+18:17 < Biolunar> when i change my resolution in dwm (to a smaller one) and then back to the native, the top bar is not repainted. that's since 5.7.2, in 5.6 it worked fine
+18:19 < Biolunar> is it just happening to me or a (known) bug?
+18:24 < Biolunar> and in addition, mplayers fullscreen is limited to the small resolution after i changed it back to the native

+

+if there is no client on the other monitor to get the focus, then the
+terminal will be unfocused but it will accept input

+starting emacs from dmenu in archlinux results in missing configure of emacs, but mod1-space or mod1-shift-space fix this problem. this problem is new and did not happen in 1.6 xorg servers

+
+This is a known bug (for some curiosity I received the same report via
+privmail from 2 other people within one week, really strange).
+The quick fix is commenting out the code in lines 817/818 in hg tip
+dwm. I cannot confirm this has no side effects (I think it does) and I
+will address this issue shortly with a real fix.

+
+Patching SDL, bugging them?
+

+
+voltaic reports this:
+
+When I use two monitors, one larger in resolution than the other, the
+bar is drawn using the smaller x-dimension on both screens. I think
+what's happening is that there are two bars drawn, but the short bar
+is always on top of the long bar such that I can't see the information
+under the short bar. If I switch to the small screen, hide the short
+bar, and then switch to the large screen, the long bar is drawn
+correctly.
+
+A similar problem occurs when I have started dwm on a small resolution
+monitor (laptop screen) and then I switch to a large external display.
+When I do this, the bar itself is drawn for the original smaller
+resolution, but the information to be printed on the bar is
+right-aligned for a longer bar. So what I see is a bar that has the
+right hand side of it cut-off. See attached screenshot.
+
+I am using standard options for xrandr such as --output VGA1 --auto, etc.

+dwm - dynamic window manager
+============================
+dwm is an extremely fast, small, and dynamic window manager for X.
+
+
+Requirements
+------------
+In order to build dwm you need the Xlib header files.
+
+
+Installation
+------------
+Edit config.mk to match your local setup (dwm is installed into
+the /usr/local namespace by default).
+
+Afterwards enter the following command to build and install dwm (if
+necessary as root):
+
+ make clean install
+
+If you are going to use the default bluegray color scheme it is highly
+recommended to also install the bluegray files shipped in the dextra package.
+
+
+Running dwm
+-----------
+Add the following line to your .xinitrc to start dwm using startx:
+
+ exec dwm
+
+In order to connect dwm to a specific display, make sure that
+the DISPLAY environment variable is set correctly, e.g.:
+
+ DISPLAY=foo.bar:1 exec dwm
+
+(This will start dwm on display :1 of the host foo.bar.)
+
+In order to display status info in the bar, you can do something
+like this in your .xinitrc:
+
+ while xsetroot -name "`date` `uptime | sed 's/.*,//'`"
+ do
+ sleep 1
+ done &
+ exec dwm
+
+
+Configuration
+-------------
+The configuration of dwm is done by creating a custom config.h
+and (re)compiling the source code.

+.SH NAME
+dwm \- dynamic window manager
+.SH SYNOPSIS
+.B dwm
+.RB [ \-v ]
+.SH DESCRIPTION
+dwm is a dynamic window manager for X. It manages windows in tiled, monocle
+and floating layouts. Either layout can be applied dynamically, optimising the
+environment for the application in use and the task performed.
+.P
+In tiled layouts windows are managed in a master and stacking area. The master
+area contains the window which currently needs most attention, whereas the
+stacking area contains all other windows. In monocle layout all windows are
+maximised to the screen size. In floating layout windows can be resized and
+moved freely. Dialog windows are always managed floating, regardless of the
+layout applied.
+.P
+Windows are grouped by tags. Each window can be tagged with one or multiple
+tags. Selecting certain tags displays all windows with these tags.
+.P
+Each screen contains a small status bar which displays all available tags, the
+layout, the title of the focused window, and the text read from the root window
+name property, if the screen is focused. A floating window is indicated with an
+empty square and a maximised floating window is indicated with a filled square
+before the windows title. The selected tags are indicated with a different
+color. The tags of the focused window are indicated with a filled square in the
+top left corner. The tags which are applied to one or more windows are
+indicated with an empty square in the top left corner.
+.P
+dwm draws a small border around windows to indicate the focus state.
+.SH OPTIONS
+.TP
+.B \-v
+prints version information to standard output, then exits.
+.SH USAGE
+.SS Status bar
+.TP
+.B X root window name
+is read and displayed in the status text area. It can be set with the

+command.
+.TP
+.B Button1
+click on a tag label to display all windows with that tag, click on the layout
+label toggles between tiled and floating layout.

+.TP
+.B Mod1\-Shift\-[1..n]
+Apply nth tag to focused window.
+.TP
+.B Mod1\-Shift\-0
+Apply all tags to focused window.
+.TP
+.B Mod1\-Control\-Shift\-[1..n]
+Add/remove nth tag to/from focused window.
+.TP

+View all windows with nth tag.
+.TP
+.B Mod1\-0
+View all windows with any tag.
+.TP
+.B Mod1\-Control\-[1..n]
+Add/remove all windows with nth tag to/from the view.
+.TP
+.B Mod1\-Shift\-q
+Quit dwm.
+.SS Mouse commands
+.TP
+.B Mod1\-Button1
+Move focused window while dragging. Tiled windows will be toggled to the floating state.
+.TP
+.B Mod1\-Button2
+Toggles focused window between floating and tiled state.
+.TP
+.B Mod1\-Button3
+Resize focused window while dragging. Tiled windows will be toggled to the floating state.
+.SH CUSTOMIZATION
+dwm is customized by creating a custom config.h and (re)compiling the source
+code. This keeps it fast, secure and simple.
+.SH SEE ALSO
+.BR dmenu (1)
+.SH BUGS
+Java applications which use the XToolkit/XAWT backend may draw grey windows
+only. The XToolkit/XAWT backend breaks ICCCM-compliance in recent JDK 1.5 and early
+JDK 1.6 versions, because it assumes a reparenting window manager. Possible workarounds
+are using JDK 1.4 (which doesn't contain the XToolkit/XAWT backend) or setting the
+environment variable
+.BR AWT_TOOLKIT=MToolkit
+(to use the older Motif backend instead) or running
+.B xprop -root -f _NET_WM_NAME 32a -set _NET_WM_NAME LG3D
+or
+.B wmname LG3D
+(to pretend that a non-reparenting window manager is running that the
+XToolkit/XAWT backend can recognize) or when using OpenJDK setting the environment variable
+.BR _JAVA_AWT_WM_NONREPARENTING=1 .
+.P
+GTK 2.10.9+ versions contain a broken
+.BR Save\-As
+file dialog implementation,
+which requests to reconfigure its window size in an endless loop. However, its
+window is still respondable during this state, so you can simply ignore the flicker
+until a new GTK version appears, which will fix this bug, approximately
+GTK 2.10.12+ versions.

+ *
+ * dynamic window manager is designed like any other X client as well. It is
+ * driven through handling X events. In contrast to other X clients, a window
+ * manager selects for SubstructureRedirectMask on the root window, to receive
+ * events about window (dis-)appearance. Only one X connection at a time is
+ * allowed to select for this event mask.
+ *
+ * The event handlers of dwm are organized in an array which is accessed
+ * whenever a new event has been fetched. This allows event dispatching
+ * in O(1) time.
+ *
+ * Each child of the root window is called a client, except windows which have
+ * set the override_redirect flag. Clients are organized in a linked client
+ * list on each monitor, the focus history is remembered through a stack list
+ * on each monitor. Each client contains a bit array to indicate the tags of a
+ * client.
+ *
+ * Keys and tagging rules are organized as arrays and defined in config.h.
+ *
+ * To understand everything else, start reading main().
