Ubuntu 12.04 can't boot after hardware support update

Ok, keep in mind this is all foreign to me -- never even heard of the HWE before your post.

Re-read that HWE link and think I have slightly better understanding of it.

My guess is that you upgraded the kernel, but the graphics stack to go with it did not get upgraded yet which is now the reason you can't start the GUI interface.  (I could be way off base on this guess.)

Boot up into Ubuntu tty and try running the command for the HWE status.  Don't know if you need to run with sudo or not, try w/o sudo -- if doesn't work use sudo.

Code:

hwe-support-status --verbose

Or

Code:

sudo hwe-support-status --verbose

I have no idea what you will see running that, but the HWE link said that if you didn't have the graphics stack installed it would inform you how to proceed with that.  Go ahead and see if that helps.  If confused by instructions shown after running command, try to write down what is shown and post back here with that.

Good luck!

P.s. Since you tried deleting the new kernel, running above command may try to reinstall it.  Go ahead and let it do that if you don't see an option to fix graphics by itself.  Maybe it will fix graphics at same time.  If after reinstalling new kernel, still won't boot in GUI -- run command again to see if it now offers graphics fix.
