Re: [opensuse] nvidia vs nouveau on 15.1

...
I just upgraded a 15.0 install to 15.1. I am using an NVIDIA Corporation G70
[GeForce 7800 GT] (rev a1) and the nvidia-304.137 kernel driver from nvidia. I've
been patching this driver for use on the latest kernels for some time now. In fact
on the 15.0 installation I am using it with a vanilla 5.3.0 kernel with no issues.
The reason I cannot use the on kernel nouveau driver is because I can't get it to
support multiple screens. Every monitor connected has the same thing displayed.
...
On the 15.1 box after the upgrade from 15.0 I get this in the  Xorg.0.log log file.
...
[    21.746] ================ WARNING WARNING WARNING WARNING ================
[    21.746] This server has a video driver ABI version of 24.0 that this
driver does not officially support.  Please check
http://www.nvidia.com/ for driver updates or downgrade to an X
server with a supported driver ABI.
[    21.746] =================================================================
[    21.746] (EE) NVIDIA: Use the -ignoreABI option to override this check.
...
My question is how do I implement this "-ignoreABI" thing to override this check?
...
Or maybe a better question might be why does the nouveau driver not support multiple 
screens multiple monitors? Or am I wrong there and just don't know how to configure it?
"Settings/Configure-Desktop" is certainly no help there.
How many screens are you trying to use?

Have you tried using the (newer) default DDX instead of nouveau?

Dual via FOSS is certainly possible. The following three NVidia cards, all newer
than yours, 7, 5 & 2-3 years, need no user configuration except when wanting
placement over/under instead of default side-by-side:

With my middle-aged card, support of each display's preferred mode is only available
when the connection to the 2560x1440 is via dual-link DVI-D, leaving the 1920x1200
on HDMI. If I try to substitute my 2560x1080 for the 1920x1200, both displays top
out at using 1400x1050, even though xrandr reports better modes. It could be that
the combination you are trying is not supported due to age or connector/cable type,
not kernel or X version, surely a regression I would think.
