the only thing I can figure is that maybe if cuda-keyring package was already installed, but the repo was not present, that the repo would not be re-added.


sudo apt purge cuda-keyring

might help with that.


Yep, that was it!


$ dpkg --status cuda-keyring
Package: cuda-keyring

I would check to make sure libxnvctrl0 was downgraded properly when the drivers were removed. that can cause some funky stuff. the pinning only defines a preference, but if the current dpkg status is not compatible, ddm-mx won't fix it.

IIRC, when you do a -p operation with ddm-mx, it will remove ...

downgrade libxnvctrl0 ahead of time. I forgot about that one.


sudo apt install libxnvctrl0=525.85.05-1~mx23ahs



That version seems to not exist. However, 525.85.05-3~deb12u1 is installed (now anyways) and a handful of applications depend on it.

Backup took a while.

You suggested timeshift. I hadn't used it before. I've configured it to exclude some stuff and write to the home partition (because the root partition is almost full). It just crashes with an uncommunicated rsync error.

There ARE some older nvidia drivers in the repo's ( enabled and test ) , but realize that your kernel also makes some assumptions and can radically change how the drivers work. I would suggest trying something like dropping back to a 6.12 liquorix kernel, installing the 535.247 or 535.171 drivers ...

Hi @CharlesV, thanks for chiming in.

Will this offer a version selection? I've concluded that 535 drivers are fubar on my system. Hence the need to downgrade.

Apologies. I couldn't make out any solution for the other thread and thought it's perfectly on topic.

QSI for completeness:

Since installing the 535 upgrade end of last year there's several issues with my system, all relating to video. (MX-21 at the time; I've upgraded to MX-23 since)
I'm meaning to downgrade to 525, which I think was installed before and had no issues.

I tried some variations of `ddm-mx -i nvidia -f ...

It installs improperly.
