Thank you so much!
I have two disk drives; one with 22.04 and one with 18.04.3. When the
update rendered 22.04 useless, I switched to 18.04.3. I got your
explanation on how to use different kernels. When 18.04.3 crashed, I tried
using a different kernel. In grub, I selected Advanced options and selected
the previous generic kernel linux-image-5.19.0-31-generic. That immediately
fixed the problem.
Apparently, the linux-image-5.19.0-35-generic has the bug.
Until they get around to fixing the defective 5.19.0-35 kernel, I will use
5.19.0-31 kernel.
Thank you so much, yet again.
This is the first time that I have gotten a work-around for defective code
since I started using Ubuntu MATE.
