OK, so as mentioned a while ago, we have this desktop that has no consoles for some reason. No VCs (no login prompts, but console messages appear fine ) and KDM won't start automatically. /etc/init.d/xdm start does nothing, but sshing in and running kdm works.
Well now shutdown does nothing but send the shutdown announcement, forcing us to hard-poweroff (yank power cable).
To make matters worse, we're trying to use it to write a bunch of USB drives for our customers and when run under sudo, our hard-drive populating script (essentially just partition, mkdosfs, tar -xzf image.tgz) locks the desktop, forcing a reboot (CTL-ALT-Backspace restarts X in a normal state, but the clerk didn't know to do that, and has left now)
Does anyone have any idea WTF is going on with this machine? |

Check you have gettys running, that you have the console device nodes, and you have VT support in the kernel (but normally it's not easy to remove it by accident, so that last one would be strange). You should have something similar to this:
| Code: | melanie ~ # ps aux | grep getty
root 9870 0.0 0.0 3620 4 tty3 Ss+ Sep28 0:00 /sbin/agetty 38400 tty3 linux
root 9871 0.0 0.0 3620 4 tty4 Ss+ Sep28 0:00 /sbin/agetty 38400 tty4 linux

root 9873 0.0 0.0 3616 4 tty6 Ss+ Sep28 0:00 /sbin/agetty 38400 tty6 linux
root 21574 0.0 0.0 3620 524 tty2 Ss+ Oct11 0:00 /sbin/agetty 38400 tty2 linux
root 6022 0.0 0.0 2676 508 pts/0 R+ 01:15 0:00 grep getty
melanie ~ # ls /dev/tty*
/dev/tty
/dev/tty0
/dev/tty1
...
melanie ~ # zcat /proc/config.gz | grep VT
CONFIG_VT=y
CONFIG_VT_CONSOLE=y |

If you have to do that, at least remount all the partitions read-only and run "sync" before you kill the power. It will limit the risk to the filesystems (journalled filesystems ensure that metadata will be consistent, but they do not protect data). |

Yup,
| Code: |
persephone etc # zcat /proc/config.gz | grep VT
CONFIG_VT=y
CONFIG_VT_CONSOLE=y
persephone etc # ls /dev/tty*
/dev/tty /dev/tty34 /dev/tty60 ...
persephone etc # ps aux | grep getty
root 15815 0.0 0.0 1500 464 pts/0 S+ 12:46 0:00 grep getty

and this is my inittab:

After upgrading to kernel 2.6.12.5, there is still no gettys and no KDM. If I manually run
| Code: |
agetty /dev/tty0 19200
|
or
| Code: |
//usr/kde/3.4/bin/kdm
|
It works. |
