You have been subscribed to a public bug: I originally guessed this is an xorg bug. Now I suspect it's a hardware autodetection bug, or something more serious in the reinstall routine when you don't format the target partition.
It seems major to me and so I'm really surprised I can't find reports of it against my hardware signature, so could be something distinctive about my system (strongest candidates : I have an updated BIOS, and was installing without reformatting the root partition). On Friday I upgraded from Karmic (working pretty well) to Lucid (was hogging CPU somehow) on a Lenovo Thinkpad T400. Because the system was so starved of resources for some reason, I thought I'd run a fuller rebuild without preserving any of my Karmic system. It's fairly understandable that the upgrade failed since I tweak my build a fair bit. I moved /home into /oldhome, and ran an install off the Lucid livecd without formatting / I understood this should replace all my system files and give me a clean home folder to recover my files into. The sequence I experienced was... LiveCD booted and ran fine, with good video resolution. Installer completes but on boot reports it can't load modules.dep Normal boot causes screen to flash active and inactive (but still black) several times, followed by thin red lines at the top and culminating with large white broken bars filling the lower eighth of the screen. After this I get nothing, no Xorg and no Gnome. Changing boot options to vga=771 noapic noacpi doesn't help get a usable system - same result. CTRL+Alt+F1 drops me back to a console, but after login warns me that it couldn't handle the home folder decryption (I don't know if this is connected) and indeed /home/cefn contains just a README about ecryptfs. My lingering suspicion is that even though I did a clean rebuild, there's something about the rebuild process which isn't REALLY clean, unless you format the drive and trash all the data on it. I wanted to keep the home folder intact on the partition as a backup renamed to /oldhome. I have a copy of the important information from it, but I suppose my only option now is to create a second backup and trash the partition properly, though why this would make any difference I don't know. I speculate that some routine fails spectacularly and invisibly during the install and causes many other critical things not to take place (e.g. login doesn't decrypt my home folder).
