Due to bugs 473001, 473002, I wanted to give up on NetworkManager (NM) and fall back to old-style network configuration e.g. system-config-network (s-c-n), ifcfg-eth*, "service network start", etc. So, I did this: * Validated that /etc/sysconfig/networking/profiles/default/* had sane content. * chkconfig NetworkManager off * chkconfig network on * reboot Now, for some reason, X startup is predicated upon NM running (or something like that) and now X won't start, so I had to switch back to running NM. I don't know if this is an upstart bug (i.e. system-wide config/event scripts shipped as part of upstart), or an X bug (i.e. upstart config shipped with X), or some other package. Hence, starting this bug off against upstart; please re-assign as appropriate. Thanks!
Upstart's handling of these bits is very second-hand, so I don't know that we're causing it, but I'll keep the bug until I can sit down and test it personally.
What is the failure you're seeing in X?
I think it simply doesn't attempt to start; when the boot "completes", I'm left starting at a text-mode screen (I have an NVIDIA card, so no KMS) that's blank, with just a blinking cursor. I can change VT to some other and log in text-mode just fine. The text-mode startup splash thing works fine during the boot process.
What's the output of 'initctl status prefdm'? Is there anythign in /var/log/Xorg.0.log of interest?
I can no longer reproduce this; I can boot to X just fine without NetworkManager now. I'm not sure if my original issue was some strange one-off issue. Perhaps it's something I did to make NetworkManager work that I'm not reverting correctly when attempting to repro this issue.
OK, closing.
