After the last update i get a black screen

[pixelro]

boot.log

* No suitable module for running kernel found
* Starting VirtualBox kernel modules [fail]
* Starting load fallback graphics devices [fail]

[caryb]

Strangely even after removing the Nvidia driver it then borks loading nouveau driver even on older kernels

[pixelro]

same here

[ScislaC]

Also worth noting that the shutdown and reboot commands aren't working for me either.

Also worth noting that the shutdown and reboot commands aren't working for me either.

I also have the same problem after today update, and I have nvidia drivers.

Tested Caps Lock, nothing.
Tested Alt+SysRq+B = reboot works

[Wise Ferret]

Very similar issues here, with nvidia gtx-770. If I remove every nvidia package I do manage to get Nouveau driver runing, but when the proprietary drivers are installed they fail to load and I can get only extremely low resolution.

[Elfy]

I removed nvidia and reverted to nouveau before rebooting after kernel update. Booted fine to the desktop, reinstalling nvidia afterwards and it's not getting loaded so still using nouveau here (xubuntu)

[harry332]

Surely this is a kernel module issue.
The installed newest linux kernel (3.16.0-11.16) will cause nvidia kernel module build to fail.
Thus X cannot be started.
Also see the bug reports #1362957 and #1362848.
Purging nvidia drivers will remove all kernel mudules, also from the older kernels.

You should try this.
- cold boot your system, as it does not get to Display manager, press ctrl+alt+F1 to get to the tty1 (console).
- log in
- purge the newest kernel (3.16.0-11.16), all the packages including the meta ones. Do not remove older kernels though! The latest working kernel is 3.16.0-10.15
- purge nvidia drivers, for example nvidia-331
- install nvidia drivers back (nvidia-331)
- reboot your system

i know its no help, but just to add...i did a clean install about a month ago, and promptly installed the latest development kernel (at the time i think it was 3.16-rc6) after a few days updated to 3.16-rc7. when 3.17-rc1 was released, i installed that and when i confirmed it was working properly i went and removed all default kernels, keeping only the development rc releases installed. i also have nvidia card with proprietary drivers installed (331.89)

as such, i do not have these issues with the latest updates. everything here is working fine with kernel 3.17-rc1....in fact boot up times are faster then ever with systemd:

systemd-analyze
Startup finished in 2.990s (kernel) + 6.565s (userspace) = 9.556s

[christopher9]

Just lucky I guess....I'm not experiencing any issues with my setup after updating to 14.10 and using proprietary Nvidia binary driver 331.89:
