Hi Tobias, Thank you for your help. I tried adding the line         , startupHook          = ewmhDesktopsStartup                                                                                                                            but it made no difference. What I have realized, though, is that wmctrl correctly reports on which workspace each window is when I am running my laptop in "standalone" mode (ie, without external screens). When I plug in an  external screen, suddenly wmctrl -l reports all windows as being in the currently active workspace: 0x02000005  2 ubuntu root@ubuntu: ~ 0x02c000a3  2 ubuntu Mozilla Firefox 0x0200015c  2 ubuntu l@ubuntu: ~ if I workspace 2 currently has focus and if, eg, workspace 0 has focus then 0x02000005  0 ubuntu root@ubuntu: ~ 0x02c000a3  0 ubuntu Yahoo! Mail - Mozilla Firefox 0x0200015c  0 ubuntu l@ubuntu: ~ Any idea on how I might fix this? Does it have to do with xinerama? thanks! ~l ----- Original Message ----- From: Tobias Hommel To: Lara Michaels Cc: "xmonad@haskell.org" Sent: Wednesday, June 27, 2012 12:32 PM Subject: Re: [xmonad] "wmctrl -l" lists all my windows as being on the same workspace (0) Hey Lara, for me wmctrl works, but I have an additional line in my config:         , startupHook          = ewmhDesktopsStartup                                                                                                                            From the documentation:

Initializes EwmhDesktops and advertises EWMH support to the X server Maybe this solves your problem.

Hello,

When I run wmctrl -l, it lists all my windows as being on the same workspace (workspace 0):

0x03600005  0 ubuntu l@ubuntu: ~ 0x02a000a3  0 ubuntu Mozilla Firefox 0x03a000a3  0 ubuntu Inbox - Local Folders - Mozilla Thunderbird

However, when I run wmctrl -d it "knows" xmonad is using 7 workspaces named "1" through "7":

0  * DG: N/A  VP: N/A  WA: N/A  1 1  - DG: N/A  VP: N/A  WA: N/A  2 2  - DG: N/A  VP: N/A  WA: N/A  3 3  - DG: N/A  VP: N/A  WA: N/A  4 4  - DG: N/A  VP: N/A  WA: N/A  5 5  - DG: N/A  VP: N/A  WA: N/A  6 6  - DG: N/A  VP: N/A  WA: N/A  7

How can I get wmctrl to play nicely with xmonad? From searching the web I thought this would do the trick:

import XMonad.Hooks.EwmhDesktops

main =  do     xmonad $ ewmh gnomeConfig { modMask = mod4Mask                        , manageHook = manageDocks  manageHook defaultConfig                        , workspaces = myWorkspaces                        , normalBorderColor  = "#cccccc"                        , focusedBorderColor = "#cd8b00"                        , borderWidth = 3                        , layoutHook = showWName myLayout                        , logHook =  ewmhDesktopsLogHook <+> dynamicLogXinerama                        , handleEventHook = ewmhDesktopsEventHook                        } `additionalKeysP` myKeys

but wmctrl still says all windows are on workspace 0.

thank you for any help ~l
