Hello, I had the same problem with my Dell XPS 1330 under Jaunty.
This problem did not happen immediately after the upgrade from Intrepid, but a
few days later, with apparently no reasons.
Both mouse and keyboard froze at login screen, and I was unable to make them
work by rebooting.
However, I resolved this problem. I am not really sure of the steps you should
follow because I made many many tries. I think that the following commands made
the miracle:
sudo update-rc.d -f dbus remove
sudo update-rc.d dbus defaults
sudo update-rc.d -f hal remove
sudo update-rc.d hal defaults
they reset the dbus and hal starting service defaults in rc.d
If these commands do not work, keep in mind that before executing them
I:
- reinstalled both dbus and hal
- reconfigured the xorg.conf to defaults with dpkg-reconfigure xserver-xorg
In addition, I was able to "unlock" mouse and keyboard at login screen
by adding the following lines to xorg.conf
Section "ServerFlags"
Option "AllowEmptyInput" "false"
EndSection
however, when logging in, a message told me that HAL could not be
started. I started it via console by typing
sudo /etc/init.d/hal start
and HAL started correctly, but mouse and keyboard behaviours were very
strange, e.g. by pressing a letter, I obtained the letter repeated
twice. After resetting dbus and hal runlevels I commented the three
lines added in xorg.conf without any error.
I hope that my post will be useful ;)
