GV98 adapter, experience with nouveau

[Yury Tarasievich]

I'm trying to put to work the nouveau driver on 
slackware 64 bits current, kernel 4.4.*.

I've thought the hardware to be some obscure OEM 
variant of GT610. However, kind soul on IRC 
pointed out that it's a G98 really, 'GeForce 
9300 GS or 8400 GS'.

Proprietary NVIDIA drivers:
* 340.96 installs okay, console works, but X 
doesn't start, with unspecified error occuring 
when trying to initialise hardware (-19);
* 304.131 works, with no undue surprises.

I've experienced a lot of problems with nouveau 
driver (as packaged for Slackware on Dec 16, 
2015; build date in logs: '19 November 2015 
12:46:02AM'):

1) Console does not initialise the output 
correctly if video mode is not restricted to 
640x480 by kernel command line with '... 
video=640x480'. Any other (bigger) resolution 
there, or no restriction, and the screen blanks; 
also, for either 800x600 or 1024x768 upper 
limits the monitor outputs the warning about 
unusable mode, 26.8KHz/43Hz for 800x600, and 
21.6KHz/27Hz for 1024x768.

The input works. I can log in and start X, which 
starts (!) and works, but produces no output either.

No such problem with NVIDIA drivers.

2) The working mode restriction 640x480 gives 
the console set to 68Hz vertical refresh (as 
monitor reports).

3) The X started from console (having 640x480 
restriction) allows only 640x480 mode in config. 
Any other mode produces working X with blank 
screen, excepting console started restrictred to 
800x600 or 1024x768, which retains the monitor's 
floating message about 'unusable mode'. Either 
way, input in X works.

4) The X in 640x480 has actual vertical refresh 
of 68Hz, which xrandr reports as 75Hz. Attempt 
to change vert. refresh rate to 60Hz produces 
screen 'stroboscoping'. Any other resolution set 
via xrandr produces blank screen.

Any advice? NVIDIA driver files removed, full 
dmesg and xorg available. Cut of dmesg with 
nouveau lines is in postscriptum.

You can display basic video device info via:
$ lspci -knn -d ::0300

Compare output with the
https://nouveau.freedesktop.org/wiki/CodeNames/

Also you can try to test with newer software,
e.g.
https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Spins/x86_64/iso/
Fedora-KDE-Live-x86_64-Rawhide-20160601.n.0.iso

If the machine reaches Desktop in the first place,
put SELinux in permissive mode:
$ su -c "setenforce 0"

otherwise config changes will not apply

re-log ...

Test various Compositor Settings:
$ kcmshell5 kwincompositing

Observe config file:
$ cat ~/.config/kwinrc

Check OpenGL info:
$ kcmshell5 opengl

Check X-Server info
$ kcmshell5 xserver

Start Terminal emulator to exec commands:
ALT+F2: konsole

Re: GV98 adapter, experience with nouveau

[Yury Tarasievich]

Thank you!

Now, I'd appreciate some hints on how to make 
console work, at least.
How are the video modes controlled, e.g., can I 
have some analogue of /etc/fb.modes for nouveau?

After hand-over:
"fb: switching to nouveaufb from VESA VGA"

video device "automatically" switches to the native resolution of the connected display.

If it does not work:

"If you are using packages from your distribution and are unable/unwilling to test the latest versions of all the pieces of nouveau, send the bug reports to your distribution and not directly to us. If you're using an out-of-date software version, our first question will probably be "does it still happen on latest"."
Ref.
https://nouveau.freedesktop.org/wiki/Bugs/

This is why I referred to the "try to test with newer software",
e.g. Rawhide LiveCD/DVDs
https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Spins/x86_64/iso/

I have tested it with NVIDIA G98 here, and it works as expected.

With this approach - test with the "latest and greatest" - you can create a reference point for further comparison - with lower versions of software components.


Godspeed
