Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 24.04 LTS
linux-image-6.17.0-1026-nvidia 6.17.0-1026.26
linux-image-6.17.0-1026-nvidia-64k 6.17.0-1026.26
linux-image-nvidia-6.17 6.17.0-1026.26
linux-image-nvidia-64k-6.17 6.17.0-1026.26
linux-image-nvidia-64k-hwe-24.04 6.17.0-1026.26
linux-image-nvidia-hwe-24.04 6.17.0-1026.26

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
