Problem during upgrade to 10.10 on netbook

PS No messages were displayed on restart. Just straight to alternating screen.

Was able to restart into failsafe graphics mode and get desktop. Roll down menu does not work and neither does update manager. Obviously this is a graphics card problem.

ok can you give the output of:

sudo lshw -C display

Thanks

While in safe VGA mode, can you get updated. It may help.

If you log in as a different user, is it ok?

Update manager doesn't work but with terminal command apt-get update this is message:
W: GPG error: http://extras.ubuntu.com maverick Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 16126D3A3E5C1192

sudo apt-key adv --recv-key --keyserver keyserver.ubuntu.com 16126D3A3E5C1192

Will get that added. You added a PPA but not its key

Added this. Did apt-get update again; No error messages but am still in graphics failsafe mode.

Should I upgrade packages through synaptic package manager?

just run:

sudo apt-get update; sudo apt-get -y upgrade; sudo apt-get -y dist-upgrade

Should help

Do you have any logs in '/var/log/dist-upgrade/'? Looking over those may indicate more specifically what happened during the upgrade process. You could post the logs here or preferably, you could install pastebinit, then in a terminal type 'pastebinit -i /var/log/dist-upgrade/term.log' and finally paste the outputted url here.

Did what actionparsnip proposed and update worked. Now have fully functioning ubuntu 10.10 with the unity menu. Great stuff. So far everything seems to work fine. Only problem is at boot I get a udev error message which seems to be a common bug mentioned by many netbook users and is annoying but not necessarily serious. And start up is slightly slower than previous version of unbr. Thanks for all your help.
