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

The lspci: http://pastebin.com/qSbviUn1

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".

You need to disable Secure Boot in BIOS.

nvidia: module verification failed: signature and/or required key missing - tainting kernel

Nvidia driver does not load.

See this question for explanation.

  • The answer of Pilot6 is correct since you have an EFI motherboard which support secure boot by default. If you switch off `secure boot` you can load the driver and your security will NOT be diluted. – musbach Feb 19 '17 at 13:58
  • Secure boot disabled and still not working. I tried with nomodeset and surprisingly boot working: [adding nomodeset to grub options](http://askubuntu.com/questions/38780/how-do-i-set-nomodeset-after-ive-already-installed-ubuntu). I update main answer with this workaround, but I think there should be a better solution. – vpedrosa Feb 26 '17 at 13:15
