Bug Description
SRU justification: late-cycle regression that causes users who have encrypted root filesystems configured to be unable to see the password prompt with certain hardware, unless they switch VTs to toggle the video mode.
TEST CASE:
1) install a system with an encrypted root filesystem using the 11.10 alternate or server ISO.
2) verify that on affected, KMS-capable hardware, the passphrase prompt is not displayed at boot, but that it is displayed if you hit Alt+F6 followed by Alt+F7.
3) install initramfs-tools 0.99ubuntu8 from oneiric-proposed
4) reboot 10 times on the affected machine, and verify that the passphrase prompt is correctly shown in each case.
5) verify that with this version of initramfs-tools installed and cryptsetup and nvidia-current packages installed on nvidia-capable hardware, that there is no regression in the display of the plymouth splash screen at boot time vs. the previous version of initramfs-tools.
When booting the plymouth splash screen is shown for a second and then the screen goes blank.
I have an encrypted the root partition so this makes it a bit difficult to input the password.
Entering the password after some time when the screen is blank works fine though.
Switching the VT with ctrl+F6, ctrl+F7 shows the plymouth password promt again but it's very distorted.
Possibly a duplicate of bug #816267

Hi Felix,
A few things for you to try:
- does hitting 'esc' once instead of Alt+F6/Alt+F7 fix the issue?
- does hiting 'esc' *twice* fix the issue?
- does hitting Alt+F7 *without* hitting Alt+F6 fix the issue?
- what do you see if you boot without the 'quiet' option (but still with the 'splash' option)?
Finally, please add the options 'drm.debug=0x4' and 'plymouth: debug=file: /var/log/ plymouth- debug.log' to your kernel commandline, and attach the resulting plymouth and kernel log files.
