[SOLVED] Dell Isnpiron 7759 Centos 7 no login prompt or black/blank screen

ladam · 01-01-2018, 10:58 AM

Hello ALL!

I'm having a problem, with Centos 7. On an older notebook, Im using CentOS without any bigger problem. After the testing I've installed on Dell Inspiron 7559 laptop. Installation ready and reboot, accept license. When I boot the computer choose the kernel in GRUB -it doesn't matter normal or rescue- blank/black screen or just grey background but without login prompt. I've tried to change to terminal window with Ctrl+Alt+(Fn)+F2 -Fn I've tried with and without Fn- but not responding. The GUI is gnome, VGA -Hybrid-: NVIDIA® GeForce® GTX 960M and Intel HD Graphics 530 GT2Any idea?

It sounds like maybe a driver is not working correctly for you. I can't say that for sure, but I think it's a good possibility none the less.

Have you tried hitting ESC to try and clear the splash screen?

As this may enable you to see any error messages related to the issue(s), your having. Please try that and report back.

(if any error messages - post them using CODE tags.)

Hello,

I've tried hitting ESC I've got the following messages:

The problem is with the nouveau driver supplied by Xorg used with Nvidia optimus graphics.
At the Grub prompt you need to hit the "e" key to edit boot parameters and add "modeset nouveau.modeset=0" without the quotes to the kernel line. Typically there should already be the word quiet in quotes, leave the existing quotes and add a space after the word quiet then the stuff in blue written here.

After that you can hit the F10 key to boot it, once booted up you can edit /etc/default/grub file, probably as root or sudo, to add it permanetly, or install Nvidia primus or whatever is required by Centos for that graphics setup, or you need to do this every boot. An example of the /etc/default/grub file with this argument is in the code box below. After adding this to the /etc/default/grub file, you need to run the two commands in the next code box below as root or sudo and it should boot normally every time after.

An example of the appropriate section of /etc/default/grub with the argument added:

Code:

GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet modeset nouveau.modeset=0"
GRUB_CMDLINE_LINUX=""

Code:

update-initramfs -u
update-grub

As for which packages you need to install to get the Nvidia proprietary graphics drivers, someone else will have to guide you. But you don't have to if you don't want to, you just won't have optimus capability (switching between Intel and Nvidia graphics)

Thank you!

I've tried "nouveau.modeset=0" that worked. But now I'm fighting with the nvidia driver installation. Based on this site but this didn't work. I think the problem is with the two vga card. So before I install the nvidia driver should I install the bumblebee? Which is the nvidia optimus on Linux.

Thank you again!

Try the nvidia driver first.

Add this repo to your repo list and install the driver from there.

Let us know if you need anymore help. Good luck with it.

Hello,

first of all thank you for supporting me. I've found this site, -I prefer this because newer drivers are there-, but isn't clear how do I install it. Although, at the bottom of the page 3 steps how to do. But it's not clear for me. When I try to install it always missing something... Thank YOU!

It looks like that's just a copy of the "ELrepo" site rpm package, that I linked you to in my previous post. It should just be a simple matter of adding the "elrepo" repository and running the yum command to install the nvidia driver.

See this to add the repo and then run the following command:

(scroll down to the "Get started" section)

Code:

yum install kmod-nvidia

Hello I've installed the packages. I've seen the nvidia x server in the utilities. Asked me to run as root the following command: nvidia-xconfig. After this I've restarted the system. It seems everything loaded I see the command window [OK]-probably do you know what I mean- but stuck. It seems everything started, but stuck, before I'd get the GUI...

So, when you say "stuck", what do you see exactly?

Also, what was displayed when you ran the "nvidia-xconfig" command? Did you run it?

Can you post the output of it?

I can't remember what I saw after nvidia-xconfig running. But the last row when writing what start:

Code:

Starting GNOME Display Manager...creen to Quit...........T) Daemon...r progress polling.

before gnome splash if you hit escape that is also looks like I mean like this I hope its clear what I mean.

jsbjsb001 · 01-18-2018, 11:45 AM

Thanks for the extra information. It's clear it's stopping at the "GNOME display manager" but we need the full output, to see exactly what the issue is.

Ok, but the full output a few-hundred lines. Can I found on a system in a file, so it is written into a file. Would be
easier somehow copy and paste it. Many thanks!

Ignore this post and read the following posts. (and particularly page 2 of this thread)

Yes, bumblebee is required. For the Debian folks, if one wants to use the nouveau driver, they need to run simple command: sudo apt-get install bumblebee primus
If they want to use Nvidia proprietary drivers, they need kernel headers installed and the command is: sudo apt-get install bumblebee-nvidia primus

Because your distribution uses yum, commands and package names are likely different. The folks I've helped in the past for Debian based systems reported bumblebee needs to be installed for things to work. Debian reference material here, this may help you get a grasp on what you need to do.
