Nvidia card, blurry display and nouveau [Solved]

Hi, Ive installed BL twice today after trying to sort the display and getting to the point where I felt I needed a fresh start. So im here with a clean install before I mess things up again. I have a nvidia gtx750 running hydrogen 64bit. I enabled non-free repos in the bl-welcome script.

I get the nouveau error messages at the start of the boot text. The display is blurry and Im unable select a resolution higher than 1024x768.

Tried smxi and had an error about kernel headers missing. Then tried installing some different liquorice kernels within smxi but they didnt help. Then after grub I had a blinking cursor so I reinstalled.

I dont need proprietry drivers but SMXI has always been the most simple way for me in the past.

Will nouveau work with my card, if so how do I get the display working properly? Cheers.

Hello smile
Did you try using this guide? NVIDIA Proprietary Driver

Re: Nvidia card, blurry display and nouveau [Solved]

Your card is supported by kernel 4.1 (using the nouveau driver) so you could try either the Liquorix kernel [1] or the kernel version from the jessie-backports repository [2].

Be sure to remove the nouveau blacklist (and any NVIDIA-related xorg configuration files) before attempting this.

Re: Nvidia card, blurry display and nouveau [Solved]

Thank you for your replies Narmo and HoaS.
I discovered this thread which led me to check my sources and I had made the noob mistake of installing without network mirror so I guess that is why smxi failed to get the kernel headers. Does that sound right?

I reinstalled again but this time I moved my PC within cable reach of my modem and enabled network mirror so that all seems to be in order now. The bl-welcome script downloaded a lot of updates this time.

I thought ill follow the debian wiki method Narmo posted instead of always relying on smxi.  Typically anything I try from debian documentation doesnt work for me or i dont understand it and this was no exception...


Debian 8 "Jessie"

As of jessie, the need for the proprietary drivers is pretty much over - nouveau now works quite well and works with dual-headed displays by simple and easy configuring from within your desktop(for KDE see System_Settings/Hardware/Display_and_Monitor/Display_Configuration) .

How can I get to the simple and easy configuring within my desktop? I guess its not in openbox. Do I really need to update to kernel 4.1 to use nouveau?

Ill try the next step that looks simple.

1. Add "contrib" and "non-free" components to /etc/apt/sources.list, for example:

# Debian 8 "Jessie"
deb jessie main contrib non-free

2. Update the list of available packages. Install the appropriate linux-headers and kernel module packages:

# aptitude update
# aptitude -r install linux-headers-$(uname -r|sed 's,[^-]*-[^-]*-,,') nvidia-kernel-dkms


sudo aptitude update
[sudo] password for al:
sudo: aptitude: command not found

Thats where im at, sorry about the TL~DR

Re: Nvidia card, blurry display and nouveau [Solved]

`aptitude` isn't included in BL. Use `apt-get` instead:

sudo apt-get update
sudo apt-get install linux-headers-$(uname -r|sed 's,[^-]*-[^-]*-,,') nvidia-kernel-dkms

(or `apt-get install aptitude`  wink )

Re: Nvidia card, blurry display and nouveau [Solved]

Thanks damo, the apt-get cmd did the trick.

I rebooted after the nvidia install somehow missing step 3 Create an Xorg server configuration file :S  After the reboot I had the blinking cursor so I rebooted to recovery mode and entered the following:

# 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

Now its all looking very good thank you guys big_smile  Next BL install will be on my AAO netbook which has ati graphics so I imagine nouveau will work OOTB.
