I have also update the X package to 7.4 (87.1) The difference is that with lxde desktop default settings the background process in the screensaver blocktube. NOTE: strace indicates the first errors showup in the X process, then xscreensaver child then blocktube then child. strace indicates kdm and lxsession processes don't have read errors. So, as far as I can tell the problem lies within the X system. Note that the background desktops 'blocktube' screen saver occassionally crashes, and I have attached the strace of such a crash. # rpm -qi xorg-x11-server Name : xorg-x11-server Relocations: (not relocatable) Version : 7.4 Vendor: openSUSE Build Service Release : 87.1 Build Date: Mon Nov 2 20:24:48 2009 Install Date: Thu Nov 5 15:34:31 2009 Build Host: build34 Group : System/X11/Servers/XF86_4 Source RPM: xorg-x11-server-7.4-87.1.src.rpm Size : 3922024 License: GPL v2 or later ; MIT License (or similar) Signature : DSA/SHA1, Mon Nov 2 20:26:03 2009, Key ID bb1af2330f2672c8 URL : http://xorg.freedesktop.org/ Summary : X.Org Server Description : This package contains the X.Org Server.
