More trouble with KDE apps
by John Goerzen 15 Jun '09

15 Jun '09

Hi folks, I wrote a couple of weeks ago that kpowermon opened a full window with its icon, rather than going in the tray. That was annoying, but today I discover Amarok is doing the same thing. That's MORE annoying, because I really want to use it. So it opens a full window with junk in it, except the center, which has its small tray-sized icon. This in additional to its regular window, of course. Any ideas what to do about this? This is KDE 4. The majority of apps work just fine, both KDE and Gnome, but a few are misbehaving strangely like this. Again, I did not have the problem before switching to xmonad. I am using the KDE configs in xmonad. -- John

xmobar high cpu usage
by Chengqi(Lars) Song 14 Jun '09

14 Jun '09

hi, does anyone else have this problem? xmobar occasionally takes up high cpu usage. In 'top', it appears X is using to much cpu, but using oprofile, I found it's xmobar who is using the CPU. Restart xmobar solves this problem. Thanks lars

Multi Head Setups with Newer Xorg?
by Matt Brown 14 Jun '09

14 Jun '09

Hi All, Since upgrading my ubuntu install (and breaking my multi head xmonad setup), I've been reading a lot about how xinerama is broken for newer xorgs, and is deprecated in favor of xrandr (which doesn't handle multi-head on more than one card). Looks like my only option is to revert back to ubuntu 8.04, or dump some screens. How are you dealing with this? Has anyone found a workaround? -matt

xmonad Gnome Bar config
by Alexey Feigin 11 Jun '09

11 Jun '09

Hi, I have a config similar to John Yates' Gnome bar config, but the dzen2 bar appears behind the Gnome bar. Is there simple way to solve this? Perhaps there's a command to raise window to the front that I can use at startup? Cheers, Alexey

Get mouse to follow cursor
by Magnus Ågren 10 Jun '09

10 Jun '09

Hi When I move to a new window I would like the mouse pointer to be at the same position as the text cursor. Does anyone have a solution to this? I would like this since I use http://linuxaleph.blogspot.com/2008/11/mapping-middle-click-to-keyboard-key… to be able to paste text using the keyboard, and for this to work for example in a browser input field the mouse must follow the text cursor. Currently I use import XMonad.Actions.UpdatePointer and logHook = updatePointer (Relative 0.5 0.5) to get the pointer to at least follow the focused window. Thanks in advance. Magnus

Issue 300 in xmonad: XMonad.Prompt.Shell doesn't escape ampersands in tab completed file names.

Comment #2 on issue 300 by gwern0: XMonad.Prompt.Shell doesn't escape ampersands in tab completed file names. http://code.google.com/p/xmonad/issues/detail?id=300 This is actually already fixed in darcs, I think. Thu Mar 12 05:13:14 EDT 2009 Valery V. Vorotyntsev <valery.vv(a)gmail.com> * Prompt.Shell: escape ampersand Ampersand (&) is a special character and should be escaped. { hunk ./XMonad/Prompt/Shell.hs 121 -escape (' ':xs) = "\\ " ++ escape xs hunk ./XMonad/Prompt/Shell.hs 126 -isSpecialChar = flip elem "\\@\"'#?$*()[]{};" +isSpecialChar = flip elem " &\\@\"'#?$*()[]{};" } -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.

Status: New Owner: ---- New issue 300 by ha...(a)haeg.in: XMonad.Prompt.Shell doesn't escape ampersands in tab completed file names. http://code.google.com/p/xmonad/issues/detail?id=300 What steps will reproduce the problem? 1. Open the XMonad.Prompt.Shell (using DefaultXPConfig but this may not be necessary). 2. Use tab completion to enter a file name containing an ampersand. 3. Observe that the ampersand is not backslash escaped and thus the filename is not processed correctly. What is the expected output? What do you see instead? The ampersand should be backslash escaped in the prompt but it is not. What version of the product are you using? On what operating system? xmonad 0.8 on 2.6.28-11-generic #42-Ubuntu (64bit) with xmonad-contrib-0.8 Are you using an xmonad.hs? Please attach it and the output of "xmonad --recompile". Yes, see attached for xmonad.hs. xmonad --recompile produces no output so I didn't attach it. Please provide any additional information below. I have also attached a patch that I think fixes this problem.

Why isn't mappend for Query flipped?
by Brent Yorgey 10 Jun '09

10 Jun '09

In XMonad.Core, we have type ManageHook = Query (Endo WindowSet) newtype Query a = Query (ReaderT Window X a) deriving (Functor, Monad, MonadReader Window, MonadIO) instance Monoid a => Monoid (Query a) where mempty = return mempty mappend = liftM2 mappend So 'mappend' for Query is just the 'mappend' for Endo, lifted over the ReaderT. But of course, 'mappend' for Endo is just function composition. The upshot is that m1 <+> m2 does m2, and THEN m1. Mostly no one notices since ManageHooks tend to consist of a bunch of actions with disjoint premises, so it doesn't matter in which order they are run. But this order is quite counterintuitive when trying to sequence multiple actions in a ManageHook (as someone was just trying to do in #xmonad today, which is how I ran across this issue). I propose to change the Monoid instance for Query so that mappend = liftM2 (flip mappend) Of course, this has the undesirable side effect of breaking any configs where the order actually matters. But it would certainly make more sense moving forward, IMO. Thoughts? -Brent
