Mouse _seems_ okay, but I'm not sure if I'd notice lag there. > that mouse is OK... Hmm, what happens if you load evbug and type while > watching syslog. Do you observe the same delays? Hmm, seems that it only happens in X... so maybe it is some strange scheduling artefact? Hmm, something is wrong here: On console, I get expected 4-5 ticks a second. In x in gnome-terminal, I get this: [EMAIL PROTECTED]:~# while true ; do echo -n . ; sleep .2; date; done .Tue Mar 20 17:28:34 CET 2007 .Tue Mar 20 17:28:35 CET 2007 .Tue Mar 20 17:28:35 CET 2007 .Tue Mar 20 17:28:35 CET 2007 .Tue Mar 20 17:28:36 CET 2007 .Tue Mar 20 17:28:36 CET 2007 .Tue Mar 20 17:28:36 CET 2007 .Tue Mar 20 17:28:36 CET 2007 .Tue Mar 20 17:28:37 CET 2007 .Tue Mar 20 17:28:37 CET 2007 .Tue Mar 20 17:28:37 CET 2007 .Tue Mar 20 17:28:37 CET 2007 .Tue Mar 20 17:28:38 CET 2007 .Tue Mar 20 17:28:38 CET 2007 .Tue Mar 20 17:28:38 CET 2007 .Tue Mar 20 17:28:39 CET 2007 .Tue Mar 20 17:28:39 CET 2007 .Tue Mar 20 17:28:39 CET 2007 .Tue Mar 20 17:28:39 CET 2007 .Tue Mar 20 17:28:39 CET 2007 .Tue Mar 20 17:28:40 CET 2007 .Tue Mar 20 17:28:40 CET 2007 .Tue Mar 20 17:28:40 CET 2007 .Tue Mar 20 17:28:40 CET 2007 .Tue Mar 20 17:28:41 CET 2007 .Tue Mar 20 17:28:41 CET 2007 .Tue Mar 20 17:28:41 CET 2007 .Tue Mar 20 17:28:42 CET 2007 .Tue Mar 20 17:28:42 CET 2007 So sorry for false alarm, it is not keyboard related, it is just very very strange.
