Bug Description
During the boot of Lucid alpha 3, the monitor loses signal after the grub menu, and before KDE starts, dropping into standby mode and displaying "no signal".
Video card is nvidia GeForce 7300 GS.
The install was with an encrypted drive, meaning the passphrase prompt is never seen by the user, or any other user input prior to the KDE login prompt.
Turning off quiet and splash in grub has no effect. Using "nomodeset" shows the boot process, and the query for the passphrase, but won't boot KDE. x fails to start in that condition, and logins to the console take over 30 seconds to respond with a prompt. startx also fails with errors.
The 64 bit alternate install of Lucid alpha 3 actually completed successfully, but booting into the actual system requires me to wait until disk activity halts, then I wait a little more to make sure the prompt for the passphrase is settled, and then I enter the passphrase to a blank screen, and then KDE will come up. The monitor gets a signal when KDE starts, but not during the booting of the kernel.
With my system, any kernel boots of Lucid alpha 3 [liveCD, installs without encryption, installs with encryption] using the graphical boot system results in a period of monitor standby. Only when KDE starts does the monitor resume.

monitor drops to standby with "no signal" during boot splash on luicd - alpha 3 |
I just tried the i386 LiveCD of Kubuntu 10.04 alpha 3.
Starting with a normal livecd boot, the 'ubuntu' splash screen shows up without any loss of signal to the monitor. After a while, there is a small transition where the monitor goes "out of frequency", possibly due to testing settings. Then KDE appears and all is well.
With the "quiet splash" options removed, the splash screen does not appear, and the monitor does go to standby with the "no signal" message. This happens after the initial 4 or so seconds of the boot process appearing on the screen, which then flashes a green background, and then goes blank. This is when the "no signal" message appears on the monitor. After it continues through the boot process, the 'ubuntu' splash image shows up briefly, just before the "out of frequency" message, and then KDE appears. The monitor is in standby about 15 seconds.
I have tried both the DVI and VGA outputs on the video card, and both times the results were the same. I tried both at the same time too, and both monitors responded identically.
