Strange graphics issues such as flickering application windows and inconsistent display lagging

My computer was acting really strange; the windows were flickering and parts of windows of different applications were partly appearing at random places. Also when I was typing, my computer seemed to automatically selected text and copied it, but it could also be that it just duplicated a part of the screen of a few seconds ago. Hard to describe, but unworkable.

My Thinkpad carbon passed all hardware tests and I installed a fresh Ubuntu install. Still the same behavior. I found a solution that I wanted to share.

The -49 and -50 kernels are flawed, and have been withdrawn. There are graphics issues (possibly only with internal Intel video subsystems).

Boot your computer. At the GRUB menu, select the 2nd choice, Advanced Options (or some such), and select your -48 kernel, or earlier if you don't have -48, and run off of that for now.

Keep up to date with Software Updater and once you see the -51 kernel, or later, then choose it at next boot.

Update #1:

Start Synaptic and install these files (search for 5.8.0-48)...

Run:

ls -al /boot

Confirm that initrd.img-5.8.0-48-generic is there.

If it's not there, then run:

sudo update-initramfs -c -k 5.8.0-48-generic

Then:

sudo update-grub

reboot

At the GRUB menu, select Advanced Options, then select the -48 kernel to boot from.
