I have not tried this for some time. The symptoms are somewhat
different.
I have rebuilt my complete system since the last time I caused a hang.
This was because of the elf and egcs changes. I rebuilt all ports,
including X. I learned to not touch the keyboard during the end of
session transition.
Now, the X session will start. But, CTL-ALT-Fx just beeps.
Everything with the X session seems OK.
I start X from /usr/local/etc/rc.d/xdm.sh, included below. I use the
xsm session manager. If I select xsm->shutdown->immediately with the
mouse, the session ends. The video mode changes:
1. The screen blanks.
2. A seemingly low-resolution color display is presented with some
bars across the top 1 cm of the screen.
3. The login prompt is presented.
Previously, during the video mode changing, during #1 or #2 above, if
I used CTL-ALT-Fx, the keyboard would hang. I would have to telnet
into the system and restart things manually. I killed xdm, restarted
getty, and, restarted xdm. This fixed things.
I can telnet in to the system. 'kbd_mode -a' does not change the
keyboard action.
The NumLock, CapsLock and ScrollLock led's do not change state.
I can not switch out of the X mode using CTL-ALT-Fx, it just beeps.
I will try to restart getty to see if it recovers. I will send the
results of this in a few minutes.
