My computer configuration is:

Operating System: Dual Boot Windows 10 and Debian 8 Jessie (64 bit)

Motherboard: Asus Z170 PRO Gaming

Graphic card: Nvidia GTX 1080 (Reference/Founder Edition)

Processor: Intel I7-6700K

Memory: 16 GB - 2 x 8GB 3200 mhz (probably crucial, I forgot...)

Hard Discs: SSD m.2 512 GB Liteon (NVMe, Debian 8 Jessie) SSD MX300 1050 GB (Windows 10 installed)

SSD OZ SATA 2 30 GB (nothing already installed, but I will add this space later to my Debian for testing, sandbox, etc...)

Monitor: Dell U3415W (21:9)

After two days when I was trying to make a dual boot system (known issue with GRUB installation on NVMe disc), I finally installed it properly :). Now I have problem with display resolution and other drivers, my current detected resolution is 1024 x 768 (4:3) - "Unknown Display", however it should be 3440x1440 (21:9). Details below:

I already run apt-get update && apt-get upgrade, but I still have resolution issue. I found few solutions on Ubuntu forum, however it didn't work for me.

My source package list contains only the "main" from https://wiki.debian.org/SourcesList (- an example of a sources.list for Debian 8/Jessie. I cannot paste it, because I can't paste more then two links...)

My questions are:

  1. What I need to do to fix issue with resolution?
  2. Looking into my lspci -v values, can anyone tell me what drivers I'm missing and what I need to do to fix it?
  3. Can anyone confirm that my source package list is correct?
  4. Is it true that GTx 1080 is only supported by Debian 8 Jessie-backports distribution?
0

I have figured out that I need to below entry to sources.list:

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

I have added also contrib non-free entries, now it looks like below:

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

deb http://httpredir.debian.org/debian jessie-updates main contrib non-free 
deb-src http://httpredir.debian.org/debian jessie-updates main contrib non-free

deb http://security.debian.org/ jessie/updates main contrib non-free 
deb-src http://security.debian.org/ jessie/updates main contrib non-free

jessie-backports

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

After that I run:

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

apt-get update

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

As provided in the link by GAD3R (many thanks bro, first beer on me :)). Screen resolution works good now :).

Just to make sure, can anyone check my sources.list? What are the concerns of adding contrib non-free? I read few articles about it, however I would like to hear it from you with simple language.

My lspci -v, looks now as:

Can you confirm that everything is good?

I also run glxinfo | grep OpenGL:

OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce GTX 1080/PCIe/SSE2 OpenGL core profile version string: 4.4.0 NVIDIA 375.26 OpenGL core profile shading language version string: 4.40 NVIDIA via Cg compiler OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL core profile extensions: OpenGL version string: 4.5.0 NVIDIA 375.26 OpenGL shading language version string: 4.50 NVIDIA OpenGL context flags: (none) OpenGL profile mask: (none) OpenGL extensions: OpenGL ES profile version string: OpenGL ES 3.2 NVIDIA 375.26 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20 OpenGL ES profile extensions
  • After installing the required package , open the terminal and run nvidia-xconfig command to generate the /etc/X11/xorg.conf file then run nvidia-settings – GAD3R Feb 25 '17 at 15:13
