Driver for nVidia 6800 GT on debian 10.2 "Buster"
by lukeer from LinuxQuestions.org on (#4ZD8E)
Hi there,
this Linux box needed an upgrade. Debian 10.2 installed fine but didn't get the graphics driver right automatically.
We have here an nVidia 6800 GT.
With nouveau, the colours are weird, psychadelic, wrong. Where there should be a smooth gradient, we get clearly visible stripes of a lot less colours than 24 bit should be able to produce. Orange turns light blue, white stays white. There's a lot of gray on this site (which should be some blue, IIRC), which makes reading the black text impossible without highlighting it.
from /var/log/Xorg.0.log:Code:(II) [drm] nouveau interface version: 1.3.1
[ 19.931] (II) Loading sub module "dri2"
[ 19.931] (II) LoadModule: "dri2"
[ 19.931] (II) Module "dri2" already built-in
[ 19.931] (--) NOUVEAU(0): Chipset: "NVIDIA NV40"
[ 19.931] (==) NOUVEAU(0): Depth 24, (--) framebuffer bpp 32 # <<< here?
[ 19.931] (==) NOUVEAU(0): RGB weight 888
[ 19.931] (==) NOUVEAU(0): Default visual is TrueColorCan there be a problem in the marked line? Or is that completely normal to have a framebuffer with different colour depth from ... whatever?
Starting with the kernel option nomodeset, we get correct colours, but the resolution cannot get over 1024x768, which is undesirable on a FullHD screen.
Creating new modelines with cvt works but they cannot be added through xrandr because there are no output names, just "+default".
The nVidia proprietary driver doesn't seem like an option atm. Buster provides nvidia-legacy back to 340, but the 6800 GT is last supported by 304. I tried adding stretch to /etc/apt/sources.lst, but nvidia-legacy-304xx won't install due to dependencies which apt says are impossible to install.
Is there some configuration for nouveau, which can mitigate the colour problem?
