Hello, I have several CentOS 6.2 hosts (2.6.32-220.7.1.el6.x86_64) that lock up when attempting to use the Gnome desktop from the console. I can always log in, but then all I get is the blue root window, the round initial mouse pointer, and nothing else. The last process associated with the console is "xprop -root" which strace shows as hanging indefinitely. There are cases (sporadic, unpredictable) when I get further; the screen contains desktop icons, the menu at the top, and an arrow mouse pointer, but the mouse and keyboard don't work. I can reproduce this behavior frequently by setting the system run level to 3, logging into the console, and running "strace -f startx". One other bit of information: I build all the hosts with the same kickstart file, and most of the hosts work fine; only a handful are acting up. Has anyone seen this before and/or know how to troubleshoot it? Thanks, Jack
