Hello!

You have given us precious little to go on, here.

Which release are you using?

What are your hardware specs?

Were you using any proprietary drivers?

We're all here to help, but we need to know what we're working with.

[pixelro]

oh, sorry :>

Ubuntu 14.10, proprietary Nvidia drivers, amd64.

[pixelro]

so, since i have nothing better to do (i'm on a live cd, +chroot waiting for updates) how can i debug it? i can't get to tty because the keyboard locks

On my system there is a kernel update waiting to come down. Perhaps you have already had the update. Boot into an earlier kernel. Or use recovery mode>Resume. If that gets you to a desktop then use Additional Drivers to change video drivers. Use recovery mode to update/upgrade. There might be a fix in the next update.

Of course a lot depends on where you get the black screen. Which you do not tell us. So, all I can add is, thank for the information. I will avoid updating for the next day or two. Actually, it does not matter if I get a blackscreen because I have other installs of Ubuntu to boot into.

Regards.

I too am experiencing this on my laptop (nvidia driver) I have removed nvidia* & purged out all nvidia drivers & now it allows me to logon but then dumps me back to a terminal.

I too have the same issue as pixelro. 14.10 and Nvidia too.

ii nvidia-304 304.123-0ubuntu2 amd64 NVIDIA legacy binary driver - version 304.123
ii nvidia-current 304.123-0ubuntu2 amd64 Transitional package for nvidia-current

unity --version
unity 7.3.1

All was well this morning but not now after latest upgrade about 20 minutes ago.

Same issue here, NVIDIA as well.

After dropping to a root shell and trying startx from there, it refuses to start because "no screen found".

[pixelro]

it's not the kernel, the kernel didn't update because it didn't prompt me to restart. Also i've tried older ones with the same result. The system freezes after the login screen (text) i don't see any graphics. keyboard locks and the screen is black :>

Okay... in my Xorg.0.log I'm seeing:

[   106.444] (II) LoadModule: "nvidia"
[   106.444] (WW) Warning, couldn't open module nvidia
[   106.444] (II) UnloadModule: "nvidia"
[   106.444] (II) Unloading nvidia
[   106.444] (EE) Failed to load module "nvidia" (module does not exist, 0)

Finally this:
