master window with fixed pixels layout.
by Alejandro Garcia 25 Jan '20

25 Jan '20

Hello first of all thank you for xmonad. the seconds I have saved every day by not having o drag and drop windows has given me more time to focus on what matters. get the job done and go home to play with my kids. I would like to know: Is there a window layout with the property that the width and height of the master window can be specified in pixels? my use case Is that I would like to record video casts. But it would be helpful for me if the window size of the master window stays fixed independently of the other windows open in the screen. I have checke FixedColumns. but on it the Width of the column is specified in a rare metric (characters?) plus the height is not fixed. Any recommendation ? Thanks in advance. -- Alejandro García F.

Refresh display, adapting to monitor resolution
by Jean-Baptiste Mestelan 11 Jan '20

Hello, Is there a way to have XMonad adapt the display to the resolution of the plugged monitor(s)? My problem is: at home, I have the laptop attached to one monitor. I suspend the session (systemctl hibernate), and resume it at work where I use a higher-resolution monitor. The display remains as it was set when starting the X session. The only way I have found to have the new monitor settings detected is to restart the X session (slim restart), which obviously kills user programs. So the question is: is there a command I can run to have the display adapt to the capabilities of the current monitor? Thanks for attention.

Is there a better way to write new layout? (Also modified Tall layout inside)
by Dusan Popovic 06 Jan '20

Hi, With being near impossible to get any non 16:9 monitor, and using big monitor (27" or bigger), any single terminal/editor takes entire screen when using Tall layout. This makes all the text aligned at the left edge of the monitor, which forces me to either sit facing the left half of the monitor or stretch my neck 90+% of time. I decided to modify Tall layout, so that with single window open it doesn't take all the space, while with more than one window open it behaves exactly as Tall already does. I am really beginner in haskell but I can do basic stuff, so I chopped built in Tall layout, modified it a bit, added to xmonad.hs. While it works well I am convinced there must be more elegant way to do the same, so I am curious how to do it better. Steps I took to make it work: 1. Chop LANGUAGE directive from xmonad-git/src/XMonad/Layout.hs and add to my xmonad.hs at the top. I would love to avoid having FlexibleInstances in my xmonad.hs. {-# LANGUAGE FlexibleInstances, MultiParamTypeClasses, PatternGuards, TypeSynonymInstances, DeriveDataTypeable #-} 2. Chop and modify Tall layout, add it to xmonad.sh, most important part being 'tile54 f (Rectangle sx sy sw sh) nmaster 1' function that matches when there is only one window. import Control.Arrow ((***), second) import Control.Monad import Graphics.X11 (Rectangle(..)) data Tall54 a = Tall54 { tallNMaster :: !Int -- ^ The default number of windows in the master pane (default: 1) , tallRatioIncrement :: !Rational -- ^ Percent of screen to increment by when resizing panes (default: 3/100) , tallRatio :: !Rational -- ^ Default proportion of screen occupied by master pane (default: 1/2) } deriving (Show, Read) instance LayoutClass Tall54 a where pureLayout (Tall54 nmaster _ frac) r s = zip ws rs where ws = W.integrate s rs = tile54 frac r nmaster (length ws) pureMessage (Tall54 nmaster delta frac) m = msum [fmap resize (fromMessage m) ,fmap incmastern (fromMessage m)] where resize Shrink = Tall54 nmaster delta (max 0 $ frac-delta) resize Expand = Tall54 nmaster delta (min 1 $ frac+delta) incmastern (IncMasterN d) = Tall54 (max 0 (nmaster+d)) delta frac description _ = "Tall54" tile54 :: Rational -- ^ @frac@, what proportion of the screen to devote to the master area -> Rectangle -- ^ @r@, the rectangle representing the screen -> Int -- ^ @nmaster@, the number of windows in the master pane -> Int -- ^ @n@, the total number of windows to tile -> [Rectangle] tile54 f (Rectangle sx sy sw sh) nmaster 1 = [Rectangle sx1 sy sw1 sh] where sx1 = sx + sm1 sm1 = fromIntegral (sw - sw1) `div` 2 sw1 = 5 * fromIntegral (sh `div` 4) tile54 f r nmaster n = if n <= nmaster || nmaster == 0 then splitVertically n r else splitVertically nmaster r1 ++ splitVertically (n-nmaster) r2 -- two columns where (r1,r2) = splitHorizontallyBy f r 3. Add new layout in the list, keeping standard Tall as second one. In rare cases when I want single window taking entire screen I can switch to Tall. As a result, when I open single terminal or editor window it is centered, simulating old 5:4 monitors. More than one window and it is standard Tall layout. I have attached my xmonad.hs if somebody wants to try. So finally questions: 1. Anybody needs this apart from me? How do you cope with 'teaminal/editor being too far to the left'? 2. Is there a better way to write this layout (in xmonad.hs) without butchering parts of code from Layout.hs? Since I am learning haskell I believe any pointers would be very useful. Cheers, Dusan
