A just finished test install of the (same) Ubuntu 22.04.1 Desktop ISO now resulted in the gcc-12 being automatically installed, and the Nvidia 545 driver modules successfully compiling. After a fresh install, set up wireless, installed build-essential, and then used software & Updates/Additional drivers to select the Nvidia 545 driver, which successfully compiled (gcc 11.4) under the 5.15 kernel. Ran apt update, and the new 6.5 kernel and gcc-12 were downloaded, and the nvidia 545 modules successfully compiled with the gcc-12. Looks a fix has been applied to get the gcc-12.

The previous 6.2.0 series kernels were compiled with gcc-11. The current version of gcc in jammy is 11.4. Many NVidia drivers, wifi drivers, VirtualBox (from our Repo), etc fail to build the modules, because of a gcc compiler version mismatch between what the current running kernel was built by, and the module being built. I recognized this while helping Users with NVidia driver compile errors on the forum, and came up with this work-around for them: https://ubuntuforums.org/showthread.php?t=2494273&p=14175164#post14175164 Summary: Install gcc-12 & g++-12 on 22.04.3 and use it as the compiler. Since then, this work-around has helped to resolve problems with running the 6.5.0 series kernels and building modules for other applications and hardware drivers: VirtualBox, WiFi Drivers, etc. for use with the 6.5.0 series. I have run this for over a month as my default with no ill affects. I have continued to recommend this work-around to many user to solve their problems... *** I think it is time to look at pushing through gcc-12 as the default compiler for 22.04.3 through the normal updates channel.
