doShift vs mplayer
by Nathaniel Filardo 10 Apr '11

10 Apr '11

Hi all, I wasn't able to find a solution to this, though it's possible I missed some previous discussion. If my manageHook contains "title =? "MPlayer" --> doShift wkM" then, as expected, MPlayer's windows get sent to wkM. However, unless wkM is currently on screen, mplayer does not begin playing. If I bring wkM on screen, it starts, and when I bring something else onscreen instead, mplayer continues to play. FWIW, This is a pretty stock Debian testing machine. Suggestions? Thanks in advance. --nwf;

detecting multi-head and other newbie questions
by Mike Linksvayer 09 Apr '11

Hi, Thanks for xmonad; it's my first attempt to use a tiling WM, and is mostly easy, enjoyable, and very fast. I have a few questions that I haven't been able to answer with a bit of searching and trying. I'm using Ubuntu 10.10 and the package xmonad 0.9.1-2build2. ... http://www.haskell.org/haskellwiki/Xmonad/Frequently_asked_questions#Multi_… ghc -e Graphics.X11.Xinerama.compiledWithXinerama Output is True. ghc -e "Graphics.X11.openDisplay [] >>= Graphics.X11.Xinerama.getScreenInfo" Output is [Rectangle {rect_x = 0, rect_y = 0, rect_width = 1280, rect_height = 800}] However, /usr/bin/gnome-display-properties also sees a 1680x1050 external monitor (but can't activate it when running from xmonad; works fine in GNOME). The xmonad FAQ says (given above) "there may be a problem with your X server configuration." I'm not that keen to mess with X configuration, which I haven't had to do in many years, and I'd like it to continue just working if I ever go back to GNOME. I've never modified anything in /etc/X11 on this machine ... I guess I don't know how monitor autodetection/configuration works, nor what accomplishes that (X? GNOME?), thus am completely clueless as to what approach to take to getting it to work under xmonad. Any hint would be much appreciated. ... Is it possible to make xmobar auto-hide? ... Many examples such as http://www.haskell.org/haskellwiki/Xmonad/Config_archive/John_Goerzen%27s_C… suggest starting related programs in .xsession or .xinitrc but http://www.haskell.org/haskellwiki/Xmonad/Using_xmonad_in_Ubuntu#Configurat… suggets putting them in xmonad.hs which seems cleaner to me. I've done this, though sometimes after reloading xmonad with mod-q, applets no longer appear in trayer, though they're still running. Is there a "right way" that I'm missing? FWIW, here is my xmonad.hs import XMonad import XMonad.Hooks.DynamicLog import XMonad.Hooks.ManageDocks import XMonad.Util.Run(spawnPipe) import XMonad.Util.Run(unsafeSpawn) import XMonad.Util.EZConfig(additionalKeys) import System.IO myManageHook = composeAll [ className =? "Gimp" --> doFloat , className =? "Vncviewer" --> doFloat ] main = do xmproc <- spawnPipe "/usr/bin/xmobar /home/cclearn/.xmobarrc" unsafeSpawn "if [ -x /usr/bin/trayer ] ; then trayer --edge top --align right --SetDockType true --SetPartialStrut true --expand true --width 10 --transparent true --tint 0x191970 --height 12 & fi" unsafeSpawn "if [ -x /usr/bin/nm-applet ] ; then nm-applet --sm-disable & fi" unsafeSpawn "if [ -x /usr/bin/gnome-power-manager ] ; then gnome-power-manager & fi" unsafeSpawn "if [ -x /usr/bin/xscreensaver ] ; then xscreensaver & fi" xmonad $ defaultConfig { manageHook = manageDocks <+> myManageHook -- make sure to include myManageHook definition from above <+> manageHook defaultConfig , layoutHook = avoidStruts $ layoutHook defaultConfig , logHook = dynamicLogWithPP $ xmobarPP { ppOutput = hPutStrLn xmproc , ppTitle = xmobarColor "green" "" . shorten 50 } , modMask = mod4Mask -- Rebind Mod to the Windows key } `additionalKeys` [ ((mod4Mask .|. shiftMask, xK_z), spawn "xscreensaver-command -lock") , ((controlMask, xK_Print), spawn "sleep 0.2; scrot -s") , ((0, xK_Print), spawn "scrot") ] Thanks, Mike

Full example of IndependentScreens
by Ola Karlsson 08 Apr '11

08 Apr '11

Hi Xmonad list.. Am a new user of Xmonad coming from awesome due to having to use Gnome at work and Xmonads Gnome integration is real nice.. Have one problem though , Multiple Screens , can't wrap my head around how xmonad handles that default and want to go for the way I'm used to have it work with separate workspaces for each screen.. Found the IndependentScreens thing in the documentation but can't figure out how to get it in the configuration so needs some help.. Could someone give me a working example of a Gnome enables xmonad config that uses IndependentScreens? Regards /Ola Karlsson

Issue 442 in xmonad: --recompile should support arguments to GHC
by codesite-noreply＠google.com 07 Apr '11

07 Apr '11

Status: New Owner: ---- New issue 442 by k04j...@gmail.com: --recompile should support arguments to GHC http://code.google.com/p/xmonad/issues/detail?id=442 What steps will reproduce the problem? 1. In your xmonad.hs, add an import to a missing module 2. Try to recompile 3. Watch xmonad present you a message suggesting you pass the -v argument to see what folders it's searching. Try passing -v to xmonad --recompile and get the same error. What is the expected output? What do you see instead? What I'd like to see is for --recompile to forward any arguments after it to the compiler, or for there to be a separate --args argument if that's preferable. What version of the product are you using? On what operating system? 0.9, ubuntu linux

Xmonad-contrib AppLauncher
by Mats Rauhala 05 Apr '11

05 Apr '11

The XMonad AppLauncher doesn't work properly with filenames with spaces. It seems to be because it uses the 'spawn' function from core. I replaced the spawn with safeSpawn from XMonad.Utils.Run for my instance, but I'm not sure how it would affect the "grand plan". I also can't make a patch since the tests fail on -fglasgow-exts.
