--9RXjJcDGNuBviZqz Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable In the last month or two I've seen increasing occurrences of programs refusing keyboard input after they've been running for a while (between hours and days). They still respond to the mouse. At first I thought it was hardware, but it happens on a number of different machines, and only with certain programs, all of them X clients. Here's an overview (system names are simply to show that they're different machines). - System echunga, running a version of the klondike game that used to come with the X distribution. - System wantadilla, running firefox. After it refuses keyboard input, I can open a new window with the mouse, and the new window accepts input. The old one still doesn't. - The same problem again with system teevee. wantadilla had what I think were hardware problems a couple of weeks ago, so I changed the entire system board and memory (but kept the disks). The new system is stable, but the problems continue. echunga and teevee have been up for months: echunga up 49+02:25, 1 user, load 0.60, 0.50, 0.35 teevee up 100+22:08, 0 users, load 0.06, 0.31, 0.28 tvremote up 36+21:07, 0 users, load 0.18, 0.04, 0.01 wantadilla up 18+02:44, 3 users, load 0.46, 0.38, 0.49 One thing that the machines have in common is that they all run x2x (which joins X servers). echunga and wantadilla run one instance, and teevee runs another instance with tvermote, which I don't think has shown any problems. I've been running x2x for years as well, and only one of the machines has had a software upgrade anywhere near the time when the problem began. Here are the versions: FreeBSD echunga.lemis.com 6.1-PRERELEASE FreeBSD 6.1-PRERELEASE #0: Sun Feb= 5 14:15:02 CST 2006 grog@echunga.lemis.com:/usr/obj/src/FreeBSD/6-STA= BLE/src/sys/ECHUNGA i386 FreeBSD teevee.lemis.com 5.3-RELEASE-p5 FreeBSD 5.3-RELEASE-p5 #4: Sun Mar = 13 14:58:24 CST 2005 grog@teevee.lemis.com:/usr/obj/src/FreeBSD/TEEVEE/= src/sys/TEEVEE i386 FreeBSD tvremote.lemis.com 5.3-RELEASE FreeBSD 5.3-RELEASE #0: Fri Nov 5 0= 4:19:18 UTC 2004 root@harlow.cse.buffalo.edu:/usr/obj/usr/src/sys/GENER= IC i386 FreeBSD wantadilla.lemis.com 6.0-CURRENT FreeBSD 6.0-CURRENT #1: Tue Jul 12= 11:57:56 CST 2005 grog@wantadilla.lemis.com:/usr/obj/src/FreeBSD/6-CUR= RENT/src/sys/WANTADILLA i386 Does this ring a bell with anybody? Any idea how to start debugging? The fact that new firefox windows accept input suggests that it's somewhere in X.
