I have got a problem after upgrading my graphics card: Ubuntu freezes on startup.
I reinstalled Ubuntu from 16.04 live cd using nomodeset and acpi=off, and then I tried to use the system normally, installing latest Nvidia drivers (nvidia-370, v370.28 currently), but freezing still happen. The freeze starts on ubuntu loading screen, with the dot animation. At some point it freezes, then reboot and black screen (and keyboard caps & bloqnum lights party).
I managed after a couple hours to boot, via Ubuntu advanced boot>Fail safe boot on grub, then pressing Ctrl+Alt+F1, then Ctrl+C, and it starts normally.
I tried older and newer drivers, nouveau and so, but it didn't work.
Here you have the Xorg.failsafe.log: http://pastebin.com/UdBQR4Pr

And the dmesg: http://pastebin.com/SSpTPBXn
Thank you very much.
UPDATE (12/02/2017):
Still not working with NVIDIA drivers 378.09 and ubuntu 16.10, fresh install, same errors.
UPDATE 2 (26/02/2017):
Disbled secure boot and still doesn't work, but found that adding nomodeset option to grub do the workaround and let it boot "normally".
