Bug Description
Binary package hint: xserver-
I have upgraded my Xubuntu karmic installation to lucid to test the alpha release of lucid. After the upgrade, which went smoothly, I rebooted the machine. I expected to see the GDM login screen eventually, but all I got was a completely black screen. Even the backlight of the LCD panel of my laptop was off. Pressing the (CTRL+)ALT+Fx key combinations did not (visibly) result in a change to the virtual terminal that corresponds to the F-key pressed.
When I rebooted to use the recovery mode/single mode, I found that I couldn't get a text console even then. I was able to log in via SSH, which works perfectly and allowed me to run apport-cli from this machine. Furthermore, I could get a full graphical desktop by using vnc4server on this laptop and a vnc viewer on another machine, which confirms that the install is basically working. Therefore, I'm guessing that it has to do with the X server or driver, also because I've had some graphics-related trouble with this particular chipset that is inside my laptop before (VIA KM400).Still, it also might be due to this new boot splash method ubuntu is apparently using, but I'm not sure. (EDIT: changed 'Affects' to plymouth package. Have removed Xorg but still no TTYs)
WORKAROUND: blacklist both viafb and vga16fb.

- VIA KM400: Black screen after boot, no text console possible + [KM400] Black screen after boot, no text console possible |
After some research on launchpad, it seems more likely to be a bug in Plymouth than in xserver- xorg-video- openchrome. Moreover, I've completely removed Xorg and I still can't log in on a TTY
