Apologies for the long post. Right now on my box (debian stable) I use a rather seasoned graphic card.
Code: Select all
$ lspci | grep -i --color 'vga\|3d\|2d'
05:00.0 VGA compatible controller: NVIDIA Corporation GF108 [GeForce GT 630] (rev a1)
However, I cannot use this card for GPU computing. Soon (hopefully tomorrow given when I write this) I will get a gtx 1070 with 8Gb of memory which will be enough at least to get me started. Leaving aside the issues of using 2 cards on my box, for now I just plan to replace the old card.
It appears that for a number of algorithms I need to install nvidia-driver, see for instance
https://catboost.ai/docs/installation/c ... aries.html
At the moment, these are the kernels installed on my system
Code: Select all
$ dpkg --list | grep linux-image | grep ii
ii linux-image-4.19.0-9-amd64 4.19.118-2+deb10u1 amd64 Linux 4.19 for 64-bit PCs (signed)
ii linux-image-5.7.0-6.4-liquorix-amd64 5.7-6.1~buster amd64 Linux 5.7 for 64-bit PCs
ii linux-image-liquorix-amd64 5.7-6.1~buster amd64 Linux image for liquorix on 64-bit PCs
In the past, I had no end of trouble with nvidia and company, in particular when installing a new kernel.
The dream would be to install the nvidia stuff that I need and then whenever a new kernel is available, having everything automagically setup for the new kernel.
The nightmare is not to be able to raise any graphical desktop on my system.
I suppose the reality is in the middle. If there no support in debian for nvidia-driver for kernels 5.7.x, but I can get it to work with the 4.19 kernel, well, I can live with that. I still would like my system to be bootable an usable regardless of the kernel I load (if then I need 4.19 for GPU computing, I will accept that).
Finally, in case it helps, I add this link

and I should say I have zero experience in installing drivers directly provided from nvidia.
Any suggestion is appreciated!
