[Ubuntu-x-swat] [Bug 454310] [NEW] karmic upgrade problem: boots to 
prompt and keyboard input very sketchy

Hi, not suer if posting this reply correctly, but here goes...

I had the same symptoms. It seems to be related to the Nvidia drivers 
having been built for the previous kernel. Booting into the upgraded 
karmic doesn't seem to provide the usual prompt regarding graphics drivers.

I worked around the problem by booting into recovery mode, and when the 
prompt of choices was presented, I chose to resume normal boot. This 
takes one to a text mode normal login session (not root). I then 
navigated to a subdirectory of my home directory, where I keep my source 
files. I then installed the Nvidia drivers as usual, with the line:

sudo sh ./NVIDIA-Linux-x86-185.18.31-pkg1.run

Of course the text would vary for whichever version is applicable.

If one doesn't have a copy of the driver on hand, one could boot into a 
live CD session, mount a suitable partition, and download to it. 
Otherwise, I suppose it would be possible to edit xorg.conf to use other 
drivers.

I can't clearly recall what I had done with my Nvidia drivers in the 
past, though I suspect I had removed the Ubuntu package which handles 
this automatically, in favour of manually installing the drivers from 
nvidia.com. I suspect the upgrade reverts to an ubuntu package to handle 
the drivers. I'm no expert though...
