As a secondary side effect, I am no longer able to use several function keys. I cannot adjust screen brightness, nor can I disable the wifi card (there may be others, I haven’t tried them all). I can change the settings via plasma widgets. The keys are not recognized in the KDE shortcut mappings. Any advice would be helpful. Thanks.

Could this be caused by a grub configuration issue? My recent bios update was due to a problem with the new shim package, so I’m wondering if there is some other issue with the bootloader. Granted, my knowledge of bootloaders is limited.
Ok, thanks. One more piece of information: Some of the function keys work, but not others. For example, I can toggle the keyboard backlight and change the volume, but the screen brightness and wifi toggle do not work.
I cannot boot the previous kernel with the current shim. However, after the bios update some of the Fn keys stopped working on the old kernel before I ran the update. So, this kernel or the previous kernel, the result is the same.
Try running mkinitrd as root. This will force new detection of hardware. Yes I know just BIOS changr but that may look like new hardware. Also it should have run with new kernel but it never hurst to run it. Worth a try any way.
After thinking about this a bit longer, I think I’ll stay away from the bios downgrade. Is this something that needs to be corrected upstream in the kernel, or can I open a bug report for this? Thanks.
