32-bit packages for 460.27

GPU Unix Graphics Linux
#1

It appears as if I currently have a choice of running either CUDA or Steam on my machine, because CUDA 11 requires a version of the driver that is only available from your site, and Steam requires the 32-bit libraries, which you’re not currently hosting, as far as I can see.

Do you have plans to release the 32 bit versions at any time?

The cuda bundled driver doesn’t provide the 32bit compatibility libs and never will. You’ll have to use the normal graphics driver and install just the cuda toolkit:

  • purge anything nvidia/cuda
  • install the driver using the Software&Updates application
  • download the cuda .deb
  • add the repo to your system
  • follow the steps from install instructions on downloadpage but omit the last one
  • i.e don’t install cuda
  • instead, run sudo apt install cuda-toolkit-11-2

Well, i’ve managed to bork something quite impressively then.

I’ve purged everything nvidia/cuda related, rebooted to make sure that i’m using nouveau, and then installed the 455 versions from my distro repos, and now it just doesn’t work at all. Everything’s showing as 455, and modinfo on all of the loaded modules shows 455, but now whenever I run nvidia-settings or nvidia-smi it errors out complaining about a module mismatch and this appears in my dmesg:

[ 369.644663] NVRM: API mismatch: the client has the version 455.38, but
NVRM: this kernel module has the version 460.27.04. Please
NVRM: make sure that this kernel module and all NVIDIA driver
NVRM: components have the same version

I have no idea where it’s still finding 460.27 for, but it’ll show up, i’m sure.

Please try removing anything nvidia again, then use
dpkg -l |grep nvidia
to find stray packages to manually remove.
