i might have whined about this in the past. situation is, under certain circumstances (which always involves high (io) load), wm goes into a deadlock on my xinerama setup running on ubuntu 10.04 with the symptom of the mouse pointer oscillating between the two xinerama heads, and not much else happening.
now i think i found the culprit, which is way outside wm, and is rather in xcb, specifically this bug: https://bugs.freedesktop.org/show_bug.cgi?id=27368 http://lists.freedesktop.org/archives/xcb/2010-March/005818.html with the patch mentioned (but cleverly not by any means made readily identifiable, good work, mate) in the bug report applied to the ubuntu libxcb, i'm stressing the whole shebang for almost an hour now under considerable (for a desktop) load, and it still hasn't deadlocked once. this is not a conclusive observation, as the thing is pretty hard to trigger at will, so only time will tell, but so far things looks quite promising. the patch in question is http://cgit.freedesktop.org/xcb/libxcb/patch/?id=b0525e242368fffbc77ebb45293f34e80847e65a dunno if it applies to anything else (in fact, don't know if anyone beside me has ever experienced this, but whatever), but here it is anyway. -- [-] mkdir /nonexistent -- To unsubscribe, send mail to [email protected].
