Transparent borders are back
by Adam Sjøgren 19 Sep '25

19 Sep '25

Many, many moons ago I tried to get the transparent borders I got around Sakura¹ windows to go away. I think the quest - with a lot of help - eventually succeeded back then (https://github.com/xmonad/xmonad/pull/59) Now they are back: Around Firefox 140.3.0esr's windows on Debian 13 (trixie) with xmonad 0.17.2: · https://koldfront.dk/misc/xmonad/firefox-xmonad.png I don't know where to start - has anyone seen/solved this? Best regards, Adam ¹: https://launchpad.net/sakura -- "No more than that, but very powerful all the same; Adam Sjøgren simple things are good." asjo(a)koldfront.dk

New layout for ultrawide monitors
by Miles Sabin 14 Jul '25

14 Jul '25

Hi folks, I've published a new layout for ultrawide monitors. I put this together after trying several of the existing layouts that target ultrawides, but finding that none of them really worked quite the way I wanted. The repo is here, https://github.com/milessabin/ThreeColumnStable There's a small animated demo which is hopefully worth a few thousand words. Any and all feedback would be very much appreciated, including on Haskell style (I'm a functional programmer but not a Haskeller). Cheers, Miles -- Miles Sabin https://bsky.app/profile/milessabin.com https://types.pl/@milessabin https://milessabin.com/blog

Layout demo screen recorder recommendations sought
by Achim D. Brucker 13 Jul '25

13 Jul '25

Hi, To add to the discussion on a layout for screen recording and screen sharing on ultra wide displays: I am using since a few years a layout inspired by ThreColMid (which is my work-horse for daily work), where the resolution of the main window is fixed to a 'standard" resolution. This allows to share the main window without the receiving end being "overwhelmed" or to record the window in the desired video resolution. In addition, I use a nested X server (e.g., Xephyr) to share a "clean" desktop. If anybody is interested to have a look, I put my implementation online: https://git.logicalhacking.com/adbrucker/xmonad-recording-layout Best, Achim

Layout demo screen recorder recommendations sought
by Miles Sabin 12 Jul '25

12 Jul '25

Hi folks, I've been working on a new layout, specifically for ultrawide displays. I'd like to record a demo of the layout in use. Does anyone have any recommendations for software for that, formats to publish in etc. etc. One caveat is that being for ultrawide monitors, the unscaled frame size would be pretty large (5120x1440 for mine) which might present some special issues ... advice would be most welcome.

Re: [xmonad] Just a quesion about an old glibc issue
by Brandon Allbery 18 Feb '25

18 Feb '25

Haskell doesn't use `glibc` (or any other libc) `malloc`,it uses its own heap which is managed separately. Even Haskell's `malloc` (used with FFI) uses Haskell's heap; it allocates a "pinned" block that can't be moved but can still be garbage collected. Any fragmentation issues would need to be fixed in the garbage collector.

Spawn, on new workspace, fullscreen
by Miles Sabin 11 Jan '25

11 Jan '25

Hi folks, I'm struggling with this ... I'm trying to arrange for a keyboard shortcut to launch an application on a fresh workspace with a full screen layout. spawnOn doesn't appear to be paying attention to the workspace id argument ... the window always appears on the current workspace. Ideally I'd also like to immediately navigate to the workspace the app has launched on.

Skipping minimized windows
by Eyal Erez 16 Dec '24

16 Dec '24

Hi, I currently use the following commands to hide windows temporarily: , ((modMask .|. shiftMask, xK_y ), withLastMinimized maximizeWindowAndFocus) , ((controlMask .|. shiftMask, xK_y ), withFocused minimizeWindow) Unfortunately, when I switch focus from window to window, focus still moves to the minimized windows. Meaning that I need to switch through several invisible windows to get to the visible ones. -- Move focus to the next window , ((modMask, xK_k ), windows W.focusDown) -- Move focus to the previous window , ((modMask, xK_j ), windows W.focusUp) Is there a way to modify this so that it skips minimized windows? Thank you, -- There are 10 types of people, those who know binary and those who don't.

DynamicProjects: creating a new project that partially matches predefined project
by Ramon Diaz-Uriarte 01 Nov '24

01 Nov '24

Dear All, I use XMonad.Actions.DynamicProjects. I have a bunch of configured, predefined projects, say one with name "emacs". Now, when I use switchProjectPrompt, I do not know how to create a new (not predefined) project called "em": as soon as I type "em" it matches "emacs" and on pressing enter the "emacs" project is created. The only solution I've found is to type "em1" or similar, to prevent matching but I guess there must be a simpler way that I am missing.

Could not load modules after recent update
by Eyal Erez 26 Oct '24

26 Oct '24

Hi, I use xmonad on arch linux. I've recently updated my system, as one often does, and now my xmonad.hs is failing to compile and I am failing to start xmonad. Here is an example of an error: xmonad.hs:3:1: error: Could not load module ‘XMonad.Actions.CycleWS’ It is a member of the package ‘xmonad-contrib-0.18.1-Hn3tyQ1hgcfBs6gP5hIKJ’ which is unusable due to missing dependencies: random-1.2.1.2-4MvNAJNQIvxGHtrKNblxG1 Use -v (or `:set -v` in ghci) to see a list of the files searched for. | 3 | import XMonad.Actions.CycleWS | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The full log is here: https://pastebin.com/KkFQQSwU It seems that xmonad-contrib is missing the "random" library. I've tried reinstalling xmonad, xmonad-contrib, haskell-random, and any other library I can think of. However, it does not seem to improve the situation. Is there anything I can do to debug this further? Here are some of my installed package versions: xmonad 0.18.0-20 xmonad-contrib 0.18.1-5 haskell-random 1.2.1.2-16 Thank you kindly -- There are 10 types of people, those who know binary and those who don't.
