Details

Description: I'm running xdm as my display manager and display an xclock as part of my login screen. The Xstartup script kills this xclock using xkill. After upgrading libxt from version 1.1.1-2 to version 1.1.2-1, xkill still kills the xclock window upon login, but the process sticks around, spinning one of my cores at 100%. On another machine, I'm also showing an xmessage window as part of my login screen. In this case, both the xclock and xmessage windows get killed, but the processes remain and spin the CPU at maximum load. Downgrading to version 1.1.1-2 fixes the problem. So there is some regression in the transition from 1.1.1-2 to 1.1.2-1.


Additional info:
* package version(s) libxt 1.1.2-1
* config and/or log files etc.


Steps to reproduce: I guess the easiest is to install the xdm-archlinux theme and configure xdm to use it. Then login as an arbitrary user.
This task depends upon

Does a rebuild of xorg-xkill fix it? If not please report it upstream.

Is this applicable?

Hm. Maybe our LDFLAGS break something here. Can you try to rebuild it with LDFLAGS unset or something similar?
Comment by Norbert Zeh (nzeh) - Monday, 12 March 2012, 04:40 GMT
Recompiled xkill and libxt with the LDFLAGS unset. This didn't change the behaviour. So I guess I'll go and report it upstream.

Possibly this is related: https://bugs.archlinux.org/task/28875

Can you try recompiling libxt with the commit reverted?

Recompiled with the commit reverted. Well, actually, I didn't want to create a PKGBUILD that pulls from git and reverts the patch, so I simply manually reverted it. No more CPU spinning by xclock, xmessage or xscreensaver. So I would think that patch is the culprit.

Please test, if libxt 1.1.2-2 solves it for you.
Comment by Norbert Zeh (nzeh) - Monday, 12 March 2012, 20:27 GMT
Yup. 1.1.2-2 solves the problem. Kudos, guys - you rock.
