooks.SetWMName import XMonad.Hooks.ManageDocks import qualified Data.Map as M import Graphics.X11.Xlib import XMonad.Config.Azerty import XMonad.Prompt import XMonad.Prompt.Shell import XMonad.Prompt.XMonad import XMonad.Actions.SpawnOn myStartUpHook :: X () myStartUpHook = do spawnOn "panel" "xfce4-panel" setWMName "LG3D" main=do xmonad azertyConfig { layoutHook=avoidStruts $ layoutHook defaultConfig , manageHook=manageHook defaultConfig <+> manageDocks , modMask = mod4Mask , keys = myKeys <+> keys azertyConfig , startupHook = myStartUpHook } -- main=do -- xmonad { keys = myKeys <+> keys azertyConfig } -- { -- layoutHook=avoidStruts $ layoutHook defaultConfig -- , manageHook=manageHook defaultConfig <+> manageDocks -- , startupHook = setWMName "LG3D" -- } -- -- myKeys conf@(XConfig {XMonad.modMask = modm}) = M.fromList [ ((modm, xK_F12), xmonadPrompt defaultXPConfig) , ((modm, xK_F3 ), shellPrompt defaultXPConfig) ]

Spent a fair bit of time improving my XMonad config, perhaps you'll find something useful
by Michael Sloan 11 Feb '19

11 Feb '19

Hey all, I recently improved my XMonad configuration quite a bit, and figured that some of y'all might also want some of the things I implemented. The repo is: https://github.com/mgsloan/mgsloan-dotfiles The main larger chunks of code is using the rio package for logging and process running. Run processes also get wrapped in `systemd-cat`, which ends up being rather nice because `journalctl` has various structured ways of querying the logs. In particular, on workspace 9 I've got a couple terminals showing the most recent logs, as well as all error messages since boot. I've considered wrapping this up in a package, but only if there's interest in such a thing. There's lots of other stuff too, but most of it's quite a bit more specific to the particulars my setup. I've described the different parts of the config in readme.md in that repo. I hope you find something useful from it! -Michael

New virtual X mouse tool
by Blake Miller 31 Dec '18

31 Dec '18

This is only indirectly related to XMonad... For a while I've been using keynav to avoid reaching for the mouse for those few annoying circumstances which seemingly require a mouse. I did find that keynav sometimes saved me some energy, but I only found it useful for simple clicks. It does not seem useful if you want to click and drag a region, for example. Repeatedly bisecting the screen to narrow in on a point for the cursor is a fine approach and has some advantages, but I found myself wanting something more visceral: a little physics simulation to let me move the mouse around using the keyboard, like a video game. So I put this little utility together, in C++, and I have a keybinding spawn it from xmonad. It was an interesting challenge to make it single-threaded and still simultaneously run the physics loop, poll for X events, and send fake mouse events with XTest. I ended up designing it around channels (as in CSP) using boost::fiber. I hope someone finds it useful or entertaining! I had fun writing it. https://github.com/blak3mill3r/mouser

Changing workspaces on both physical screens
by Christophe Garion 16 Dec '18

16 Dec '18

Hello, I am using xmonad on my Linux laptop and pdfpc (https://pdfpc.github.io/) for presentation. pdfpc uses two windows, one with current slide, next slides, notes etc. and the other one with the presentation only. I usually use workspace 8 on my laptop with the window with notes and workspace 9 on the projector with the presentation window. I sometimes switch workspaces to show code snippets in emacs etc. and I want to be able to quickly restore the "pdfpc" workspaces. I use the following binding: ((modMask .|. shiftMask , xK_p), (do windows (W.view "9"); swapNextScreen; windows (W.view "8"))) which may not be the most elegant solution :) Is there a more "haskell" way to do the same thing? Best, Christophe -- Christophe Garion GPG: 1982 15B2 64AC 3C34 532D BF19 6CD6 246C 62DA 5A7F

Re: [xmonad] Suspend Keybinding Temporarily

Er. What version of ghc? That sounds like either a ghc runtime bug, or a system configuration issue. In particular, xmonad creates no threads itself, so that would be the ghc runtime's IO manager thread.

Suspend Keybinding Temporarily
by Eyal Erez 29 Nov '18

29 Nov '18

Hi, I'm getting some collisions between my xmonad keybindings and an application I'm running (it's a game that is suppose to run full screen but in reality just uses a large window). I was wondering if I could suspend or change some keybindings from a script that I can run before the app launches and then restore later. Is this at all possible?

Can't lock screen with light-locker-command
by Thomas Järvstrand 24 Nov '18

24 Nov '18

Hi! I just moved back to xmonad after having used qtile for a few years and I'm having trouble locking my screen using light-locker-command. When calling "light-locker-command -l" from the command line, I get the this back: "Received error message from the locker: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.ScreenSaver was not provided by any .service files" I'm running Ubuntu's mini.iso, lightdm, and a simple session file that just calls /etc/X11/Xsession. My .xsession only adds "~/.cabal/bin" to the PATH and execs xmonad. xmonad version is 0.15 but I get the same behaviour when installing xmonad via apt and running the package's session. I have tried purging and reinstalling both lightdm and light-locker. The curious thing is that the same lock command works fine if I run qtile from my .xsession instead of xmonad. Any pointers would be greatly appreciated! Thanks! Thomas
