[mdlug] Ubuntu 12.4 on Lenovo laptop would not boot up after software update

[Michael Mikowski]

Oh, one more thing:  I'd be curious to see if a fresh-install and then update works.  The 11.4->11.11->12.4 chain probably has left a lot of legacy boot stuff in place.  If it is an option, a fresh-install might be something you'd want to try (perhaps on a separate partition or a spare 2.5" hd/ssd lying around the house).

Also, booting off a live 12.04 cd might and inspecting the options used there might (if it is possible) be instructive.

Again, best of luck.

Subject: [mdlug] Ubuntu 12.4 on Lenovo laptop would not boot up after software update
 
Hello,

I have Ubuntu 12.4 (originally Mythbuntu 11.4 upgraded to 11.11 and
12.4) on an old Lonovo R61 laptopwhich has been running fine (albeit a
little slow) for some time.

Today I did a suggested software upgrade and it does not boot since
the upgrade. It goes through the grub  menu and after I hit <enter>
the screen goes blank. I tried 'Previous Linux versions' to choose
earlier kernels but they all seem to work. I also tried to get to
consoles but <Ctrl-Alt><F1>... <F6> does not bring up any login
prompt.

I ran the memtest and it seems to run fine as well.

Any ideas?

Thanks
