I have been facing the same issue and is very annoying having to hard reboot everyday. Can anyone update when this is to be resolved. I am planning to downgrade in case it takes too long for this issue to get resolved.

Titan (firuzvanquisher) wrote :

@Renu Kumar: You can log in into `Ubuntu Classic` when login screen appears.
That would help.

Shimi Chen (shimi-chen) wrote :

Can you be more specific on the workaround?
Are you logging in to the Classic session or Classic(no effects)?
Does this solve the hangs completely or does it make them less frequent?

@Renu Kumar
Can you run this command and post the terminal output:
lspci -v -s `lspci | awk '/VGA/{print $1}'`
So that it will be noted what sort of graphics card you have(in particular if the same one as Titan).
Also, post weather or not Titan's workaround helps stop hanging on your computer.

logging in to Classic session (not Classic(no effects)), now ubuntu rarely hangs(say once in a couple of weeks).

Titan: Is there any other information you can provide as to what caused the hangs? It is extremely difficult to fix bugs without a reproducible way to make it happen.

titan, did you also test with Ubuntu Classic session to see if the problem is specific to Unity or a general regression in Oneiric.
