xmonad screenshot hotkeys

Install scrot.  Add the following to the key bindings portion of your /home/USER/.xmonad/xmonad.hs file.

   --take a screenshot of entire display
   , ((modm , xK_Print ), spawn "scrot screen_%Y-%m-%d-%H-%M-%S.png -d 1")

   --take a screenshot of focused window
   , ((modm .|. controlMask, xK_Print ), spawn "scrot window_%Y-%m-%d-%H-%M-%S.png -d 1-u")

then refresh xmonad with mod+q.  XK_Print is the Print Screen keysym name.  Now mod+PrtScr will take a screen shot of the entire display, and ctrl+mod+PrtScr will take a screen shot of the focused window.  The captured image is placed in the /home/USER/ directory.  The file name is prefixed either window or screen, and date+time stamped.  You can use the -e option of scrot to move the resulting file to a different directory.  For example:  scrot window_%Y-%m-%d-%H-%M-%S.png -d 1 -u -e 'mv $f /home/USER/image/'.  the $f is the scrot variable for the captured image path.
   Here is my current xmonad.hs file, which is this xmonad.hs example with some minor modifications.

--
-- Normally, you'd only override those defaults you care about.
--
-- NOTE: Those updating from earlier xmonad versions, who use
-- EwmhDesktops, safeSpawn, WindowGo, or the simple-status-bar
-- setup functions (dzen, xmobar) probably need to change
-- xmonad.hs, please see the notes below, or the following
-- link for more details:

-- modMask lets you specify which modkey you want to use. The default
-- is mod1Mask ("left alt").  You may also consider using mod3Mask
-- ("right alt"), which does not conflict with emacs keybindings. The
-- "windows key" is usually mod4Mask.
--
myModMask       = mod4Mask
 
-- NOTE: from 0.9.1 on numlock mask is set automatically. The numlockMask
-- setting should be removed from configs.
--
-- You can safely remove this even on earlier xmonad versions unless you
-- need to set it to something other than the default mod2Mask, (e.g. OSX).
--
-- The mask for the numlock key. Numlock status is "masked" from the
-- current modifier status, so the keybindings will work with numlock on or
-- off. You may need to change this on some systems.
--
-- You can find the numlock modifier by running "xmodmap" and looking for a
-- modifier with Num_Lock bound to it:
--
-- > $ xmodmap | grep Num
-- > mod2        Num_Lock (0x4d)
--
-- Set numlockMask = 0 if you don't have a numlock key, or want to treat
-- numlock status separately.

PTP camera with Xmonad

My camera supports the Picture Transfer Protocol (PTP) rather than the USB Mass Storage device Class (UMSC) protocol.  My bare bones debian install could not mount it.  This was easily resolved by installing gphotofs and fuse.

ROOTPROMPT$> apt-get install gphotofs 

Which will also install the fuse dependencies.  Then add the appropriate users to the fuse group.

ROOTPROMPT$> adduser USERNAME fuse

Reboot.  Plug the camera into the computer.  I haven't yet bothered to mount the camera to the /media directory.  I simply made a /home/USER/camera directory and mount to there when I need to move pictures.

$> mkdir /home/USER/camera
$> gphotofs /home/USER/camera

The camera is then mounted to the /home/USER/camera directory as a normal filesystem, and you can traverse it with common commands such as ls, cd, etc..
   The following command unmounts the camera.  This will not work if you have any terminals open to the camera directory.

$> fusermount -u camera
