GTX 1650 Ti Mobile Linux Driver 460.39 pci Subdevice 0x3a44

While the driver 450.xx running properly (meet my requirements) the new one obviously do not create a Display Device (DFP-0), ending in an Xorg Error :
(EE) Screen 1 deleted because of no matching config section.

So my Questions are:
While the PCI Device ID 0x1F95 in general is supported ( readme appendix A)
the ID 0x1F95 0x17AA with PCI SubDevice 0x3a44 is not listed there.

  • Is that the reason for the error above?
  • is there a possible “workaround” ?
  • the SubDevice was not listed in 450.xx as well - but working. why??

Thank You for your support!

The subvendor/subdevice only matter in some rare cases where a device specific gpu is used, like some Max-Q devices. You have a normal 1650 Ti mobile.
The error rather sounds like there are some wrong config snippets.
Please run as root and attach the resulting nvidia-bug-report.log.gz file to your post.

Thank you for your quick answer!
There is the requested logfile.nvidia-bug-report.log.gz (1.1 MB)

That won’t really work that way. You AMD gpu is only supported by kernel 5.6+, furthermore, you should rather install the driver from repo, not using the runfile installer. You’re strongly advised to upgrade to debian sid first to have your notebook fully working.
Edit: furthermore, please delete the xorg.conf you created.

Looks like you can also enable buster-backports to get at least kernel 5.9
The package firmware-amd-graphics needs also being updated

Thank you once more,
Now I tried it with Kernel 5.9 (buster-backports) but without luck …
Enclosed is the actual nvidia-bug-report.log.gz (283.4 KB)

Ok, the kernel part of the amdgpu is properly working now but Mesa is too old, saying “unknown chipset”. For AMD Renoir, you need at least Mesa 19.2, please check if that’s also available through buster-backports.

I’m dizzy about the speed of your answers - Thank you!
Unfortunately mesa 19.2 is not offered in buster and/or backports. There is 18.3.6 only.
But this is not a Problem for me at the moment because I’m felicitous to create a xorg.conf for a working HDMI-Display with Kernel 5.9 (default screen remains black). For the moment I’m satisfied, my (minimum)requirements are met! For the mesa I can wait until this version will be offered by debian.

Thank you for your support!

You might be able to use PRIME output despite not having the correct Mesa for the AMD.
Delete xorg.conf
Modify /usr/share/X11/xorg.conf.d/10-amdgpu.conf
to use

Driver "modesetting"

instead of

Driver "amdgpu"

Please create /etc/X11/xorg.conf.d/10-nvidia-prime.conf

Section "OutputClass"
    Identifier     "nvidia"
    MatchDriver    "nvidia-drm"
    Driver         "nvidia"
    Option "PrimaryGPU" "yes"

and add xrandr commands to your display-manager
