NVIDIA Quadro K2200 - which graphics driver?

English Install/Boot/Login
1

Hi there!

An older Xeon Dell Precision Desktop (8x E5420 @2.5GHz, HT active iirc) I installed with TW some weeks ago. Graphis is now K2200 (has been NVS295 in the beginning). I tried without and with NOUVEAU (xf86, mesa-dri) no difference.

Problem: If I watch a little TV via kaffeine (DVB-S2, version 2.0.40-86.5-x86_64 from KDE_unstable_EXTRA) the frames stick (no constant picture stream) quite annoying.

System Information gives:

Graphics Processor: llvmpipe

And kaffeine complains:

Any ideas how to have better graphics** without the NVIDIA driver**? I don’T want the pain of re-installing after every kernel update…

https://nouveau.freedesktop.org/VideoAcceleration.html
https://wiki.archlinux.org/title/Hardware_video_acceleration

Install needed packages: search for “vdpau” (libvdpau_nouveau, etc.).
Install firmware from Nvidia.

Or VM + Leap + Nvidia drivers?

Quadro K2200 = GM107 - Maxwell graphics has bad support with nouveau. Use Kepler with nouveau.

It is rather stupid to use Nvidia Quadro with nouveau.
Change it to Nvidia Kepler or AMD or Intel graphics.

Manythanks for taking time to reply!

vdpau is installed, I found a vdpau driver in software management and installed, didn’t change it.

Extracted firmware from nouveau page, the console output when starting kaffeine is absolute identical to the situation befor installing…

You propose buying new hardware?

4

changed back to NVS 295 and booted to LEap 15.3, no errors in console with kaffeine starting and nice audio and video quality…

5

…rebooted back to TW, no adequate adio/video quality with same hardware. Strange…

6

:frowning: Yet another thread writing as though there is only one Nouveau meaning. Learn what Nouveau means here. Now that you know, which D?X driver are you using on Leap? Which D?X on TW? Does behavior change by switching to another?

Registering to that forum would enable access. There’s an earlier version that’s less refined here on this forum, where editing as facts and hardware change, or clarification is needed, is not allowed.

I personally don’t use any drivers and don’t need any.
The fact is your computer and openSUSE must use drivers. Without drivers, you can’t even begin an installation, and live media won’t begin to boot.

Afaik TW and Leap make decisions to use drivers.
The decisions are nearly always which driver to use, not whether to use a driver. Sometimes there is a single choice. With X drivers for AMD, Intel and NVidia GPUs, there are usually two choices of competent FOSS drivers, and two choices of crude fallback/troubleshooting drivers that most people would not tolerate for everyday use.

But that is nothing a user should care for. Software (especially OS) should make sensible decisions to utilize hardware capabilities available. I don’t sit in a car and start with adjusting the motor tuning before starting a ride. Sorry, that should simply work ootb…
While working OOTB is a reasonable expectation, sometimes it just can’t happen. Developers simple cannot test every possible hardware combination that exists in the real world. Some problems only get fixed because a user reported a problem that QA and developers never experienced. Sometimes the optimal driver can only be determined by trying each that is available, not programmatically.

9

Hmm, one moment. Leap makes a reasonable choice that works, TW doesn’t. Easy as that…

I highly appreciate your competent answers, but am I really supposed to read through a highly technical 4 page thread just to watch a little DVB-S2 on TW? This simply can’t be true…

10

No, you’re not. However, at the openSUSE link, reading the OP is enough for the gist, the definitions involved. It was intended to be a sole post, not a thread, and certainly not 34 posts (1.7 pages for me; 20 posts per page).

There is no “thread” at the original link provided. This simplification and clarification is what editing allows, permitted there, prohibited here.

11

Ok, but how to check what the Leap/TW actually uses? Which command will show?

12

Removed (again) xf86-video-nouveau. The xf86-video-nv is not installed. Rebooted.

I now have in /var/log/Xorg0.log

The video and audio quality is very poor (even worse than yesterday). What am I doing wrong with TW, while Leap 15.3 is doing fine?

PS:

vdpau is installed, I guess

I also remove xorgX11-driver-video from TW now, no improvement…

15

For the prosperity of a human kind use Nvidia Quadro only with Nvidia’s proprietary driver.

NVS 295 has G98 chip and get some acceleration with nouveau drivers: https://nouveau.freedesktop.org/VP4.html
Quadro K2200 has no support for video acceleration, and possibly will not have it in future.

Sell these cards and buy AMD/ATI cards.
You need Terascale (Radeon HD 2000 series) or better (UVD 3.0 or better is preferable).

For full graphics info, inxi must be run from a GUI environment (Konsole, Xterm, etc.).

It can be gleaned from Xorg.0.log as well if you know the multiple things to look for. What to look for is not easy to explain.:

# grep -i matched /var/log/Xorg.0.log | grep -v set\(0\)
   126.821] (==) Matched nvidia as autoconfigured driver 0
   126.821] (==) Matched nouveau as autoconfigured driver 1
   126.821] (==) Matched nv as autoconfigured driver 2
   126.821] (==) Matched modesetting as autoconfigured driver 3
   126.821] (==) Matched fbdev as autoconfigured driver 4
   126.821] (==) Matched vesa as autoconfigured driver 5

Above shows all possible first level X drivers.

# egrep 'modeset|nouveau|nv' /var/log/Xorg.0.log | grep -v set\(0\)
   126.821] (==) Matched nvidia as autoconfigured driver 0
   126.821] (==) Matched nouveau as autoconfigured driver 1
   126.821] (==) Matched nv as autoconfigured driver 2
   126.821] (==) Matched modesetting as autoconfigured driver 3

   126.822] (II) Module modesetting: vendor="X.Org Foundation"
   126.822] (II) modesetting: Driver for Modesetting Kernel Drivers: kms

Above shows only the modesetting driver reached the bottom several entries, indicating it’s the one selected for actual use.

Another determination is noticing the driver name appearing most. Most of the time, output from the following should make the name of the driver in use evident:

# grep \(0\): /var/log/Xorg.0.log | wc -l ; grep \(0\): /var/log/Xorg.0.log | tail

Just noticed one I always missed before:

# grep 'using drv /dev/dri/card' /var/log/Xorg.0.log
   243.632] (II) modeset(0): using drv /dev/dri/card0

The string preceding (0) is either the driver’s name, or its nickname. If there is more than one GPU, then there may be a driver associated with (1) as well as (0).

18

It’s a meta-package. Removing it means any xf86-video-* that you remove should not be automatically reinstalled.

19

Is libvdpau_nouveau installed?

20

Nope, but as Leap 15.3 does fine without this piece of software I don’t think it will help, or?
