Ubuntu 11.10 upgrade from 11.04

After the upgrade I ran into a few problems during boot up. The first one was an error during boot regarding vga=733 and gfxpayload. To fix this I changed a line in /etc/default/grub.
#GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash”
#GRUB_CMDLINE_LINUX=” splash vga=640″
GRUB_GFXMODE=1024x768x24,1024×768
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash”
GRUB_CMDLINE_LINUX=””
I suppose I only needed that one line.

GRUB_GFXMODE=1024x768x24,1024×768
And to comment out the line.
#GRUB_CMDLINE_LINUX=” splash vga=640″

Next I have to figure out why it stops booting at a line about pulseaudio. Dmesg has nothing about this error and in order to get to X I ctrl fn F2 and log in with my user, then sudo gdm start and it goes back to the failed screen and starts X.
Boot fails here
PulseAudio configured for per-user session
saned disabled; edit /etc/default/saned
Sometimes I would see a message about checking battery state, which led me to some posts about nvidia drivers causing similar problems. I have an Intel chipset so I figued this was a wrong answer. I did find some references to lightdm and gdm being part of the problem.
I uninstalled  lightdm “apt-get remove lightdm” and then reinstalled “apt-get install lightdm” this also removed and reinstalled ubuntu-desktop. A quick reboot and I’m booting into X with no visible errors unless I look in the logs.
