Description Sam Morris 2008-06-05 09:39:28 UTC 
Metacity sometimes goes into a strange mode where it will take two presses of alt+tab to change focus to another window. Pressing it once activates alt+tab mode, but does not shift the focus away from the current window.
Comment 1 Thomas Thurman 2008-06-05 13:14:53 UTC 
Is there a reliable way to reproduce this?
Comment 2 Sam Morris 2008-06-05 13:21:38 UTC 
Unfortunately not. It just kind of happens, occasionally, until I kill metacity.
Comment 3 Sam Morris 2008-06-17 17:48:45 UTC 
This has just struck me again--can I get any kind of info out of metacity as to WTF is going on?
Comment 4 Sam Morris 2008-06-17 18:06:30 UTC 
I can reproduce the bug!

 1. Put some images in a directory
 2. Run xterm
 3. In the xterm, run xwininfo
 4. When the mouse pointer turns into a cross, click the xterm window
 5. Make a note of the window id (looks like '0x2c00024').
 6. Run this command: while true; do xscreensaver-getimage $window_id ; sleep 1; done
 7. Switch to another workspace with a few windows on it
 8. Wait for the xterm window to go into urgent state (that is, it appears in the window list as bold and flashing blue)
 9. Now press alt+tab once. Instead of switching windows, you switch to the currently-focused window. Pressing it twice switches to another window.

Phew!

BTW I'm using metacity 2.22.0 from Debian. We don't patch the code other than to link with -Wl,as-needed.
Comment 5 Sam Morris 2008-06-17 18:10:34 UTC 
Oh, you have to make sure you have the following in ~/.xscreensaver first:

imageDirectory:	/path/to/pictures/directory
chooseRandomImages: True
