hope it's the good one (the internal nvidia card is not in use, but...)

Bonjour,
I own a MSI GT 710
I'm running a debian buster
Here are the outputs of different commands :
lshw : GK208 [GeForce GT 710B]

dmesg : [    6.211259] nouveau 0000:02:00.0: NVIDIA GK208B (b060b0b1)

vainfo: Driver version: Mesa Gallium driver 18.3.4 for NV106

And just an example of syslog that shows that nouveau is looking for nv106
drivers  and fails to load them because I've renamed the firmware directory:
Direct firmware load for nouveau/nv106_fuc084 failed with error -2

In fact, I suppose that, for nouveau driver the card is a nv106 (GK208B, GT
720) but, in fact, it's a nv108 (GK208, GT 710B).

So I've rename /lib/firmware/nouveau/ directory in nouveau.ori to avoid
kaffeine to crash (and vlc too when selecting VDPAU output). But doing so, I
can't expect any hardware acceleration.

PS : I don't know how to find version number of nouveau driver but kernel is 
4.19.0-2-rt-amd64 SMP preempt

Thank's for your work

cordialement,
