Fedora 9 Beta Live CD: disabling services during interactive startup
Oisin Feeley wrote:
The i686 FedoraDesktop LiveCD appears to fail somewhere after
NetworkManagerDispatcher is started. The exact symptoms are that the
screen flickers, goes blank and the CD drive continues to spin for
minutes and then becomes inactive. Keyboard or touchpad input results
in the CD drive spinning up again but the screen remaining blank.
Attempts to see what's going on by switching to some other console via
Alt-Ctl-Fx appear to be ignored.
Attempts to selectively disable services (with the object of disabling
NetworkManager and NetworkManagerDispatcher) are a problem because the
reading of the options appears to ignored. The prompt "<service name>
(C)ontinue/(Y)es/(N)o" (or something of that form) appears, but it's
necessary to enter at least two carriage-returns with the option, a
bit of what appears to be Python code for reading the option and
starting the services is printed and then the service is (possibly)
Do these messages look like something is wrong with your keyboard input? Do you
have a typical US layout keyboard or something else? That sounds very much like
garbage is getting sent to the script rather than understandable bytes, and its
going 'oh crap' when it cannot find a Y or N.
So, any ideas as to how I can get a bit further with testing the
pre-release? Or capturing better info for reporting whatever is going
wrong to bugzilla?
You can boot the machine to runlevel 1 or 3 by editing the syslinux boot menu
before it starts the automatic boot. That should let you disable NetworkManager
or NetworkManagerDispatcher to see if those are the culprits. You can also
adjust/edit X configuration from there if necessary before starting gdm to login
(in runlevel 5).
Push TAB while looking at the boot menu, then add a '1' or '3' at the end of the
kernel parameters and push enter. You can do anything from those runlevels that
a typical installed machine would allow you to do, mounting a flash drive to
copy off debug logs for instance.
