I am using a Multi-GPU system with, beside others, two ASUS Nvidia GT520 graphic cards. For those, the NVidia driver 390.157 is the last one supported. It works ok (it has some minor issues) with Kubuntu 22.10 with kernel 5.19 on architecture x86_64.

Because of the GOP situation, I use the Intel IGP graphics adapter UHD Graphics 750 to boot and use the GT520 as further display outputs.

Now my questions are:

  1. How can I use the/an NVidia driver version 390 with the kernel 6.2 (23.04)?
  2. How can I use the nouveau driver to make this work with kernel 6.2 (23.04)? (If 1. is not applicable)

So how can I make this setup work?
And could I upgrade to Kubuntu 23.04 flawlessly?
Or do I have to wait for future bugfixes (if they will ever come)?

(The graphic cards do work ok for my needs, so I don't need or want to buy new ones.)

Others have had this exact problem before:

    I can't fully answer your question, but I can offer a data point - the 390.157 driver failed for me after upgrading to 23.04 from 22.10. I was able to switch to noveau, but lost Wayland in the process (X11 only). – Stephen Rudolph May 13 '23 at 19:56
  • @StephenRudolph: Thanks for sharing your experience/partial answer that 23.04 does not fully support the 390 driver yet. So an update seems not to be sensible atm. – zx485 May 13 '23 at 23:30

    @zx485 - I found an Ubuntu 6.2 kernel bug tracker for this driver: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-390/+bug/2019869. The bad news is that the author claims the "nvidia 390 driver is unmaintained." It looks like a fix is out for the in-development version of Ubuntu, but as I write this, the haven't released the update for 23.04. – Stephen Rudolph May 23 '23 at 03:56

    My experience is the same with @StephenRudolph, I had to use noveau and give up on Wayland with kernel 6.2 (Ubuntu 23.04). The bug tracker status is Fix Released, but from my own experience the fix (nvidia-driver 390.157-0ubuntu5.23.04.1) does not fix anything... – IronGeek Jul 30 '23 at 15:57

    I can confirm too, the package nvidia-driver-390 version 390.157-0ubuntu5.23.04.1 does not fix anything for me on GTX 660M. The behaviour is the same it was before: just after the boot logo is shown briefly (perhaps iGPU is used during boot process), but after that it's just a black screen with blinking underscore in upper left corner. – Jarek Przygódzki Aug 21 '23 at 07:47

Thank you all for your interest and support in this topic.

Unfortunately there seems to be no further effort by NVidia for supporting the 390 version of the driver for kernel version 6.2.xx, as mentioned here by the NVidia moderator aplattner:

The legacy release 390 series of drivers is out of support, [...]
