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?

Shift Spotify to the right workspace

Hi, I have a workspace called "music" and I'm trying to shift the Spotify linux client there. I put this as part of my manage hook, but it doesn't seem to work. Spotify starts up in whatever workspace I happen to be (this works fine for many other apps). , className =? "Spotify" --> doShift "music" , className =? "spotify" --> doShift "music" , title =?

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

xmonad on ubuntu desktop environment
by Steve Quezadas 20 Oct '18

20 Oct '18

Hello, I got a new computer and install ubuntu to 18.04 (Bionic Beaver). When i login through xmonad, my ubuntu desktop environment disappears, it's all black. No wallpaper, no tray, no nothing. My xmonad.hs file is as follows: > import XMonad > import XMonad.Config.Desktop > > baseConfig = desktopConfig > > main = xmonad baseConfig > { modMask = mod4Mask } This config file worked with my previous version of ubuntu and now just loads a black screen. I can get into my terminal window by doing a mod-shift-enter and that's how I get around, but I would like to get back into the ubuntu tray (mod-p, for instance). I tried an alternative configuration on one of the wiki's to no avail. > import XMonad import > XMonad.Config.Gnome > > main = xmonad gnomeConfig Tried googling, checking the wiki's and going through the documentation to no avail. I am thinking maybe there's some error on the logs or something that I can check. or is there something that I'm doing that is obviously wrong? - Steve

How to use PhysicalScreens?
by Robert Sawko 29 Aug '18

29 Aug '18

Hi, I just got myself a second screen which I daisy-chained with the first one, but I am having issues with getting screens to be identified properly. I use xrandr to configure display. The screens are identified as: $ xrandr DP-1-1-8 connected 2560x1440+0+0 (normal left inverted right x axis y axis) 597mm x 336mm 2560x1440 59.95*+ ... DP-1-1-1-8 connected 2560x1440+2560+0 (normal left inverted right x axis y axis) 597mm x 336mm 2560x1440 59.95*+ ... DP-1-1-1-1 disconnected (normal left inverted right x axis y axis) And I set the screen with: xrandr \ --output DP-1-1-1-8 --mode 2560x1440 --right-of DP-1-1-8 \ --output DP-1-1-8 --mode 2560x1440 \ --output eDP-1-1 --off I am reading in here that using Actions.Physical screens involves importing and changing the mapping(?). https://hackage.haskell.org/package/xmonad-contrib-0.14/docs/XMonad-Actions… If I include only the import then nothing changes. The mappings don't compile for me. I am attaching the error below. Not sure, if I am doing something wrong or if the docs are incomplete. What is "W" meant to be?

xmonad --replace works,...
by e.a.gebhart＠gmail.com 22 May '18

22 May '18

I figured it out, and of course it was not Xmonad. which I was pretty sure of. I'm not sure how it was working at all. I had the wrong path in the wrong file. It was one of the many things that I had done while fixing numerous other problems in getting Xmonad to compile and work again. There were just to many things going wrong and I broke the xsession while I was fixing everything else. Sorry to bother the list. Eric
