Public bug reported:
I replaced Ubuntu 11.10 with 12.04 64 bit beta on my brother's laptop 1
1/2 weeks ago. Everything worked perfectly until last night when I did
updates for him. Following the updates, which were listed as a Partial
Distribution Upgrade, upon rebooting, there was not any display after
entering the password during boot. It is an HP dv6910us laptop with
NVidia Geforce 7150M graphics. Unity and this computer worked perfectly
with 11.10, and also with 12.04 prior to last night. I've tried two
complete fresh installs. The recommended NVidia Driver, which is
presently 295.40-0ununtu1 is not installed during the install of 12.04.
In checking the NVidia site, this driver was just relesed 4/11/12. I'm
guessing that this driver is the issue, and it was updated from whatever
the previous recommended driver was during last nights install. NVidia
did say earlier on their site today that there were instances of it
causing Unity to freeze. If I boot in 2D, the system does funtion. If I
install the 295.40 driver when booted in 2D mode, it will not fix the
problem and I still can't boot in Unity 3D. Thank you for your help.
