I used the first command to prevent xwindow from starting, this prevented my sound from working after a reboot.

So then I used the command posted to restore it back to bring up the regular login and now my mouse and keyboard no longer work, the login screen comes up and I can type nothing and can’t move the mouse around.

I am currently running off the live CD…. anyone know a fix for this so I don’t have to reinstall? Please any help would be appreciated.

Bernhard is right: S30gdm K70gdm work perfectly using bum boot-up manager.

“update-rc.d foo defaults” will not put “foo” back into its previous start-up slot, but puts it at S20 by braindead “default”. Its the oldest surviving bug in UNIX history. For gdm this can cause real grief cause it puts it before processes that should have completed start-up before gdm goes about its merry ways.

Better solutions:
use mv to change the symlink in a particular runlevel to K(100 minus Svalue) e.g. “mv S30gdm K70gdm” and when you want it back in use “mv K70gdm S30gdm”. Better yet, use a dedicated boot-up manager (e.g. “bum” which has a friendly GUI) to edit your runlevels.

update-rc.d is full of inconsistencies and hidden traps.

I’m just a novice, but enjoy the info on your site. I’ve done everything in windows since 85 and have really forgotten everything dos…its been so long ago. Really like this unit with Ubuntu and the ability to go to the command line. The commands are new to me, but hopefully I can get up to speed and learn some real computing.

Peace, Paddy
