[SOLVED] Debian isn't booting

Pelycosaurus · 07-16-2016, 04:08 AM

When i try to boot Debian, it shows up this:

Quote:

Loading, please wait...
/dev/sda4: recovering Journal
/dev/sda4: clean, 287602/12197888 files, 9247031/4878128 blocks
[ 2.941650] systemd[1]: Job paths.target/start deleted to break ordering cycle starting with basic.target/start
[ 2.941731] systemd[1]: Jobb rpcbind.service/start deleted to break ordering cycle starting with basic.target/start

Then shows a login and that's it. When i login it's just a terminal. Is there any other way fixing this without reinstalling Debian?

I got this when trying to install CUDA when Blender could only render with CPU but not GPU, even though i had an Nvidia card. Then when restarting the system, that's when the error come up.

I was using Debian 8.5.

System specs (if required):
GPU: MSI GTX 970
CPU: Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz 3.40 GHz

How did you install the NVIDIA driver?
Please repeat the steps and let us know of any errors shown -- I realise you can't copy and paste but the errors ought to be obvious and please be as explicit as possible.

I followed these steps found on http://blender.stackexchange.com/que...ing-for-cycles

Please note that this is for Debian Jessie (8), the current stable. For instructions for wheezy, please see https://wiki.debian.org/NvidiaGraphicsDrivers

First, become super user by typing in su and entering in you password when it asks for it, or by preceding all commands with sudo (will still ask for password the first time), assuming you set it up.

Then type in:

nano /etc/apt/sources.list
And add the line deb http://http.debian.net/debian/ jessie main contrib non-free if it's not already there.

Then do an apt-get update, to refresh the package lists on the computer, then finally, install the drivers with:

apt-get install linux-headers-$(uname -r|sed 's,[^-]*-[^-]*-,,') nvidia-kernel-dkms
To finish up the actual driver installation, create an Xorg configuration file with the following commands:

mkdir /etc/X11/xorg.conf.d
echo -e 'Section "Device"\n\tIdentifier "My GPU"\n\tDriver "nvidia"\nEndSection' > /etc/X11/xorg.conf.d/20-nvidia.conf
Than reboot your computer to blacklist (disable) the open source nouvou driver which is loaded by default.

All that is required afterwards, is to install cuda with the following command:

apt-get install nvidia-cuda-toolkit

OK, so what errors did you see when installing? If none then you may need to run nvidia-xconfig as shown on the page linked to.

But how if Debian doesn't even boot?

Does it boot or not?
The command given is run as root from the terminal, please read the page linked to for more information.

Pelycosaurus · 07-16-2016, 04:46 AM

I'll try.

Pelycosaurus · 07-16-2016, 04:55 AM

Command not found.

Then you should have seen an error message upon trying to install. Did you? Try carefully following the steps on the page linked to.

# jessie-backports
deb http://httpredir.debian.org/debian jessie-backports main contrib non-free

# apt-get install linux-headers-$(uname -r|sed 's,[^-]*-[^-]*-,,')

# apt-get install -t jessie-backports linux-headers-$(uname -r|sed 's,[^-]*-[^-]*-,,')

# apt-get update

# apt-get install -t jessie-backports nvidia-driver

All of these are done.

Good! You have working nvidia driver then. Anything else we can help with?

Perhaps try installing nvidia-xconfig manually. I had thought it was part of the driver installation process but it may be that it is no longer.

Emerson · 07-16-2016, 06:24 AM

Code:

mkdir /etc/X11/xorg.conf.d
echo -e 'Section "Device"\n\tIdentifier "My GPU"\n\tDriver "nvidia"\nEndSection' > /etc/X11/xorg.conf.d/20-nvidia.conf

There is no need for nvidia-xconfig if the above is done.

Probably not but if the guidance was followe to no. Avail then it may work.
I'll be honest here -- I've the same. Card. Running under zisd fine with the NVIDIA drivers from the web site but my X11 configuration files are a few years old and I have an xorg.conf which seems to still be in effect.

Pelycosaurus · 07-16-2016, 07:13 AM

I believe i did some kind of xorg stuff when it stopped to work.
