Graphics not working after upgrade

[trikrasne]

I can't log-in in graphic mode after upgrading Ubuntu. I can only log-in via terminal.

These are some errors reported after booting the vomputer, just before the login-screen.

Can you test the kernel in the -proposed repository?

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

Thank you in advance!
