Can't say it will make any difference but if an update seems to fail somewhere I run this sequence from a console -

sudo dpkg --configure -a
sudo apt-get update
sudo apt-get -f install

Hope it helps

Don't think the update failed. I guess I'll try that in the console after launching in recovery mode? I'll try and let you know, thanks

You're saying that booting an older kernel didn't help. Apparently you don't have a separate boot partition and your boot partition can't be full.

It sounds like something from the boot init (upstart, systemd?) got maxed up. There can be triggers that can easily cause the system to hang. It is not very failsafe. I once had a two minute boot delay because I introduced a network script that exited with error and the system demanded there be networking before it wanted to boot. Can you imagine that. A boot process that completely hangs (almost) because there is no supervising script that forces completion. The component that caused the hang was called failsafe.

Allright, manual updating from console was performend, but sadly it wasn't what was needed. However, while it was booting, I accidentally pressed the Down directional key, and something showed up. Sorry took a picture with my phone, hope the resolution is good enough, I really don't know how to read this http://imgur.com/a/a0B59

Second and third image are from the same boot, just showing different angles of it. In both cases, it never moves from that screen

@xennex81, I did the install a while ago, so I don't remember all the details and if I made separate partitions for boot and home, but I do remember that unless I fill up the boot partition, I shouldn't have problems... and I'm pretty sure I didn't fill it

NVIDIA GeForce GTX 850M

Nvidia drivers seem to be the source of a lot of 'blank/black screens'. Post the driver version and how you installed it (Ubuntu repos or manually after downloading from Nvidia) and you will likely get some help.

You could also run 'grep EE /var/log/Xorg.0.log' to see if it is Xorg failing to load the display driver.

I remember the process of installing the Nvidia drivers being long and painful, but I don't really remember what I did specifically... (I remember spending a lot of time looking for a way to "close the X server" or something like that. I am still a newb, after all...). I will look into my downloads folder, if I did indeed get it from Nvidia, it should be there

As for running that line, I can only do that after I do safe boot... but doesn't that mean that the drivers have definitively not loaded? I know the system does tell me that safe booting will not load most of them, and in fact I can only use 1 of my monitors through safe boot. I'll try that anyways (it's a lot of back and forth, since this is my only computer) and post results

Allright, after some fiddling around, I've run the line told, and got this https://www.dropbox.com/s/irchhaoweg...50.43.jpg?dl=0
Not sure what it means, but I see a lot of failed things

I've checked in the settings and under driver management software, and I have a choice between 4: NVIDIA binary driver (3 of them), version 340.76, version 346.59, version 349.16, or X.Org X server -- Nouveau display driver. Currently, NVIDIA binary version 340.76 is selected

(by the way, KDELibs version is 4.13.3, Qt Version is 4.8.6, Kernel version is 3.13.0-52 (and if I remember correctly, the previous installed one was -45 or similar). Not sure if this helps, but I found it, so I might as well post it here)

I've had a check in my download folder, but I haven't found trace of the NVIDIA drivers... I really don't remember how I installed them...

What's the next step? Thanks!

**ronw** · May 11, 2015, 11:11 AM

Hopefully someone familiar with Nvidia driver tricks will come along to help. I use the Nouveau driver.

I'm not sure if the GLX error in your Xorg log is significant, but it might be.

**xennex81** · May 11, 2015, 11:21 AM

It is so painful to be seeing this problem not be resolved easily. This display driver issue is pretty new to Linux I believe. I myself have installed the Intel Graphics Stack. I'm to the death afraid something will break after an update with no way to fix it, or not knowing any way.

**Qyvalar** · May 11, 2015, 11:47 AM

I tried changing the drivers from the driver management, to the latest NVIDIA ones, but that wasn't it either

I'm really stuck

**vinnywright** · May 11, 2015, 02:15 PM

I think for some reason the GLX part of the diver is not installed or working for some reason ,,,,,if you can,,,,,,I would do a

Code:

apt search nvidia | less

using less you shold be abel to scrole the output with the arow keys.

look for all installed nvidia components,,,,,,

Code:

sudo apt-get remove --purge <nvidia-driver-name>

,,,,,,then reinstall one

Code:

sudo apt-get install <nvidia-driver-name>

allso make sure you have the "dkms" package installed ,,,,,it should be ,,,but check .

ehm... apt search nvidia | less returned a lot of nvidia results... and I do mean a LOT. Am I supposed to individually remove them one by one? Because we're talking more than 100 here

I've tried to do the second step on one of them to see what happens, and it returns "Log file in use"... tho this might just be because I'm a newbie and I'm not really sure how to do it

I'm starting to consider a full reinstall... though I'm not sure it would fix it, at this point, considering I didn't have any problem before the update
