[Bug 518623] Re: VIA KM400: Black screen after boot, no text console possible

[gokul]

I tried to append to the information here but I got an error:
""
apport-cli -u 518623
Error connecting to Launchpad: 'NoneType' object has no attribute 'makefile'
You can reset the credentials by removing the file "/home/su/.cache/apport/launchpad.credentials"
rm: cannot remove `/home/su/.cache/apport/launchpad.credentials': No such file or directory
""
I have attached a tar archive of some manually run commands (dmesg, lspci, cat /proc/cpuinfo and Xorg.conf and Xorg.0.log files). Apologies if this comment is a headache(not filed with apport) rather than being helpful.

--------------------------------
My report:

My system shows the symptoms described in this report + some more.
---------
lucid kernel: vmlinuz-2.6.32-15-generic freezes and does not respond to alt+Fn combination -- even in the recovery mode.
I have tried removing plymouth. That did not help. 
---------
Using a karmic kernel "2.6.31-19-generic #56-Ubuntu SMP Thu Jan 28 01:26:53 UTC 2010 i686 GNU/Linux", I still get a black screen. But I am able to use alt+Fn in the recovery mode to get to a tty and work from there.

I have tried running "Xorg -configure" and tried using the new
configuration(attachement xorg.newconf + Xorg.0.log.newconf), It did not
help. But I was able to use the alt+Fn combination again and was able to
send a 'ctrl+c' to the "X -c /usr/sbin/xorg.conf.new" command.

But when I run X -c /etc/X11/xorg.conf (attachment xorg.origconf + Xorg.0.log.origconf):
* I lose keyboard control (using a alt+sysrq+REISUB did not help).
* Doing a "kill -9" of X's pid, did not restore keyboard control (numlock led does not toggle for example)
* vncsession still works fine (this comment was added from there.
