Since the upgrade to trixie, I have been experiencing video issues on my main desktop machine (where "video issues" means anything between broken rendering and full lock-ups).

When I run nvidia-detect:

Checking card:ÿ NVIDIA Corporation GF108 [GeForce GT 430] (rev a1)
Your card is only supported by the 390 legacy drivers series, which is
only available up to bullseye.

I'm unsure what driver is being used, but whatever it is, it seems that
I need to change it to something that works better.

You can check with `lspci -v`. Look for the entry for your VGA
controller and then for:

Kernel driver in use
Kernel modules

Also in `lsmod`, the relevant kernel module would be either 'nvidia' (proprietary) or `nouveau` (open source).

Apparently current Nvidia's proprietary kernel module does not support
GT 430 video card anymore. So either find a way to install Nvidia's
version 390 in trixie, or try switching to nouveau, which might be
sufficient, depending on your graphics acceleration needs.

Any suggestions as to how to proceed would be gratefully received.
(Maybe I have to buy a new video card?)

Lately I'm quite happy using Intel's ARC video cards ? kernel module
`xe` (i.e. "driver") is in standard Linux kernel.

Thank you very much.

So looks like I'm already using the open source driver.

Also in `lsmod`, the relevant kernel module would be either 'nvidia'

That seems to confirm the fact.

So it seems that the nouveau driver in trixie has a bug that wasn't present before. I'll see if I can figure out where to report that.

Thank you for your help.

Lately I'm quite happy using Intel's ARC video cards ? kernel module
`xe` (i.e. "driver") is in standard Linux kernel.

I've made a note of that, in case the nouveau bug doesn't get fixed reasonably
quickly.

Pretty much everything one typically needs or wants to know about a GPU and its drivers is available in one command:

All good on my GF108. The GT 630 is a re-release/re-branding of the GF108 GT 430.

Current inxi is available in backports.
