Getting xmonad working with GNOME 3.8?
by William Ting 23 Feb '14

23 Feb '14

Hi, I've been using xmonad in GNOME 3.2 / 3.4 / 3.6 in fallback mode just fine, but the latest upgrade to GNOME 3.8 on Arch has rendered xmonad unusable. Does anybody know how to get xmonad working on GNOME again? Thanks, William

better combineTwoP and Property

I modified combineTwoP and Property. http://hpaste.org/45435/combinetwoqb New name is combineTwoQB Now windows use full screen space always! (It was bug in combineTwoP, when all windows are in one pane only) Now you can use IsDialog property to detect dialog windows. Version with simplified config: http://hpaste.org/45439/combinetwoqb data Property = Title String | ClassName String | Resource String | Role String -- ^ WM_WINDOW_ROLE property | Machine String -- ^ WM_CLIENT_MACHINE property | And Property Property | Or Property Property | Not Property | IsDialog -- ^^^^^ _NET_WM_WINDOW_TYPE _NET_WM_WINDOW_TYPE_DIALOG | AtomProperty String String | Const Bool deriving (Read, Show) infixr 9 `And` infixr 8 `Or` -- | Does given window have this property? hasProperty :: Property -> Window -> X Bool hasProperty (Title s) w = withDisplay $ \d -> fmap (Just s ==) $ io $ fetchName d w hasProperty (Resource s) w = withDisplay $ \d -> fmap ((==) s . resName ) $ io $ getClassHint d w hasProperty (ClassName s) w = withDisplay $ \d -> fmap ((==) s . resClass) $ io $ getClassHint d w hasProperty (Role s) w = withDisplay $ \d -> fmap ((==) (Just s)) $ getStringProperty d w "WM_WINDOW_ROLE" hasProperty (Machine s) w = withDisplay $ \d -> fmap ((==) (Just s)) $ getStringProperty d w "WM_CLIENT_MACHINE" hasProperty (IsDialog) w = hasProperty (AtomProperty "_NET_WM_WINDOW_TYPE" "_NET_WM_WINDOW_TYPE_DIALOG") w hasProperty (AtomProperty sKey sValue) w = withDisplay $ \d -> checkAtomProperty d w sKey sValue hasProperty (And p1 p2) w = do { r1 <- hasProperty p1 w; r2 <- hasProperty p2 w; return $ r1 && r2 } hasProperty (Or p1 p2) w = do { r1 <- hasProperty p1 w; r2 <- hasProperty p2 w; return $ r1 || r2 } hasProperty (Not p1) w = do { r1 <- hasProperty p1 w; return $ not r1 } hasProperty (Const b) _ = return b -- | Does the focused window have this property? focusedHasProperty :: Property -> X Bool focusedHasProperty p = do ws <- gets windowset let ms = W.stack $ W.workspace $ W.current ws case ms of Just s -> hasProperty p $ W.focus s Nothing -> return False -- | Find all existing windows with specified property allWithProperty :: Property -> X [Window] allWithProperty prop = withDisplay $ \dpy -> do rootw <- asks theRoot (_,_,wins) <- io $ queryTree dpy rootw hasProperty prop `filterM` wins -- | Convert property to 'Query' 'Bool' (see "XMonad.ManageHook") propertyToQuery :: Property -> Query Bool propertyToQuery (Title s) = title =? s propertyToQuery (Resource s) = resource =? s propertyToQuery (ClassName s) = className =? s propertyToQuery (Role s) = stringProperty "WM_WINDOW_ROLE" =? s propertyToQuery (Machine s) = stringProperty "WM_CLIENT_MACHINE" =? s propertyToQuery (IsDialog) = propertyToQuery (AtomProperty "_NET_WM_WINDOW_TYPE" "_NET_WM_WINDOW_TYPE_DIALOG") propertyToQuery (AtomProperty k v) = (ask >>= (\w -> liftX $ withDisplay $ \d -> checkAtomProperty d w k v)) =?

Issue 533 in xmonad: clearUrgency should be exported from XMonad.Hooks.UrgencyHook

Status: New Owner: ---- New issue 533 by JohnTy...(a)gmail.com: clearUrgency should be exported from XMonad.Hooks.UrgencyHook http://code.google.com/p/xmonad/issues/detail?id=533 I was trying to make it such that windows which are banished off screen on hidden scratch pad workspaces *never* get urgency set. It was not possible to do so without making my own Urgency Hook, which was fine, except that in order to make it I had no choice but to modify the source and add clearUrgency to the export list. Since "clearUrgents" is exported, which just applies "clearUrgency" to all windows, I don't see why the latter shouldn't also be available. data FilterUrgencyHook = FilterUrgencyHook [String] instance UrgencyHook FilterUrgencyHook where urgencyHook (FilterUrgencyHook skips) w = do ws <- gets windowset case W.findTag w ws of Just tag -> when (tag `elem` skips) (clearUrgency w) _ -> return () -- You received this message because this project is configured to send all issue notifications to this address.

Issue 498 in xmonad: Borders are not around the window with the focus
by codesite-noreply＠google.com 26 Jul '13

26 Jul '13

Status: New Owner: ---- New issue 498 by rlblas...(a)gmail.com: Borders are not around the window with the focus http://code.google.com/p/xmonad/issues/detail?id=498 What steps will reproduce the problem? 1. Open a terminal and open a file from it in evince. E.g. type "evince a.pdf &" (assuming a.pdf exists in the current directory). 2. Now evince comes into the focus, it has the borders around its window. 3. Go back to the terminal and type "evince a.pdf". This should refresh evince. 4. Observe that evince is in focus by pressing j/k or other evince shortcuts. 5. Also observe that the terminal's window still has borders around it like it's in focus. Basically the focus and the border decoration is not in sync. One of the applications should have both the focus and the border. $ xmonad --version xmonad 0.10

Issue 436 in xmonad: XMonad.Layout.IM doesn't match UTF8 chars

Status: New Owner: ---- New issue 436 by o.a.stephens: XMonad.Layout.IM doesn't match UTF8 chars http://code.google.com/p/xmonad/issues/detail?id=436 I am encountering the same issue as per http://code.google.com/p/xmonad/issues/detail?id=302 using his same test case. What steps will reproduce the problem? 1. Configure withIM layout to match a window title with UTF8 chars as roster. Ex: withIM (1%7) (Title "foo™") (Tall 1 0.5 0.5) 2. Run a window with the configured name. Ex: xterm -T "foo™" -e read What is the expected output? What do you see instead? The window should be placed as withIM layout roster. In this case, on a separated column to the left. What version of the product are you using? On what operating system? Latest XMonad Darcs on Arch X86_64. Are you using an xmonad.hs? Please attach it and the output of "xmonad --recompile". No output from xmonad --recompile. Please provide any additional information below. Comments from #xmonad having queried my issue: <allbery_b> I'm looking at darcs... WindowProperties uses the ManageHook code (!! --- more evidence that it's mis-typed) and ManageHook.hs in the core uses getStringProperty everywhere <allbery_b> (in particular it's using it for _NET_WM_* which is completely wrong as they are all defined as Unicode stored as 32 bit lists) <allbery_b> suggest you reopen that bug report, or file a new one about _NET_WM_* being misinterpreted I am attempting to match Skype's window title, which also contains the ™ character.

I > might give it a shot if you don't have time, though. thanks for spotting the issue! It’s been a while since I hacked on xmonad, and I don’t see an immediate fix. Some way to approach it would be to extend the xmonad core so that the result of getStrut is stored along with the window. Another way would be to extend the datatype of the AvoidStruts to remember some data. But what? The gap? The strut of each window? Only on the current workspace or everywhere? I suggest you take this discussion on the xmonad mailing list, which I have CCed, and maybe you can come up with a fix!

Issue 432 in xmonad: Module for linking workspaces in a multihead setup

Status: New Owner: ---- New issue 432 by que...(a)gmail.com: Module for linking workspaces in a multihead setup http://code.google.com/p/xmonad/issues/detail?id=432 Hey, I just wanted to share some of the functions I have written for linking workspaces. The idea is that the module maintains a list of workspaces that are linked together. Whenever one switches to one of these workspaces, the other monitors are switched to the linked ones. Maybe it's of interest to someone else. It would be nice if it could be added to contrib. Best regards, Jan Attachments: linkWorkspaces.patch 60.6 KB

fadeInactiveLogHook on dual monitor with nvidia
by Robert Sawko 01 May '13

01 May '13

Dear All, I have two Xmonad configurations that are extremely productive for me and do most if not all of the things I want. One setup is on my latop and another on my desktop at work. The configurations are very similar with the exception that the desktop has an nvidia drivers installed and is running a dual screen. Basically fadeInactiveLogHook is not working. I would like the inactive windows to fade slightly as this helps me focus on the right terminal. Here are the relevant entries from xmonad.hs myLogHook :: Handle -> X () ... main = do ... , logHook = myLogHook dzenLeftBar >> fadeInactiveLogHook 0.8 ... Is there anything I should do more? This setup works on my laptop so is there any known issues with nvidia or dual screen setup? How do I debug this? Please advise, Robert -- Kitchen science (Non-Newtonian series). http://www.youtube.com/watch?v=OCTgFLEYlw4
